AP Credit at Stanford University
Score requirements, the 45-unit cap, and credit policies for AP exams at Stanford.
Last updated: · Based on Stanford's published policies
Stanford's AP credit policy is moderate among elite private universities — more generous than Harvard or MIT, but with meaningful restrictions. Stanford operates on a quarter system, so AP credits are measured in quarter units rather than semester hours. The 45-unit cap on combined AP and transfer credit, along with the inability to use AP credit for most General Education requirements, limits how much AP credit you can actually apply toward your degree.
AP Score Requirements at Stanford
Most subjects require a score of 4 or 5, with some departments accepting 3s. Credit amounts vary by exam and score:
| AP Exam | Score Required | Quarter Units |
|---|---|---|

| AP Calculus BC | 4-5 | Up to 10 units |

Placement vs. Credit at Stanford
Stanford offers both credit and placement, but AP credit cannot satisfy most General Education requirements. The only exception is the Foreign Language requirement, which can be met with qualifying AP language scores. For all other Gen Ed areas, you must complete Stanford courses. AP credit works best as elective credit or for advancing to higher-level courses. If you enroll in the Stanford course that duplicates your AP credit, the test credit is removed from your record.
Maximum Credits and Restrictions
The 45 quarter unit cap includes both AP credit and any transfer coursework. No single AP exam can earn more than 10 quarter units. Students who took many AP exams and also have transfer credit should plan carefully to avoid hitting the cap. Since AP credit cannot satisfy Gen Ed requirements, its primary value is as elective credit or for meeting prerequisites in your major. The duplicate course rule means you must decide early whether to use your AP credit or retake the course at Stanford.
How to Send AP Scores to Stanford
