Best Pre-Law Majors 2026: What to Study Before Law School
The American Bar Association does not require a specific major for law school admission. But not all majors produce equal LSAT performance, and the choice affects both your GPA and your applicant differentiation. The data below comes from LSAC published statistics on LSAT performance by major.
The Key Insight
There is no required major for law school. The ABA explicitly does not recommend any specific undergraduate path. Choose based on (1) your genuine interest, (2) where you can achieve the highest GPA, and (3) what skills you want to build. GPA matters more than major prestige in the admissions formula. The data below shows that the most popular pre-law major (political science) does not produce the strongest LSAT results.
LSAT performance by undergraduate major
LSAC publishes annual data on LSAT scores by undergraduate major. The table below shows the average LSAT score by major and the approximate number of LSAT takers per cycle from each. Sample sizes for less common majors are smaller; treat differences within 1.5 points as within statistical noise.
| Undergraduate Major | Avg. LSAT | Approx. Test Takers / Year | Notes |
|---|---|---|---|
| Physics / Mathematics | 160.2 | 1,100 | Consistently highest LSAT averages. Logic-heavy training transfers directly. |
| Philosophy / Religion | 159.5 | 2,800 | Strong logic and writing emphasis. Most successful niche pre-law track. |
| Economics | 158.5 | 5,200 | Quantitative analysis plus some legal-adjacent topics. Strong consistent track record. |
| Engineering | 157.6 | 1,800 | Analytical strength; lower verbal scores can pull average down. |
| Chemistry / Biology | 156.6 | 2,400 | Patent law track is strong; LSAT averages slightly above national mean. |
| International Relations | 156.4 | 2,200 | Strong reading-heavy preparation; competitive applicants. |
| English / Literature | 155.8 | 4,100 | Reading and writing focus aligns well with LSAT skills. |
| History | 155.5 | 4,800 | Reading-intensive; common pre-law major with consistent results. |
| Political Science / Government | 153.8 | 18,000 | Most common pre-law major. Average LSAT slightly below national mean. |
| Psychology | 153.0 | 4,900 | Common pre-law major; LSAT averages near national mean. |
| Sociology | 152.8 | 2,200 | Common pre-law major with average LSAT outcomes. |
| Communications / Journalism | 151.9 | 2,900 | Below-average LSAT outcomes; can be offset by strong writing skill. |
| Business / Marketing | 151.5 | 5,800 | Less analytical preparation; below-average LSAT averages. |
| Criminal Justice | 146.8 | 2,500 | Lowest average LSAT among common pre-law majors despite topical relevance. |

What this data means for major choice
Three patterns emerge from the LSAC data and they challenge conventional pre-law advice:
- Political science is not the highest-performing major. Despite being the most common pre-law major (about 18,000 LSAT takers per cycle), political science majors post LSAT averages slightly below the national mean. The major is over-represented because it intuitively connects to law, not because it produces stronger applicants.
- Quantitative and logic-heavy majors outperform. Philosophy (159.5), economics (158.5), physics (160.2), and engineering (157.6) majors consistently post stronger LSAT averages than the popular humanities pre-law tracks. The selection effect (students attracted to these majors are already comfortable with abstract reasoning) is real, but the curricular preparation matters too.
- Criminal justice is among the weakest majors for LSAT performance, with averages 6 to 8 points below the strongest majors. The topical relevance of criminal justice does not translate into LSAT skill. Applicants drawn to criminal law for career reasons should consider another major and add criminal justice courses for content depth.
The skills that actually matter
Major matters less than what specific skills your courses build. The LSAT and 1L year both reward four core competencies:
Critical reading at speed
The LSAT and law school both reward reading complex argumentative text quickly and accurately. Every major can develop this skill, but it is most heavily exercised in philosophy, history, English, classics, and rigorous social sciences.
Analytical writing
Argument-based writing with clear logical structure. Philosophy, English, history, and political science assign it most often. STEM majors who add 4 to 6 writing-intensive humanities courses can match this preparation.
Logical reasoning
Identifying valid versus invalid inferences, assumptions, and argument structures. Philosophy formal logic courses, mathematics proof-based courses, and computer science develop this most directly.
Research methodology
Identifying credible sources, organizing evidence, and constructing arguments from data. Most majors develop this; quality varies more by program rigor than by major.
