High-Leverage Skills to Learn

Most kids finish junior high at 15 or 16, right at this age threshold. Hiring anyone under 16 is illegal; each underage worker used results in a $5000 monthly penalty. Thus, any employer willing to hire you is knowingly breaking the law. Should anything go wrong, medical bills and compensation must be paid by that employer. If it refuses or goes out of business, there’s no one else to cover those costs.

Cost

Zero. It takes just a minute to figure out how old you are.

Benefit

Article 11 of the Compulsory Education Law states: “All children aged six or older must be enrolled by their parents or legal guardians to receive and complete compulsory education.” Article 14 adds: “Employers are prohibited from hiring children and adolescents required to attend compulsory education.” Article 58 says that failure to enroll eligible kids without valid reasons results in “criticism and a directive to correct the issue within a set timeframe” from local authorities. Article 2 of the Regulations on Banning Child Labor declares that government agencies, social groups, enterprises, private non-profit entities, and individual businesses “must not hire minors under 16.” Article 6 imposes a $5000 monthly fine per underage worker; noncompliance raises this to $10000 per month. Article 7 levies a $5000 fine per child referred for employment. Article 10 mandates that employers “must arrange medical treatment and cover all related costs” if a child worker falls ill or sustains injury; additional compensation applies in cases of permanent disability or death. One exception exists under Article 13: cultural or sports organizations may hire under-16 professionals with parental consent (nationwide).

Note

You’re the primary beneficiary here. Working legally is permitted after age 16. Yet jobs open to a 16-year-old with no qualifications align precisely with those highlighted in Section 10—roles relying on routine tasks most vulnerable to automation. Section 19 outlines overtime pay, vacation rights, and worker’s compensation, all contingent on formal employment status and verifiable records. As an unregistered worker, you lack both, meaning you won’t qualify for these protections or benefits.

For every additional year of schooling, the average risk of dying in adulthood drops by about 1.9%. This effect is strongest among people aged 18–49, where the reduction is roughly 2.9% per extra year; for those over 70, it’s only 0.8%. Those who manage to stay in school tend to come from more privileged backgrounds, so it’s hard to isolate exactly how much of this benefit stems from education itself.

Cost

There is no monetary cost. The expense lies in the time and effort required to stay in school; tuition fees are covered under Section 4 of this chapter (vocational school tuition and grants). The real challenge is maintaining persistence — staying in school without dropping out.

Benefit

This conclusion comes from a comprehensive meta-analysis that pooled findings from 603 separate studies conducted in 70 locations across 59 countries between January 1980 and May 2023. There is a clear dose-response relationship between years of schooling and adult mortality (all causes combined): each extra year reduces mortality risk by an average of 1.9% (95% confidence interval: 1.8–2.0). For individuals aged 18–49, the reduction is 2.9% per year (2.8–3.0); for those over 70, it’s 0.8% (0.6–1.0). No significant gender differences were observed, nor did socioeconomic development level appear to influence the effect.

Note

This finding remains controversial. The authors themselves reported evidence of publication bias (p<0.0001), meaning studies showing stronger effects were more likely to be published. Results also varied widely across individual studies. All included research relied on observational tracking rather than controlled trials. Because years of schooling correlate closely with family background, regional factors, and occupation, it’s difficult to determine how much of the 1.9% reduction is truly attributable to education versus other advantages enjoyed by long-term students. Conversely, individuals with childhood illnesses or mental health issues are more prone to dropping out and dying earlier, which could artificially inflate the apparent educational benefit. Thus, while this data clearly shows a positive link between education and longevity, it does not prove that “each extra year of schooling adds 1.9% to your lifespan.” The overall benefit is classified as modest: most readers will only gain a few extra years at most by staying in school an additional three or four years, so the impact remains relatively small. The primary beneficiaries are the individuals themselves. 〔10355〕

According to the 2020 census, only 15467 people per 100000 nationwide have completed college or higher education — that’s roughly 15%. Meanwhile, 34507 people per 100000 have only a junior high school education, making this the most common level of education. On average, people aged 15 and older have attended school for just 9.91 years, barely enough to finish junior high. Therefore, a junior high school education in China is far from “sufficient” — it is simply the baseline level for most people.

Cost

Zero. All you need to do is glance at the numbers below.

Benefit

The reference point for the seventh national census was November 1, 2020. At that time, 218360767 people nationwide had a college education or higher, while 213005258 had a high school education (including vocational school). The number of people with a junior high school education was 487163489, and those with a primary school education totaled 349658828. Compared to the sixth national census in 2010, the number of people per 100000 with a college education rose from 8930 to 15467, while those with a high school education increased from 14032 to 15088. Conversely, the number of people with a junior high school education fell from 38788 to 34507, and those with a primary school education dropped from 26779 to 24767. The average years of schooling for people aged 15 and older rose from 9.08 to 9.91 years, and the illiteracy rate declined from 4.08% to 2.67%.

Note

These figures only indicate how common or rare a given level of education is within the general population. Whether it makes financial sense for any individual to pursue further education should be calculated using the method outlined in Section 6 of this chapter (“How to weigh the costs and benefits of education vs. working”). Also, note that census data includes all residents nationwide, including children and the elderly. The proportion of young people with a college education is significantly higher than these averages, so comparing one’s own educational level to these figures may overestimate one’s competitive advantage. Conversely, these numbers do provide solid evidence to refute the claim that “education is useless,” since they represent the entire labor force competing for jobs. The ultimate beneficiaries of this education are the individuals themselves.

