CLEP exams (College Level Examination Program) allow students to earn college credit for knowledge they already have by passing a standardized test — without taking the course. The College Board offers 34 CLEP exams across five subject areas: History and Social Sciences, Composition and Literature, Science and Mathematics, Business, and World Languages. Each CLEP exam costs $93 (plus a testing center fee of approximately $20–$30). A passing score on a CLEP exam typically earns 3–12 college credits at institutions that accept CLEP scores. Over 2,900 colleges and universities accept CLEP credit. This guide covers all 34 CLEP exam subjects, how CLEP works, cost, registration, and how to prepare in 2025–2026.
CLEP exams test college-level knowledge that students may have acquired through self-study, work experience, military training, or prior coursework that did not result in credit. Passing a CLEP exam at the required score earns college credits equivalent to completing the corresponding introductory-level college course.
The CLEP exam process:
CLEP scoring: CLEP exams are scored on a 20–80 scale. A score of 50 is the standard passing threshold recommended by the American Council on Education (ACE) and required by most colleges. Higher scores are not universally required, but some selective institutions require 60+ for credit.
The College Board offers 34 CLEP exams organized into five subject areas. Each exam corresponds to one or more introductory college courses.
History and Social Sciences (9 exams):
Composition and Literature (5 exams):
Science and Mathematics (7 exams):
Business (5 exams):
World Languages (8 exams):
Over 2,900 colleges and universities accept CLEP credit — but policies vary significantly. Checking your specific college's CLEP policy before registering is essential.
Types of CLEP credit policies:
Military CLEP benefits: All active-duty US military service members can take CLEP exams for free through the Defense Activity for Non-Traditional Education Support (DANTES). The Department of Defense funds all CLEP fees for eligible service members, making CLEP an extremely cost-effective way for military personnel to earn college credits while serving.
How to find college CLEP policies: The College Board maintains a searchable database of college CLEP policies at clep.collegeboard.org/score-information/institution-search. Search your college to see which CLEP exams they accept, the minimum required score, and credits awarded. Policies update annually — verify the current policy at the admissions or registrar's office of your specific college.
Maximum CLEP credits: Many colleges limit the total number of credits you can earn through CLEP and other credit-by-examination programs. Typical limits range from 30–45 credits. Check your college's credit-by-examination policy for limits that apply to your degree program.
CLEP exam preparation depends heavily on your existing knowledge. Students with strong background in a subject can pass with 2–4 weeks of focused review; students starting from scratch may need 6–12 weeks of intensive study.
Study resources by approach:
Which CLEP exams are easiest to pass: Pass rates vary significantly by subject. History and Social Sciences exams (Principles of Management, Introduction to Business Law) generally have higher pass rates than Science and Mathematics exams. Biology and Chemistry have lower pass rates — more preparation is typically required. Choose subjects where your background gives you a realistic advantage.
