How Many Points to get IB Diploma – Pass Requirements

Every year, thousands of IB Diploma Programme (IBDP) students ask the same question in the final months before results day: How many points to get IB Diploma? The honest answer is more layered than a single number, and that layer is exactly where students get caught out. A student can total 27 or even 30 points and still walk away without the diploma.

This guide breaks the requirement down clearly, shows a real worked example of two students with identical scores and different outcomes, and points you toward the areas that matter most if you are cutting it close.

The IB Point Breakdown: Where the 45 Comes From

Your total IB score is built from two separate sources.

Each of your six subjects is graded on a scale of 1 (very poor) to 7 (excellent). Six subjects multiplied by a maximum of 7 gives you 42 points. On top of that, your combined TOK and EE grades (each scored A to E) can add up to 3 further bonus points, based on a fixed grade matrix set by the IBO.

24 Points Is the Minimum, Not the Whole Story

To be awarded the diploma, you need to clear all of the following at the same time, not just one of them:

•       A total score of at least 24 points
•       At least 12 points combined from your HL subjects
•       At least 9 points combined from your SL subjects
•       A grade of D or above in both TOK and the Extended Essay
•       Satisfactory completion of CAS
•       A grade of at least 2 in every subject
•       No more than two grades of 2 across all subjects
•       No more than three grades of 3 or below across all subjects

Miss any single one of these and the diploma is withheld, regardless of how high your total score is. The full list actually runs to eight conditions once you include the caps on how many grade 2s and grade 3s you can carry. We have laid out every one of them, with worked explanations, in our complete IB Diploma failing conditions checklist.

Two Students, Same Total Score, Different Outcome

This is the part most guides skip entirely, and it is usually the part that catches students by surprise. Two students can finish with the exact same total and get opposite results.

Priya and Daniel both finish on 27 points, well above the 24-point minimum. Priya passes because her HL subjects combine to 14 points, clearing the 12-point HL floor. Daniel fails the diploma despite the identical total, because his HL subjects only combine to 10 points, one condition short of the required 12. His higher SL performance cannot compensate for a shortfall at HL level.

This is precisely why subject level strategy, not just overall points, matters so much in the final two years. Our 1-on-1 IB tutoring sessions are built around tracking exactly this kind of HL and SL balance well before results day, not after.

How Many HL and SL Points Do You Actually Need?

Students take a minimum of three and a maximum of four subjects at Higher Level, with the remainder at Standard Level.

•       HL subjects: combined score must reach at least 12 points
•       SL subjects: combined score must reach at least 9 points

If you are taking four HL subjects, only the three highest HL grades count toward this 12-point floor. If you are taking only two SL subjects, at least 5 points combined are required at SL (rather than 9). These details change subject choice strategy for a lot of students, and they are worth reviewing with a tutor if your predicted grades are close to the line.

What Counts as a Good IB Score Beyond the Minimum

Passing and being competitive for university are two different targets. The global average IB score sits around 30 out of 45. For UK university admissions specifically:

•       32 to 36 points is a workable range for most UK universities
•       35+ points is a safer benchmark for Russell Group universities
•       38 to 40+ points, with specific HL grade requirements, is typical for Oxford and Cambridge

For a full university by university breakdown including UCL, Imperial, LSE, and King’s College London, see the requirements table in our IB Diploma Requirements guide.

What Happens If You Miss the 24-Point Minimum

Missing the requirement is not the end of the road. Since 2023, the IBO removed its previous three session limit on retakes, so students are no longer restricted in how many times they can attempt to meet the requirement. Retake sessions run every May and November, and you can retake individual subjects, the TOK essay, or the Extended Essay without repeating the entire two year programme.

If your predicted grades suggest you are close to the threshold, targeted preparation before the next session matters far more than broad, unfocused revision. Our Rapid Revision and IB Exam Retakes course is built specifically for students working against this exact deadline.

IB Diploma vs Career-related Programme: A Different Passing Standard

Most guides on this topic only discuss the IB Diploma Programme (DP), but the IBO also runs the IB Career-related Programme (CP), and its passing structure is different. CP students combine two or more DP subjects with a career-related study and a core built around a reflective project, service learning, language development, and personal and professional skills. There is no single 45 point scale in the CP. Instead, students must pass their DP subject components and their career-related course requirements separately, and the core is assessed on a completion basis rather than contributing bonus points. If you are unsure which pathway you are enrolled in, check with your school coordinator, since the point based rules in this guide apply specifically to the Diploma Programme.