At public vocational schools, tuition is waived for rural students, urban students in agriculture‑related programs, and those from low‑income families. Starting spring 2025, a 2300‑yuan grant is available each year for both vocational and regular high‑school students. College students receive a 3700‑yuan grant annually, and they may borrow up to 20000 yuan per year via student loans. The exact amount of the grant is 0.7 yuan, which is a fixed figure set by policy. If funds remain insufficient, repayment can be deferred or alternative options explored — most students never have to drop out to work right away.

Cost

Zero out‑of‑pocket expense. Before school starts, simply visit the school’s student‑aid office and submit the required paperwork.

Benefit

The tuition‑waiver policy for public vocational schools has been in place since fall 2012; it covers all full‑time first‑, second‑, and third‑year students who are rural (including those in county towns), enrolled in agriculture‑related programs, or from financially disadvantaged families (except for students in performing‑arts majors). In 2024 the student‑aid framework was updated: the national grant for undergraduates rose from 3300 to 3700 yuan per year, and the National Inspirational Scholarship increased from 5000 to 6000 yuan, both effective fall 2024. For vocational and regular high‑school students, the grant also rose from 2000 to 2300 yuan per year, effective spring 2025. Student loans were adjusted as well: from fall 2024 undergraduates may borrow up to 20000 yuan per year (previously 16000) and graduate students up to 25000 yuan (previously 20000). The interest rate equals the applicable LPR minus 70 basis points.

Note

These benefits apply to the student and his or her children. Exactly which groups qualify for tuition waivers and how many grant tiers exist is determined by each province. Private schools receive subsidies based on local public‑school standards, but any shortfall must still be paid by the student, so it’s wise to verify local rules before enrolling. Student loans are loans, not grants, and must be repaid after graduation; they simply separate the immediate cash‑flow problem from a longer‑term cost‑benefit analysis — don’t treat a temporary shortfall as a permanent barrier. Section 7 discusses training subsidies and emergency aid for periods of unemployment; families facing sudden income loss should apply for those programs first.

The Vocational Education Law enacted in 2022 explicitly states that vocational education holds equal status to general education. Secondary vocational schools can enroll students through linked admission programs with higher vocational institutions, which in turn must reserve a set proportion of their enrollment slots or hold separate exams specifically for secondary vocational graduates. Employers are also prohibited from setting eligibility barriers based on a candidate’s vocational school background. Failing to meet the cutoff for regular high school admission simply means you get to choose a different path — it does not leave you stuck with a junior high school diploma.

Cost

No cost at all. Before submitting your high school entrance exam applications, check your province’s official vocational education admissions platform once.

Benefit

Article 3 of the Vocational Education Law (effective 1 May 2022) stipulates: “Vocational education is an educational type that holds equal importance to general education.” Article 37 states that secondary vocational schools “may, in accordance with relevant national regulations, implement linked admission and training programs with higher vocational education for designated majors.” Higher vocational institutions “may, in accordance with relevant national regulations, admit students via assessment methods that combine academic ability and vocational skills.” Provincial-level and above education authorities are required to build unified vocational education admissions platforms to publish information on schools, majors and enrollment quotas, and provide application query services. Article 53 further specifies: “Students from vocational schools enjoy equal opportunities as students from regular schools at the same level in terms of further education, employment and career development.” Higher vocational institutions and regular universities offering vocational education “must reserve a corresponding proportion of their enrollment quotas or hold separate exams to admit vocational school graduates specifically.” It is also forbidden for employers to set application, hiring or employment criteria that prevent vocational school graduates from competing on an equal footing. For positions requiring specific vocational skill certifications in public institution recruitment, “educational requirements can be appropriately lowered” nationwide.

Note

These benefits apply to both yourself and your children. All the channels outlined here are legally mandated, but they do not guarantee admission. The specific majors covered by linked training programs, the exact proportion of slots reserved for separate admissions, and the exact subjects tested in vocational college entrance exams are all determined by each individual province. Before submitting applications, you must check your province’s current vocational education admissions platform and enrollment quotas — do not rely on rules or practices from other provinces. When selecting a secondary vocational major, use the criteria outlined in Section 10 of this chapter (choosing skills that are less prone to automation) as a reference: majors that require on-site work in non-standard environments are less likely to be phased out. To pick a school, confirm it is listed in your province’s current vocational education enrollment plan. Verify any certificates issued by the school using the three-step process described in Section 8 (checking whether a certificate is on the official approved list). Avoid any recruitment materials that make promises like “guaranteed job placement” or “100% admission success” at all costs.

Lay both options side by side on paper. Working early yields only three years of wages from low‑skill jobs. Continuing education, on the other hand, delivers extra yearly earnings for the next three or four decades. In Chinese cities, each additional year of schooling raises average income by roughly 4.0% (in 1988) up to 10.2% (in 2001). These figures are somewhat dated and should be viewed only as rough estimates.

Cost

There is no monetary cost. Setting aside about half an hour to do the math is all it takes.

Benefit

This estimate applies to Chinese urban areas between 1988 and 2001. The percentage increase in income linked to one extra year of schooling is known as the return on education. The original text notes that this rate rose sharply from 4.0% per year in 1988 to 10.2% in 2001, especially after 1992. It reflects the growing wage premium enjoyed by university graduates compared with those without higher education. This figure offers a locally relevant benchmark for converting “one extra year of study” into an expected lifetime income gain. For a global average, see Section 7 of this chapter (global average return on an extra year of schooling).