Pre-law programs and advising
Formal pre-law program / minor
Many universities offer pre-law minors or advising programs. These are useful for advising and community but do not affect law school admission. Schools do not weight 'pre-law' as a major because it is not a formal degree.
Joint 3+3 accelerated programs
About 60 ABA-accredited law schools partner with undergraduate institutions for 3+3 programs that complete bachelor's plus JD in 6 years. Useful for applicants certain about law school by sophomore year. Less useful if you might change directions.
Pre-law internships
Summer internships at firms, courts, or legal nonprofits add resume substance and confirm interest. Most pre-law programs help facilitate placements. Internships matter for personal statement material more than for admissions weighting.
Mock trial / debate
Active participation demonstrates argumentation skill and comfort with structured advocacy. Common across pre-law applicants but adds dimension only when you held leadership positions or competed at high levels.
Recommended courses regardless of major
A few specific courses materially help LSAT preparation and 1L readiness regardless of your major:
- Symbolic or formal logic: Most directly relevant to LSAT logical reasoning. Taken in philosophy or mathematics departments.
- Statistics or quantitative methods: Useful for evaluating empirical legal scholarship and for legal practice areas involving regulatory analysis or economics.
- Upper-level writing-intensive seminar: Sustained argumentative writing under faculty review. Builds the foundation for legal writing.
- Constitutional law (undergraduate): If offered. Provides foundational knowledge useful for 1L year.
- Microeconomics: Lawyers regularly engage with economic frameworks; this single course pays dividends across many practice areas.
- Ethics or political philosophy: Builds skill in normative reasoning, which appears in nearly every law school class.
Frequently asked questions
Do you need a specific major to apply to law school?
›
No. The American Bar Association Standards 502(a) require a bachelor's degree from a regionally accredited institution but specify no major. Law schools admit students from every academic discipline. The ABA explicitly does not endorse a 'pre-law' major. Choose based on your interests and the major where you can earn the highest GPA.
What is the best major for law school admission?
›
If 'best' means highest LSAT performance, philosophy, mathematics, physics, and economics majors consistently post the strongest averages. If 'best' means easiest path to a high GPA, varies by institution and your strengths. Practically: choose a major you can excel in. A 3.85 in any major outperforms a 3.4 in a 'rigorous' major in the admissions formula.
Why do philosophy majors do so well on the LSAT?
›
Philosophy curriculum trains logical inference, argument analysis, and dense reading at depth. The LSAT rewards exactly these skills. The selection effect also matters: students attracted to philosophy are typically already comfortable with abstract reasoning, which the LSAT measures. Pre-law philosophy minors achieve much of the LSAT preparation benefit by adding 4 to 6 logic and ethics courses.
Should I major in political science to go to law school?
›
Political science is the most common pre-law major; this also makes it the most generic application profile. Average LSAT scores from political science majors are slightly below the national mean. Major in political science if you genuinely enjoy it. If you are picking it because it 'goes with law school,' consider whether another major you enjoy would produce better outcomes (higher GPA, distinct application angle).
Is a STEM degree useful for law school?
›
Useful but not strictly necessary. STEM majors post above-average LSAT scores. Patent law specifically requires a STEM background to sit for the Patent Bar. STEM majors also stand out in admissions pools dominated by political science, history, and English. The cost: STEM GPAs are often 0.15 to 0.30 points lower than humanities GPAs, which the admissions formula does not adjust for.
What undergraduate courses help most regardless of major?
›
Symbolic logic or formal logic, statistics or quantitative methods, an upper-level writing-intensive seminar, constitutional law (if offered), and a course requiring sustained research and argumentation. Add 1 to 2 courses in microeconomics; lawyers regularly engage with economic analysis. None of these are required; all materially improve LSAT preparation and 1L readiness.
Does it matter where I get my undergraduate degree for law school admission?
›
Marginally. Law schools see your undergraduate institution but do not formally weight prestige. They evaluate your CAS GPA, LSAT, and application materials primarily. Anecdotally, GPAs from very competitive undergraduate institutions are sometimes read more favorably; the effect is small and variable. The much larger factor is your performance: a 3.8 from a state university outweighs a 3.3 from an Ivy at every law school admissions desk.
