What Are the IB Exam Passing Requirements? A Simple Guide

To earn the IB Diploma, a student must achieve at least 24 points overall, including at least 12 points across Higher Level (HL) subjects and 9 points across Standard Level (SL) subjects. Students must also complete CAS and achieve no grade E in Theory of Knowledge (TOK) or the Extended Essay (EE). Other conditions, including limits on low subject grades, also apply.

So, what is the IB exam? It is the final assessment of the IB Diploma Programme, sat at the end of grade 12 across six subjects plus the core. It combines internal assessment, coursework marked at school and moderated by the IB, with external examinations set and marked by IB examiners each May or November. The weighting of internal assessment and external examinations varies by subject. The IB explains how these components are assessed and weighted on its IB Diploma Programme page. A student's final IB result is based on this combined assessment, not the exam alone, which is why two students with similar exam performance can still end up with different final results.
Unlike a single board exam with one pass mark, the IB exam is really a basket of assessments spread across two years. Internal assessment typically accounts for 20 to 30 percent of a subject's final grade, with written examinations covering the rest, so consistent classwork matters as much as exam-day performance.

Each of the six DP subjects is graded on a scale of 1 to 7, so six subjects can earn up to 42 points. A further 3 core points come from the combined performance in Theory of Knowledge and the Extended Essay, taking the maximum possible score to 45.

These are the core IB diploma requirements a student must clear, all at once, to be awarded the diploma rather than just a course certificate:

· A minimum total of 24 points out of 45.

· At least 12 points combined across higher level (HL) subjects.

· At least 9 points combined across standard level (SL) subjects, or 5 points if only two SL subjects were taken.

· No more than three grades of 3 or below across all six subjects.

· No more than two grades of 2 across all six subjects.

· No grade of 1 in any subject.

· A combined grade of at least D in Theory of Knowledge and the Extended Essay together.

· Full completion of the Creativity, Activity, Service (CAS) requirement.

If any single condition above is not met, even with a high points total, the IB awards a course results certificate instead of the full diploma. This still records the subject grades achieved and is accepted by many universities, but it does not carry the same recognition as the diploma itself.

Students who narrowly miss the requirements can request a re-mark of specific components or, in later sessions, retake individual subjects to improve their total. Schools guide this process closely, since deadlines for re-marks and retakes are short.

Meeting IB diploma requirements is rarely about one big push in grade 12; it comes down to a few habits tracked consistently across both years of the programme.

· Review projected grades against the 24-point and grade-limit thresholds each term, not just before mock exams.

· Log CAS hours and reflections as they happen rather than backfilling them close to the deadline, since incomplete CAS blocks the diploma regardless of subject scores.

· Treat the Extended Essay and TOK essay as a combined score, not two separate boxes to tick, since a weak grade in either drags the joint result down.

· Flag a subject sitting at or below a 3 early, so there is time to close the gap before it becomes one of the three allowed low grades.

Universities in India and abroad generally ask for the full IB Diploma, not just strong subject grades, because the diploma confirms a student cleared all the IB requirements together, including CAS and the TOK-Extended Essay combination. A course results certificate can still support an application in some cases, but most competitive programmes list the diploma itself as a condition of offer.

This is one reason IB requirements are worth tracking well before grade 12 begins. A student who is strong in HL subjects but behind on CAS hours, for instance, is at real risk of missing the diploma even with a comfortable points total, since CAS completion is a pass or fail condition on its own, separate from the 45-point scale.

Tracking IB requirements against real projected grades, not just end-of-year reports, makes the difference between a comfortable pass and a last-minute scramble. Start the IB admissions process in Chennai to see how we track every DP student's progress against these exact thresholds, two years out.

The IB diploma requirements are demanding on purpose. They are built to reward balance across HL and SL subjects, not just one strong result carrying the rest. Understanding these thresholds early, from grade 11 onward, gives students and parents a realistic picture of where extra support is genuinely needed.