Note

Before performing the calculation, subtract the tuition waivers and grants mentioned in Section 4 (vocational school costs and aid), as well as the mortality impact discussed in Section 2 (extra year of schooling and mortality). The data end at 2001 and cover only urban residents, so they cannot be directly applied to today’s situation; the same caveat applies to the 9% global average cited in Section 7. Results will naturally vary from person to person. For individuals facing high tuition fees, mismatched majors or occupations, or lengthy study periods, the net benefit may indeed be negative — but this only indicates that that particular path is unwise, not that education as a whole is worthless. Several factors cannot be captured by the formula: legally mandated educational requirements (see Section 5 on integrated vocational admissions and separate exams), resistance to automation (see Section 10 on selecting automation‑resistant skills), and the possibility of switching careers. Ultimately, the benefits accrue to the individual.

Globally, each extra year of formal schooling translates into about a 9% annual increase in personal income; this benefit tends to be higher for women than for men. This figure applies to regular schooling, not to short courses or workshops. Think of it as a yardstick: if a course costs 30000 yuan and lasts half a year, ask whether its expected income boost matches what one extra year of schooling would deliver.

Cost

No cost at all. Memorize this figure and use it as a benchmark for evaluating any “learning opportunity.”

Benefit

A comprehensive review covering 1120 estimates from 139 countries between 1950 and 2014 found that the worldwide average private return on each additional year of schooling is 9% per year. This private return is the portion that directly affects an individual’s earnings — on average, an extra year of schooling raises income by 9%. The private return on higher education is on the rise, while the social return on education (the benefit to society as a whole) remains substantial. Women continue to reap higher average returns than men from schooling.

Note

This is a global average for “one extra year of schooling” and should not be taken as the expected return from a single course or workshop, nor as a figure specific to China. It serves merely as a rough reference point. Its main purpose is to provide a standard for evaluating any training program: if a course demands a 30000‑yuan investment and six months of effort, you can gauge whether its income impact is comparable to that of one additional year of formal education. Keep in mind that this average masks considerable differences across fields and countries.

Some organizations run training programs, charge fees, and issue certificates under the guise of new occupations or skill levels, while others even impersonate authoritative institutions. The Ministry of Human Resources and Social Security has taken targeted actions to curb such practices. Before enrolling, follow three steps: confirm whether the occupation is listed in the National Vocational Qualification Catalogue; verify that the issuing agency is registered with the Ministry; and check whether the certificate number can be found on the official platform. If any of these checks fail, any money spent on enrollment is essentially wasted.

Cost

No cost at all. It takes just a few minutes to check once.

Benefit

The Ministry has launched nationwide efforts to address these issues. Official documents specifically identify the problematic practices as “some organizations and entities arbitrarily running training, evaluation, and certification activities under the banner of new occupations, skill levels, etc., charging excessive fees and issuing certificates indiscriminately; others making false or exaggerated claims, even impersonating authoritative institutions to organize training, evaluation, and certificate issuance.” Related measures include joint crackdowns with authorities such as Cyberspace Administration, public security, and market regulation to “severely punish any evaluation or certification activities conducted by unregistered agencies or those not approved by the Ministry.” Illegal promotional content on websites and social media is also shut down per law. Additionally, the Ministry urges the public to learn how to verify certificate legitimacy and value.

Note

Follow this exact sequence for verification. First, check whether the occupation appears in the National Vocational Qualification Catalogue; if not, it is not a nationally recognized qualification. Next, confirm that the issuing agency is registered with the Ministry. Finally, use the official platform for skilled worker qualification certificate queries to see if the certificate number returns a valid result. Do not enroll if any step fails. Certificates bearing terms such as “International”, “Advanced”, “Registered”, or those promising “guaranteed passing results” or “income from certificate registration” carry the highest risk.

From 2025 through late 2027, the government plans to provide subsidized training to over 30 million participants. Funding comes from multiple sources, including employment assistance funds, unemployment insurance funds, and corporate education budgets. The more in-demand a profession is and the higher the training cost, the larger the subsidy. Employees should ask their employers first; everyone else should review their local Human Resources and Social Security Bureau’s subsidy list before deciding what to study.

Cost

Zero cost, or at least a substantial reduction. Training does require time. The real challenge is resisting the urge to sign up for paid courses right away; first, check the local subsidy list.

Benefit

The national target is clear: over 30 million subsidized training slots for high-tech industries, critical sectors, and priority employment groups between 2025 and 2027. Funding is pooled from various programs — employment assistance funds, unemployment insurance, sector development grants, East-West cooperation funds, and corporate education budgets. Subsidy amounts depend on how urgently a profession is needed and its training cost; they vary by occupation. Companies must also allocate at least 60% of their employee education funds to frontline staff training.

Note

Exact eligibility criteria and subsidy amounts are set by each province. The main portals are the “Subsidized Vocational Training List” on the local Human Resources and Social Security Bureau website and public training centers. Section 7 covers unemployment-related training subsidies (up to three applications per person) and social insurance benefits. Employees should first inquire about their employer’s education fund allocation before making any decisions. Checking the subsidy list first saves far more money than choosing a course first and then searching for financial aid.

According to U.S. estimates, roughly 47% of jobs carry a relatively high risk of being taken over by computers. Later studies that evaluated individual tasks instead yielded a much lower percentage. Three core challenges currently prevent machines from handling certain jobs: manual dexterity, creative problem-solving, and social interaction. Hence, roles that demand physical work in unpredictable environments and real-time decision-making are far less likely to be automated, while jobs with rigid processes and heavy information processing carry the highest risk.

Cost

No cost at all. Before making a choice, run through the skills you’re considering using this criterion as a filter.

