How to Earn College Credit While Still in High School
By Admissions Narrative · · MIT Alumni Admissions Interviewer
Key Takeaways
AP exams (scores of 3–5), IB HL exams (scores of 6–7), dual enrollment courses, and CLEP exams all can earn college credit
AP and IB credits are most universally accepted; dual enrollment transfers most reliably to in-state public universities
Elite schools like MIT and Princeton accept very limited credit regardless of AP or IB scores
Earning credit in high school can save significant tuition and allow early graduation or a double major
Always verify each target school's specific credit policy before assuming credits will transfer
High school students can earn college credit through four main pathways: AP exams (scores of 3–5), IB Higher Level exams (scores of 6–7), dual enrollment courses at community colleges or universities, and CLEP exams. AP is the most universally accepted; dual enrollment credit transfers most reliably within the same state's public university system. Always check each target school's specific policy before counting on credit transfer.
Earning college credit in high school is one of the most financially valuable academic strategies available to families — but it only pays off when you understand which credits will actually transfer to your target schools.
AP Exams
Advanced Placement exams administered by College Board are the most widely accepted source of high school college credit in the United States. Over 4,000 institutions grant credit for AP scores. Scoring 3, 4, or 5 (the required score varies by school and subject) earns credit at most colleges. The specific amount of credit awarded also varies. Check each school's AP credit policy on their registrar website — do not assume a 4 or 5 automatically earns credit everywhere.
IB Higher Level Exams
International Baccalaureate Higher Level (HL) exam scores of 6 or 7 earn college credit at many universities, often comparably to AP. Some schools grant more credit for IB HL than for AP 5s. Standard Level (SL) scores may earn limited credit at some schools. Check each school's IB credit policy specifically.
Dual Enrollment
Dual enrollment courses earn both high school and college credit simultaneously. These credits transfer most reliably to in-state public universities within the same state system. Private college acceptance is more variable — some selective schools do not count dual enrollment credits toward degree requirements. Crucially: dual enrollment grades become part of your permanent college academic transcript, which follows you to graduate school applications.
CLEP Exams
College-Level Examination Program (CLEP) exams allow you to demonstrate college-level mastery by passing a one-time standardized test. Scores of 50 or above earn credit at over 2,900 colleges. Particularly useful for introductory-level requirements and foreign language proficiency. CLEP exams cost $93 each — significantly less than a college course.

How many college credits can you earn in high school?
There is no official cap. Students who take many AP exams with high scores and multiple dual enrollment courses could potentially enter college with 30–40+ credits at schools with generous policies — potentially allowing graduation in three years or adding a double major.
Do all colleges accept AP credits for graduation requirements?
No — policies vary significantly. MIT and Princeton accept very limited AP credit regardless of score, often only for advanced placement rather than credit toward graduation. Always check the specific credit policy for each school and each subject on the registrar's website.
