IB retakes: the complete 2026-2027 guide

An IB retake is a new attempt at one or more Diploma Programme or Career-related Programme subjects in a later examination session. The difficult part is rarely deciding that you want another attempt. It is working out exactly what must change, finding a school willing to register you, and fitting the new result around university deadlines.

You may retake an IB subject in a future session through an IB World School that offers the relevant programme and agrees to register you. The IB uses the highest grade achieved for the subject. A school is not obliged to accept external candidates, so eligibility and finding a host school are separate questions.

What counts as an IB retake?

A retake means entering a subject again in a later examination session. Students also search for IB resits, retake IB exams, IB exam retakes and retakes IB; in practical terms, they are usually asking about the same new exam attempt.

You do not normally have to repeat the entire Diploma. A targeted retake can focus on the subject or subjects blocking the Diploma, a university offer, a scholarship threshold or a prerequisite. First calculate the exact outcome you need rather than assuming that every lower grade must be repeated.

Who can retake IB exams?

The IB says a Diploma Programme or Career-related Programme candidate can retake a subject in any future examination session at an IB World School offering the programme. Course candidates can also retake. Your former school may help, but it is not required to accept you again.

If you register through another school, that school becomes responsible for the official entry and exam administration. It may limit external candidates by subject, level, session, capacity or internal deadline. That is why a student can be eligible under IB rules but still need a serious host-school search.

How many times can you retake and which grade counts?

The current IB retaking examinations page does not state a fixed three-session limit. Practical limits still exist because a school must accept the entry, the subject must be available and curriculum changes can affect what you study.

The highest grade achieved for a retaken subject contributes to the Diploma. That does not mean every new sitting is low-risk: another attempt costs time and money, and a syllabus change may require preparation for the current curriculum rather than the one you first studied.

May or November: choosing the retake session

May and November are not interchangeable. Subject availability, school participation, travel, revision time and the date universities receive the result can all differ. A November result is normally released in January; that may help one admission route and miss another.

Use the official IB examination schedule to check the exam window, then ask the accepting school for its internal registration cutoff. School cutoffs can arrive well before the examination session, and waiting for a public deadline can leave no time to find a place.

Remark first, retake first, or both in parallel?

A remark, formally an Enquiry Upon Results, reviews work already assessed. A retake gives you a new exam attempt. If you are very close to the next boundary, ask your coordinator about the appropriate EUR category, the possibility of a grade moving down, the fee and the school deadline.

When the gap is larger or the university deadline is tight, it can be sensible to investigate a retake while the remark decision is still pending. Starting a host-school search does not force you to sit the exam; it protects time while you compare the two routes.

Finding a host school and registering

The host school is more than an exam room. It checks your previous record, creates or updates the candidate entry, confirms subjects and levels, receives official exam materials, supervises the papers and communicates local instructions.

Send one complete request: legal name, date of birth, candidate number if available, previous school, latest results, subjects and levels, target session, current location, countries you can travel to and any university deadline. A vague message such as 'I need an IB retake' gives a coordinator too little to assess.

What happens to IA, TOK, EE and CAS?

Do not assume that every internal component can be rewritten. The IB advises candidates to discuss whether to retake examinations or submit new or revised non-examination components with the school coordinator. The answer depends on the component, candidate history and current regulations.

If the Diploma was not awarded because of a core condition, identify whether the problem is TOK, the Extended Essay, CAS or the combined core matrix before paying for subject exams. A subject retake cannot repair a separate core requirement by itself.

Costs, documents and the university handoff

IBretake pricing is EUR 150 registration plus EUR 600 for the first exam, EUR 570 for the second and EUR 540 for each exam from the third onward. Checkout currencies are converted from the EUR pricing. Budget separately for travel, accommodation, document delivery and bank charges.

Once a school accepts, follow its document and payment instructions promptly. After the retake result, arrange the official transcript route required by the university; a screenshot from the candidate website is not always accepted as final evidence.

Retake questions

Can you retake IB exams after graduating?
Yes. Former candidates can retake subjects in a future session if an IB World School offering the programme agrees to register them.
Do you have to retake all six IB subjects?
No. Many candidates retake only the subject or subjects needed for a Diploma condition, university offer or prerequisite.
Does the highest IB retake grade count?
The IB states that the highest grade achieved for a retaken subject contributes to the Diploma.
Can you retake the IB at a different school?
Potentially. The new school must offer the programme, accept external candidates and confirm the subject, level, session and logistics.
Can you retake an IB exam in November after a May session?
Potentially, if the subject is available and a participating school accepts you. Check when the January result would reach your university.
Can an IB retake lower the grade already on the Diploma?
The IB uses the highest grade achieved for the subject, but you should still confirm how a university treats multiple results or pending attempts.
Can I redo my IA during an IB retake?
Do not assume so. Discuss new, revised or carried-forward non-examination components with the coordinator before registration.