Benefit

This study assessed 702 U.S. occupations to estimate the likelihood of each being automated — the result showed that about 47% fell into the high-risk category. The three aforementioned challenges form what the authors call “engineering bottlenecks” that limit automation potential. These include sensory perception and physical manipulation (finger and hand dexterity, working in cramped or awkward spaces), creative intelligence (the ability to devise novel solutions), and social intelligence (interpersonal interaction). Consequently, occupations requiring hands-on work in unstructured settings and on-the-fly judgment are consistently less prone to automation, rather than this being a random trait of specific jobs. Roles with standardized workflows and information-centric tasks face the greatest automation risk.

Note

This research is somewhat controversial. It originated as an unpublished draft paper from 2013 that measured the overall automation potential of entire occupations. Later studies that evaluated individual tasks instead produced a significantly lower high-risk percentage. The paper also does not specify a timeline for when automation might occur. When using these findings, avoid fixating on the 47% figure; instead, focus on the three key bottlenecks it identifies. Jobs involving on-site installation, maintenance, and caregiving are far more resistant to automation than purely clerical roles for precisely these reasons. Therefore, when deciding which skill to acquire, prioritize those that demand physical work in non-standard environments.

The government is promoting a “New Eight-Level Worker” system that requires companies to link job pay to employees’ skill levels. Outstanding workers can even have their skill grades recognized regardless of seniority or years of experience. This is the policy direction, though implementation varies widely across regions and companies. Only skills with established national occupational standards and grading pathways can eventually lead to pay increases based on those grades — so it’s worth checking first before you invest time in learning them.

Cost

No cost involved. One quick check is all you need.

Benefit

The government is actively rolling out this New Eight-Level Worker skill grading system. Official documents explicitly require linking skill grades to employee compensation, stating that “a skill-oriented pay distribution system must be strengthened... companies should adopt a compensation model that ties both job value and skill levels to pay.” Regions are also being urged to “expand the evaluation and hiring of senior-level workers and increase the frequency of such evaluations.” Eligible companies can conduct their own skill assessments for employees, and top performers can have their skill grades recognized without needing to meet any requirements related to years of service, prior grades, or seniority.

Note

This is the intended policy direction, not a guarantee of actual pay increases — implementation varies greatly by region and company. The key takeaway for anyone considering learning a new skill is to first verify whether it has corresponding national occupational standards and a formal grading pathway; only then can it potentially lead to pay raises based on skill level. For skills lacking any official grading system or industry entry requirements, learning them won’t guarantee any career or financial benefits — you’ll still need to find work on your own.

The amount of training subsidies each region offers for a given occupation is set based on how urgently that occupation is needed and on the cost of training. Thus, the subsidy level itself shows whether workers are in short supply locally. Claims online about “monthly earnings for a certain job” are usually just posted rates on hiring platforms or self‑reported figures. Those figures come mainly from people who are already earning money, and they ignore working hours, commuting time, occupational illnesses, and seasonal fluctuations.

Cost

No expense at all. You just need to look up two local documents.

Benefit

The subsidy amounts serve as an official measure of which occupations are in short supply. Policies require “a differentiated subsidy system based on how urgently an occupation is needed, its training costs, and other factors,” so each area defines its own list of subsidized vocational training programs accordingly. Consequently, the difference in subsidy levels for the same occupation across cities directly reflects how much that occupation is in demand locally.

Note

Official wage statistics are broken down only into five broad occupational categories; no figures exist for individual jobs. According to 2025 data from the National Bureau of Statistics, the average annual wage at large‑scale enterprises is roughly 106,080 yuan. Managers at mid‑level and above earn about 210,016 yuan per year, while professional and technical staff earn around 155,491 yuan. Clerical workers earn 94,936 yuan, production workers 80,739 yuan, and workers in social services and daily life sectors earn 79,857 yuan. The Ministry of Human Resources and Social Security publishes a “Top 100 Occupations in Short Supply” list on the China Employment Network; the latest edition covers the fourth quarter of 2022 and is compiled from recruitment and job‑seeker data collected by public employment services in 102 cities nationwide. Most online claims about monthly earnings for specific jobs are based on posted rates or personal reports — figures that come largely from those already earning money and that do not account for working hours, commuting, occupational hazards, or seasonal variations. To gauge true labor demand, consult the subsidy lists on your local Human Resources and Social Security Bureau website and check the rankings of job openings compiled by public employment services. Finally, talk to current workers on construction sites, in factories, and at retail outlets. 〔106000〕 〔210000〕 〔155000〕

Government policies favor short-term training programs and micro-specializations at vocational colleges that lead to quick employment. The sole criterion for selecting such programs is whether they offer a concrete job opportunity upon completion. Programs lasting a year or more, which require additional “experience-building” after graduation, end up costing far more than advertised. It’s crucial to define clear exit conditions upfront: specify the level of skill mastery required before one can stop the program if no job has been secured.

Cost

These short-term courses require tuition fees, though the amount is modest. They also demand a significant time commitment. The challenge lies in knowing when to stop the program if results aren’t evident despite completing part of the coursework, per the agreed terms.

Benefit

Government guidelines align with this approach: they support “private training institutions offering market-driven, high-quality vocational programs and short-term training initiatives that lead to swift employment.” They also encourage vocational colleges to “focus on skills and knowledge in high demand by the job market... and develop micro-specializations and vocational training courses.”

