A score below 24 in the IB Diploma means the Diploma itself is not awarded. The IB calls this "failing the Diploma," and the language is harsh. But it does not mean the student has nothing. Individual subjects scored above the minimum still earn IB Certificates, which universities and employers can read. Retake options are available. Many students who score below 24 in their first sitting either retake and pass, or move into a different post-16 route that suits them better.
This guide explains exactly what falls under "below 24," what the student keeps, what the retake process looks like, and what universities will accept. For the underlying point system: what the IB Diploma is and what is a good IB score.
What Below 24 Actually Means
The IB Diploma is awarded only if all of these conditions are met:
Total score of at least 24 points (out of 45, including TOK/EE bonus).
No grade below 3 in any subject.
No more than two grades of 2.
No more than three grades of 3 or below.
At least 12 points across the three HL subjects.
At least 9 points across the three SL subjects.
Satisfactory completion of TOK, EE and CAS — no D or E in either TOK or the EE.
A student who misses any of these conditions does not receive the Diploma. The most common patterns: total under 24 (raw point shortfall), or one of the structural fail conditions (a grade 2 in a subject, weak HL total, D in TOK or EE).
What You Still Get — IB Certificates
Students who do not receive the Diploma still receive an IB Certificate for each subject in which they earned a grade. The certificates are official IB documents and are recognised by universities and employers. They include the subject, the level (HL or SL), and the grade.
If TOK and the EE were completed (regardless of grade) those are also recorded. CAS completion is noted separately.
So a student who scored, say, 22 points but had three good HL subjects (6, 6, 5) walks away with three IB Certificates for those subjects at HL — and those certificates are individually meaningful for some universities and progression routes.
Retake Options
The IB offers two retake routes:
Retake individual subjects. Students can retake up to two subjects in either the May/June or November sittings. There is a one-year limit on retakes (the retake session must be within one year of the original session).
Retake the full Diploma. Students can re-sit the entire Diploma — all six subjects plus TOK/EE/CAS — in a subsequent session, typically the following May/June.
Most students who score below 24 because of one or two weak subjects opt for the targeted retake — fewer subjects, focused preparation. Full Diploma retakes are rarer and usually only happen when multiple subjects need work.
Retake registration is through the original IB school (or a special arrangement with the IB if the student has moved). Registration deadlines are typically 4-6 months before the retake session.
University Routes Without the Diploma
Below-24 doesn't close every university door. Realistic routes:
Foundation programmes. Most UK and Australian universities offer International Foundation Year programmes — one-year university entry programmes accepting students with mixed IB Certificates or below-Diploma results.
Universities accepting IB Certificates. Some universities accept students with individual IB Certificates in specific subjects, especially when accompanied by a strong SAT, IELTS or other supporting evidence.
Less selective universities and colleges. Universities below the top tier sometimes accept students with below-24 IB scores into specific programmes, particularly if the student's HL subjects align with the course.
Defer and retake. Apply to universities in the next admissions cycle after a successful retake. This is the cleanest route if the gap is closeable.
Switch to A-Levels. Possible for students who have a clear academic ability but the IB structure didn't suit. Most international and UK sixth forms can absorb a student from an IB background into A-Levels, though a fresh year is usually required.
What To Do In The Two Weeks After Results
Read the breakdown. Which subjects scored what. Which structural condition triggered the fail (if it's structural rather than raw points).
Talk to the IB coordinator at the school. They have seen this pattern before and know the local retake registration process.
Decide retake vs alternative route. If the gap is one or two grades in subjects the student can re-prepare in 4-6 months, the targeted retake is usually the right call. If the gap is larger, an alternative route may be cleaner.
If applying through UCAS Clearing (UK universities) — Clearing opens on results day and stays open through August/September. Universities with capacity will accept lower scores than published.
If targeting US universities — communicate the actual IB outcome to admissions offices where the student has applied; many will reconsider based on the full profile.
Preventing The Gap In Advance
For students still in the IB programme, the structural fail conditions to watch:
HL subject below 3. A single very weak HL subject can trigger the HL total fail condition (under 12 across three HLs).
TOK or EE at D or E. One D in TOK or EE triggers a fail condition regardless of subject grades. Treat TOK and EE as serious work, not afterthoughts.
Multiple 2s or 3s across subjects. The "no more than two 2s" and "no more than three 3-or-belows" rules are strict.
For ongoing IB students, our IB Diploma tutoring page lists the subjects we cover at HL and SL plus TOK/EE supervision.

Below 24 means the IB Diploma is not awarded. Students still receive IB Certificates for individual subjects in which they earned a grade. They can retake up to two subjects within a year, or retake the full Diploma in a subsequent session. University routes remain available through foundation programmes, less selective universities accepting IB Certificates, or deferring after a successful retake.
Yes. Students can retake up to two subjects in the May/June or November sittings within one year of their original session. Registration is through the original school. Most students who score below 24 because of one or two weak subjects opt for targeted retakes. Full Diploma retakes are also possible but less common.
Some do. UK and Australian universities offer International Foundation Year programmes that accept students with mixed IB Certificates or below-Diploma scores. Less selective universities sometimes accept individual IB Certificates in specific subjects. UCAS Clearing (UK) on results day often finds places at universities with capacity. US universities sometimes reconsider applications when the full profile is presented honestly.
The IB Certificate is an official IB document awarded for individual subjects to students who do not earn the full Diploma. It records the subject, level (HL or SL), and grade. Universities and employers recognise IB Certificates, especially when combined with strong subject grades and other supporting evidence.
Yes. Most UK and international sixth forms can absorb a student from an IB background into A-Levels. A fresh year is usually required — A-Level Year 12 — because the A-Level content overlaps with but is not identical to IB HL. Schools assess the student's IB background to decide the start point.
About 80% of IB Diploma candidates worldwide earn the full Diploma each year. The remaining 20% either fall short on points (below 24), trigger a structural fail condition (HL total under 12, D in TOK/EE, multiple 2s), or do not complete one of the requirements. Failing is not rare but is also not the majority outcome.
