AP or IB: How the Two Programmes Differ
AP and the IB are often mentioned together, but they are built differently. AP is a set of individual College Board courses, each ending in one exam in May; the IB Diploma is a two-year programme of six subjects and a compulsory core. This page sets out the official facts side by side, explains how universities use each, and shows how students combine them.

AP and the IB side by side
AP figures are College Board’s for the 2027 exams; IB figures are the International Baccalaureate’s for the Diploma Programme.
| Criterion | AP | IB |
|---|---|---|
| Run by | College Board | International Baccalaureate (IB) |
| What students take | Individual courses, each ending in its own exam; students choose which and how many | The full Diploma, six subjects and the core over two years, or individual Diploma Programme courses where the school allows |
| Levels | One level per course | Higher Level and Standard Level |
| Scoring | Each exam scored 1–5 | Each subject graded 1–7; the Diploma is out of 45 and awarded from 24 points, subject to further conditions |
| Exam timing | Every May: 3–7 and 10–14 May 2027, with late testing 17–21 May 2027 | The May or November session, at the end of the course |
| Assessment | Mainly the May exam, usually with multiple-choice and free-response sections; a few courses also score work done during the year | Final exams in most subjects, plus internal assessment marked by teachers and moderated by the IB |
| Compulsory core | None | For the Diploma: Theory of Knowledge, the Extended Essay and Creativity, Activity, Service |
| Who can take it | Any student who can sit the exam at a school that administers it; the course is recommended but not required | Students at schools the IB has authorised to teach the programme |
| Registration | Exams are ordered by a school’s AP coordinator, not by the student | Through the student’s own IB school |
| Example offer: University of Cambridge | At least five AP scores of 5, in subjects relevant to the course, usually with high marks in the school qualification and a high SAT or ACT score | Minimum 41–42 points, with 7, 7, 6 in the Higher Level subjects |
| Credit at US colleges | Many US colleges give credit or placement for scores of 3 and above; each college sets its own policy | Each university sets its own policy for IB results |

Who each tends to suit
AP often suits
Students in American-curriculum schools, and students who want to show college-level work in particular subjects without taking on a whole programme. AP lets a student go deep in the subjects that matter for a planned degree and add exams year by year.
The IB Diploma often suits
Students who want a broad, structured two-year programme that keeps languages, sciences, mathematics and the humanities together, and who are comfortable with coursework deadlines and the extended writing the core requires.
Combining both may suit
IB students who want an extra exam in a subject outside their six, or a US-recognised score in a subject they already study. This works only if the extra exam does not crowd out IB deadlines.
Taking AP exams alongside the IB
Students do not need to be on an AP course to sit an AP exam. College Board recommends the course but does not require it, so an IB student can take an AP exam in a subject they study, provided a school that administers AP exams orders it for them through its AP coordinator.
The two exam calendars overlap in May. College Board lists a conflict with an IB exam among the accepted reasons for late testing without an additional fee; the AP coordinator orders the late exam, which is an alternate version of the regular one. Course content overlaps only in part, so an IB student preparing for an AP exam should work from that exam’s official course and exam description, not from the IB guide alone.
How universities treat AP and the IB
In the United States, many colleges grant credit or advanced placement for AP scores of 3 and above. Each college decides which scores it accepts and for what, and IB results are treated under each university’s own policy as well.
Outside the US, requirements are set university by university. The University of Cambridge, for example, asks AP applicants for at least five AP scores of 5 in relevant subjects, usually within a two-year period, and usually also high marks in the school qualification, such as a high school diploma, and a high SAT or ACT score. For the IB Diploma its minimum offers are 41–42 points, with 7, 7, 6 in the Higher Level subjects. The IB keeps a database of the recognition policies universities have shared with it.
How to decide
Start from your school
Most students follow the programme their school teaches. If your school offers the IB, the question is usually whether to add an AP exam; if it offers AP, it is which courses to take and when.
Check your target universities
Read how each university on your list treats AP scores and IB results, for admission and for credit. Requirements differ widely between countries and between universities.
Match the exams to your degree
Choose AP subjects, or IB Higher Level subjects, that line up with the degree you want. Some universities, Cambridge among them, ask for exams in subjects relevant to the course you apply for.
Plan the May calendar
If you will sit AP and IB exams in the same May, set out both timetables early and speak to your coordinators about any clash before exams are ordered.