Note

The sole deciding factor is whether a specific job opening exists after completing the program. Programs requiring a year or more of study followed by further “experience accumulation” incur far higher actual costs than their listed price. The exit conditions outlined in Section 4 also apply here: clearly define in advance the skill threshold at which one may discontinue the program if no job is found.

Rereading a section often makes it seem very familiar, but that doesn’t mean you’ve actually retained it well. Testing yourself after reading yields noticeably better results. In classrooms where brief quizzes are added, average test scores rise by a moderate amount. When ranking ten common study methods, self-testing comes out on top. After finishing a section, try writing down the key points from memory before checking them against the text.

Cost

There’s no cost involved, and no extra time is needed. Use the time you’d otherwise spend rereading to write down or answer questions from memory instead. The difficulty lies in how uncomfortable it feels to confront what you’ve forgotten right away, compared to the relative ease of rereading.

Benefit

A meta-analysis of 222 separate studies involving 48478 students found that classroom quizzes led to a moderate improvement in academic performance (effect size g = 0.499). This effect varies depending on several factors: the baseline study method used in the control group, how closely the quiz format matches the final exam, whether the material is comparable, whether corrective feedback is provided, how many times the quiz is administered, when and where it takes place, how long the intervention lasts, and the experimental design used. Another comprehensive review that evaluated all ten widely used study techniques rated “practice testing” and “spaced practice” as the most effective methods overall. Their high utility stems from proven success across learners of different ages and abilities, as well as in diverse testing formats and real-world educational settings.

Note

Self-testing is meant to force information out of your memory, not to assign grades. The recommended approach is to write down key points from memory after reading a section, then check them against the text. Providing corrective feedback further boosts effectiveness, so it’s important to carefully review why each answer was incorrect. The “large” magnitude of benefit mentioned here is determined by both the effect size and the overall rating. Since these studies measured academic outcomes rather than time saved, they weren’t evaluated against time‑saving thresholds. Self-testing and the method described in item 15 — spreading the same amount of study time across several days — are the two highest‑rated strategies identified in the same review; using them together yields the best results.

Studying the same amount of material over several days helps you retain it far better than cramming it all at once. 317 separate experiments have all confirmed this same conclusion. There’s also a practical rule to follow: the longer you want to retain the information, the longer the interval between review sessions should be. If a test is tomorrow, review the material that day; if it’s a month away, schedule a few review sessions in between.

Cost

There’s no extra expense, and the total time required stays the same. The only change is the schedule: those same 3 hours are split into three 1-hour sessions. The challenge is that you must start planning days in advance — you can’t leave it all for the final night.

Benefit

This is a meta-analysis that brought together data from 184 papers, 317 experiments, and 839 separate evaluations of distributed practice. It compared two key factors: studying material in one continuous block versus splitting it into multiple sessions (the spacing effect), and short versus long review intervals (the delay effect). Its main finding is that both the length of time you aim to retain information and the spacing between review sessions together determine your final retention rate: the longer you need to remember the material, the longer the ideal spacing between reviews becomes. Another review that assessed ten common learning strategies ranked distributed practice as one of the highest utility methods overall.

Note

This tip works best when combined with Tip 14 (self-testing without looking at notes): you can also spread out those self-test sessions over several days. Most of the study materials used in Cepeda’s meta-analysis focused on simple tasks like memorizing word lists, so no universal recommended interval length exists for more complex subjects. The original research states that the longer the upcoming test date, the longer the ideal spacing between reviews should be, but no specific schedule is provided. Cramming the night before an exam does offer some short-term benefit, but the information is quickly forgotten.

Highlighting and rereading are the most common study habits among students, yet both rank at the very bottom among ten widely used learning strategies. Summarizing, keyword memorization, and visualizing text with images also fall into the lowest tier. They’re not completely useless, but only work under very specific conditions, so spending the same amount of time on self-testing yields far better results.

Cost

No cost at all; actually saves time. These methods are easy to apply and give you that “I’m studying” feeling.

Benefit

This review evaluates ten common study methods based on how well their effectiveness holds across different learning contexts, student traits, materials, and assessment formats. The highest-rated strategies are practice testing and spaced practice. Methods rated as moderately effective include elaborative questioning, self-explanation, and interleaved practice. The five least effective methods are summarizing, highlighting (or underlining), keyword memorization, visualizing text with images, and rereading. The review also notes that while most students report using rereading and highlighting, these methods do not reliably improve academic performance; they should be replaced with other approaches such as practice testing instead of rereading.

Note

You can use highlighting to mark sections you plan to self-test later, but the problem arises when highlighting itself is mistaken for actual learning. The review also clarifies that being in the lowest tier does not mean these methods have zero value — they simply work only under narrow circumstances and require further research. For alternative study actions, see item 14 (self-testing after closing the book) and item 15 (spreading study time across multiple days).

Practicing one type of problem over and over makes it feel easy at the time, but later you might struggle to recall which method to apply. Mixing several types together yields better long‑term results — though the improvement is moderate. This technique works best with visual material such as drawings or categorization tasks; it has a smaller effect on math problems, and for vocabulary memorization it’s actually better to practice in blocks.

Cost

No cost at all. Simply rearrange the order of exercises in your workbook so they’re not grouped by type. The downside is that mixing them often lowers your immediate accuracy, which can feel like a step backward.

Benefit

This finding comes from a comprehensive meta‑analysis that included 59 studies, 238 effect sizes, and 158 samples. Overall, interleaved practice produces a moderate benefit compared with blocked practice (Hedges’ g = 0.42). When broken down by material, visual tasks benefit the most (g = 0.67), while math problems show a smaller effect (g = 0.34). No significant advantage was found for expository texts or taste‑related tasks; for vocabulary, blocked practice actually performed better (g = −0.39). Regression analysis indicates that the benefit grows when categories are more similar, when items within a category are less alike, and when the material itself is more complex.

Note

The review cited in item 16 — which warns against relying solely on highlighting — rated interleaved practice as having a moderate effect, noting that evidence at the time was limited. Taken together, these studies suggest that interleaving works well for material that requires you to recognize a category and pick the right method, such as different math problem types, medical cases, or legal statutes. In contrast, content meant for rote memorization — like vocabulary or definitions — is better learned through blocked practice.

Many people believe each person has a distinct learning style — such as being visual or auditory — and that teaching should be tailored to that style for best results. Yet there are very few rigorous studies on this, and almost none provide any support for it; several even show the opposite. While people do have personal preferences, there’s no evidence that instruction aligned with those preferences leads to better learning. There’s also no need to spend money on learning style assessments.

Cost

No cost at all. You simply stop using this classification to pick materials or courses, and you also avoid spending money on style assessments.

Benefit

A comprehensive review evaluating evidence on learning styles concluded that to prove “teaching according to learning styles” works, students must first be grouped by style, then randomly assigned to different teaching methods, and finally tested using the same assessment. The key indicator of effectiveness would be a specific interaction effect: a teaching method highly effective for one style would be less effective for another. The review found almost no such interaction effects. Although there’s plenty of literature on learning styles, very few studies employ proper experimental designs, and several of those produce results directly contradicting the “match hypothesis.” Based on this, the authors argue current evidence simply doesn’t justify incorporating learning style assessments into educational practice.

Note

The review also notes this doesn’t mean every version of learning style theory has been tested and disproven; many have never been examined at all. What you should definitely avoid is spending money on learning style assessments or selecting training programs based on such classifications. Criteria for picking training options are outlined in item 9 (prioritizing government-subsidized programs) and item 13 (favoring short-term programs that lead directly to employment).

Testing yourself after closing the book offers benefits far beyond rote memorization. Extensive experimental comparisons confirm that practice testing transfers effectively to varied question formats, practical applications, and complex reasoning tasks. However, its benefit diminishes in two scenarios: when question-and-answer pairings are reversed, and when the underlying concepts were merely read without any active retrieval attempt.

Cost

There’s no expense involved, nor does it require extra time. The only change is the practice method: replace “reciting it verbatim” with “creating questions based on future usage.” The real challenge is figuring out exactly how you’ll apply this material later on.

Benefit

This meta-analysis examined over 40 years of research, drawing from 67 published and unpublished papers, 122 experiments, and 192 measures of transfer effects involving 10382 participants total. Compared to simply reviewing material without testing, practice testing led to measurable learning transfer, with an effect size of d = 0.40 (95% CI 0.31–0.50). Transfer was strongest when participants answered questions of a different type, application or reasoning problems, or medical‑diagnosis‑style queries involving similar concepts. Transfer was weakest when the stimulus–response pairing was reversed, when material had only been encountered but never tested, or when dealing with example‑style problems. Factors such as whether the practice and test formats matched, whether detailed feedback was provided, and whether participants answered correctly on the initial test all strongly influenced whether positive transfer occurred. Two separate methods were used to correct for publication bias; while these adjustments modestly affected effect sizes, they substantially lowered the baseline intercept value. Under these conditions, positive transfer is often not observed at all.

Note

The term “memorization” usually bundles two distinct activities: repeatedly reading or highlighting material, and actively recalling it after closing the book. The former receives the lowest rating in a review that ranked ten learning strategies; for those ratings themselves, see item 16 (avoid relying on highlighting, repeated reading, or summarization as primary methods). What matters here is the latter: actively recalling information without looking at the source, as described in item 14 (self‑testing after closing the book). This practice should also be spread across several days, as noted in item 15 (distributed practice). Begin by determining how you’ll ultimately use the material—whether you’ll need to select answers on a test or make judgments in a real‑world setting—and then create questions that mirror those situations. It’s also valuable to reverse the question–answer order during practice, because the meta‑analysis showed that transfer is weakest in that direction; both orientations should be practiced.

There are 27 professional series nationwide, each divided into junior, intermediate, and senior levels. Generally, you must progress through these levels one by one. Employees working for organizations must have their applications reviewed and publicly posted by their employer before submission. Those working for private firms can apply via local professional qualification service centers, talent agencies, or industry associations. Self-employed individuals should apply through the local human resources and social security department.

Cost

No cost involved. It takes about half an hour to look up the latest application guidelines for your province.

Benefit

A total of 27 professional series exist across China, covering fields such as economics, engineering, healthcare, and publishing. These are categorized into senior, intermediate, and junior levels. Order No. 40 issued by the Ministry of Human Resources and Social Security applies to enterprises, public institutions, social organizations, individual economic entities, and self-employed professionals alike. Applicants must generally advance step by step through these levels. Employers must review all submitted materials and publicly display them for at least five working days. Private firms and self-employed individuals may opt to have talent agencies handle the review, public posting, and recommendation processes. Local authorities are required to establish professional qualification service centers in science parks and high-tech zones; applications may also be accepted through talent agencies, industry associations, and professional societies. Eligible self-employed individuals may participate in evaluations organized by local human resources departments. Any documentation that can be verified online must not require additional certification. If any materials are missing, evaluators must clearly specify what is lacking in one single notice. Employees of private firms typically apply in the region where their employment contract is based. Those assigned to work elsewhere for at least one full year may apply at their temporary duty location. Retired personnel are ineligible to apply. Public sector employees currently under disciplinary action at or above the level of a reprimand cannot apply during that period (nationwide).

Note

No single nationwide list of required documents exists. Each professional series and province publishes its own annual application guidelines detailing necessary materials, deadlines, and performance criteria. Therefore, the first step is to search the official website of your provincial human resources department for the current year’s instructions. Publishing academic papers is no longer mandatory: a 2016 reform directive explicitly removed this requirement for practical professionals, and standardized language or computer proficiency tests are no longer mandatory either. Skilled technical workers may also qualify to apply for engineering-related professional titles. Government officials are prohibited from participating in such evaluations.

Many entry- and intermediate-level professional titles are awarded solely through exams; passing the test is enough, with no additional evaluation needed. Accounting falls under this category: an assistant accountant must have at least a high school diploma, while a full accountant requires a bachelor’s degree plus four years of accounting work experience, or an associate degree plus five years. Those who already hold certain professional certifications may also be recognized as meeting the corresponding title requirements.

Cost

Registration fees vary by province. Preparing for the exam requires several months of part-time study.

Benefit

A 2016 reform directive states that for professional fields where entry- and intermediate-level titles rely on a national exam, no further evaluation or certification is required. In areas where professional titles and qualifications are closely linked, earning a qualification automatically grants the corresponding title and can serve as a prerequisite for advancing to a higher level. Accounting is a prime example: assistant accountants and accountants are selected via a nationwide exam. Senior accountants undergo both an exam and evaluation, while top-level titles are awarded solely through evaluation. Qualification criteria are as follows: Assistant accountants must have at least a high school diploma, including vocational, technical, or secondary specialized education. Accountants must hold a doctorate; or a master’s degree plus one year of accounting experience; or a second bachelor’s degree, graduate diploma, or equivalent plus two years of experience; or a bachelor’s degree plus four years of experience; or an associate degree plus five years of experience. Those with a master’s or doctorate in accounting may be exempt from the Financial Management exam portion when applying for accountant status.

Note

To determine whether your professional series relies on exams, evaluations, or a mix of both, consult the relevant “Guiding Opinions on Deepening Reforms of [Series] Professional Title Systems.” These documents were issued by the Ministry of Human Resources and Social Security and sector-specific authorities; they can be found in the policy archives on the Chinese Government website. Exact registration dates and exam subjects are listed in each year’s official exam announcements. Civil servants may take the accounting exam but are not eligible to apply for accounting title evaluations.

Any professional title obtained through fake materials, ghostwritten papers, or plagiarized work will be revoked upon verification. A record of this misconduct stays on file for 3 years and is shared with the national credit database. If you sign a commitment statement during application and later prove it to be false, you will be barred from applying for any title for 3 years. Labor and social security authorities also actively crack down on agents that make false claims, pose as official evaluators, or sell counterfeit certificates.

Cost

No direct monetary cost. The real challenge is resisting tempting ads promising “guaranteed approval for a fee.”

Benefit

As stipulated in Order No. 40 issued by the Ministry of Human Resources and Social Security, anyone found to have submitted false materials, plagiarized others’ work or academic achievements, or obtained a professional title through any other improper means will have their title revoked. This violation is also logged into the professional title evaluation integrity database and shared with the national credit information platform for a 3-year period. The 2024 regulatory guidelines specifically list several prohibited acts by applicants: making false commitments, fabricating personal information, commissioning ghostwritten papers, falsifying work achievements, and seeking special treatment via personal connections. Applicants must sign a personal commitment statement; failure to honor this agreement results in a 3-year ban on all future applications. Labor and social security authorities collaborate with public security, internet regulatory, and market supervision agencies to investigate and penalize agents that run fake websites, make misleading claims, use contract traps, pose as official evaluators, or sell counterfeit certificates. In cases where violations are severe enough to constitute a crime, relevant parties will be handed over to judicial authorities for prosecution (nationwide).

Note

A simple way to tell legitimate evaluations from fraudulent ones: any officially awarded professional title can be verified via the National Professional Title Evaluation Information Query Platform, accessible through the 12333 website, its mobile app, or the official Ministry of Human Resources and Social Security site. Titles issued by unregistered evaluation committees cannot be found in this system at all. Therefore, any agent or service that guarantees “100% approval”, claims you don’t need to attend any evaluation process, or promises you can use a title even if it does not appear in official records is almost certainly untrustworthy. The main beneficiaries of these rules are applicants themselves, as they protect them from the serious consequences of title revocation and a 3-year negative credit record.

Professional titles serve as the basis for hiring, performance reviews, and promotions, but earning a title and actually being assigned to a corresponding post are two different things. In public institutions, titles are usually awarded within a set post‑ratio, and most people who earn them do get hired. Organizations without post‑based management can separate evaluation from hiring; in such cases, earning a title doesn’t guarantee a post or higher pay. When moving to another organization or region, you may need to re‑evaluate or re‑confirm your title.

Cost

No cost at all. Just ask your HR department once.

Benefit

Article 2 of Ministry of Human Resources and Social Security Order No. 40 states that professional title evaluation results are key references for hiring, performance reviews, and promotions of technical professionals. A 2016 reform guideline specifies that public institutions using post‑based management conduct evaluations within their post‑ratio framework, while organizations without such management — as well as professions with broad applicability and emerging occupations — may separate evaluation from hiring. When technical professionals transfer across regions or employers, their titles must be re‑evaluated or confirmed according to administrative authority, unless otherwise stipulated by national regulations (nationwide).

Note

The evidence grade is B because the documents describe how evaluation and hiring relate to each other, but they provide no nationwide figures on how much pay rises after earning a title. What you can do: in public institutions and state‑owned enterprises, ask HR about available post openings and hiring rules; in private firms, ask the owner whether the certificate is recognized and whether it brings a pay increase.

Pursuing a master's degree incurs direct tuition expenses and the opportunity cost of 2 to 3 years of forgone earnings—with forgone earnings usually being the much larger component. In a comprehensive UK study controlling for individual differences, 35-year-old women with master's degrees earned only about 2% more than bachelor's graduates, while men earned approximately 2% less. Law, economics, and business/management graduates gained about a 20% premium, whereas arts, English, and philosophy graduates earned over 10% less. You must evaluate the numbers based on your specific academic discipline.

Cost

Zero monetary cost. Reviewing official enrollment brochures, tuition rates, and comparing them with your existing entry-level job offers takes about 1-2 hours.

Benefit

First, consider direct financial expenses. Under 2013 national educational guidance, standard full-time academic master's degree tuition is capped in principle at 8,000 RMB per academic year. Full-time professional master's degree programs are governed by separate fee regulations and are exempt from this cap, frequently charging significantly higher rates. Enrolled full-time graduate students within official enrollment quotas receive national graduate stipends of at least 6,000 RMB per academic year, with specific rates set locally. Next, examine economic returns. A 2020 UK Department for Education study tracked individuals graduating with bachelor's degrees between the mid-1990s and mid-2000s using longitudinal educational and tax records. After adjusting for socioeconomic background and undergraduate academic performance, researchers evaluated annual earnings at age 35: estimated returns were +2% for women and -2% for men compared to bachelor's degree holders. Disciplinary variance was pronounced: women holding master's degrees in law, economics, and business management earned approximately 20% more, while those in arts, English, and philosophy earned over 10% less. For men, master's degree returns across most fields were noticeably negative, though law, economics, business management, and engineering remained distinctly positive.

Note

Contested / Disputed. Prior UK studies consistently estimated positive returns for master's degrees; the authors of this study argue that more granular tax data and tighter controls for background variables explain the divergence. However, the authors acknowledge inability to control for unobserved factors like intrinsic motivation and career preference. The data only tracks earnings up to age 35 for cohorts graduating 20-30 years ago, and comparable longitudinal domestic datasets controlling for individual confounders are unavailable, serving as directional guidance. Hence the evidence grade is B. The economic calculation mirrors Chapter 23, Rule 6 (further study vs. entering the workforce): compare 2-3 years of forgone wages and tuition against the incremental annual earnings premium expected later. Some public institutions, universities, research academies, and state-owned enterprises explicitly mandate a master's degree in recruitment postings; in these instances, the qualification threshold itself is a non-negotiable prerequisite that must be factored into your evaluation separately.

In the same UK longitudinal study, after controlling for individual differences, 35-year-old female PhD holders earned roughly 8% more than bachelor's graduates, while male PhD holders earned approximately 9% less. Furthermore, the psychological strain of doctoral training is substantial: roughly one in four PhD students across multiple nations exhibits significant depressive symptoms, and one in six reports notable anxiety. Pursuing a PhD is economically and personally justified primarily when your desired career path makes a doctorate an indispensable requirement.

Cost

Zero monetary cost. Check educational prerequisites in job listings for target institutions, and have an in-depth conversation with 2-3 current doctoral candidates.

Benefit

The 2020 UK Department for Education study cited in Rule 24 also evaluated doctoral degree returns: after adjusting for background and academic performance, 35-year-old PhD holders earned +8% (women) and -9% (men) compared to terminal bachelor's graduates. Doctoral degrees reduced the probability of unemployment and earnings below £30,000 per year, but also reduced the probability of earning over £40,000 compared to certain master's cohorts. Returns varied widely across disciplines: returns for mathematics PhDs were exceptionally low, whereas psychology doctorates yielded some of the highest returns. Regarding psychological strain during doctoral studies, a 2021 meta-analysis aggregating 16 studies encompassing 23,469 PhD students identified significant depressive symptoms in approximately 24% of candidates (95% CI: 18%–31%). Across 9 studies covering 15,626 candidates, clinically relevant anxiety was identified in approximately 17% (95% CI: 12%–23%), with substantial heterogeneity across studies (I² ≈ 98%). Domestic financial frameworks follow the 2013 ministerial guidance: standard tuition for full-time academic doctoral students is capped in principle at 10,000 RMB per academic year, with national graduate stipends mandated at not less than 10,000 RMB per academic year.

Note

Contested / Disputed. The pooled depression and anxiety figures aggregate multinational survey samples without matching against same-age non-academic peer cohorts, utilizing varied psychological screening instruments. They indicate that psychological distress is prevalent among doctoral candidates, but do not isolate doctoral enrollment as the sole causal mechanism. Systematic reviews of Chinese doctoral candidates indicate psychological symptoms are comparable between master's and doctoral students, but both groups score higher than national general population and youth norms. Limitations regarding wage returns mirror Rule 24 and serve as directional reference. University faculty positions, research institutes, and specialized R&D roles frequently mandate a doctorate; candidates targeting academia should review recent recruitment notices at target institutions before committing. If persistent depressive symptoms endure for over two weeks during doctoral studies, follow the initial steps outlined in Chapter 3, Rule 18 (steps to take when feeling depressed); if experiencing suicidal thoughts, call 12356 or emergency mental health crisis hotlines immediately, as detailed in Chapter 1, Rule 25.
