Registering for your IB examinations is one of the most important administrative steps in the Diploma Programme (DP) or Career-related Programme (CP). Missing a registration deadline can result in additional fees, limited options, or, in some cases, being unable to sit your exams during your intended examination session. Whether you're preparing for the May or November examination session, understanding how the registration process works will help ensure everything is completed on time. In this guide, we'll explain the IB exam registration timeline, who is responsible for registering candidates, and what you should do to avoid any last-minute issues.
IB Exam Registration Deadline
Who Registers Students for IB Exams?
Students do not register directly with the International Baccalaureate (IB). Instead, exam registration is handled by your IB World School through the school's IB Diploma Programme or Career-related Programme coordinator. Your coordinator is responsible for:
Registering you for all subjects and examination components.
Entering your Higher Level (HL) and Standard Level (SL) subjects correctly.
Registering any retake examinations.
Submitting requests for accessibility arrangements, where applicable.
Ensuring all registration information is accurate before IB deadlines.
Although the school completes the registration, it is ultimately your responsibility to check that your subject selections and personal details are correct.
May and November Examination Sessions
The IB offers two examination sessions each year:
May Session – This is the largest examination session and is taken by the majority of IB students worldwide. Most schools begin confirming subject registrations several months before the examinations, often during the first semester of the DP2 academic year.
November Session – The November session is available at selected IB World Schools, primarily in countries where the academic calendar differs from the traditional Northern Hemisphere schedule, or when students are unable to take their exams in the May session. Registration follows a similar process but with earlier deadlines relative to the examination dates.
When Are IB Registration Deadlines?
The IB has official registration deadlines for every examination session, but students rarely submit registrations directly to the IB. Instead, schools establish internal deadlines that are often several weeks before the official IB deadlines. These earlier deadlines give coordinators enough time to verify candidate information, resolve subject selection issues, submit registrations without late fees, and make any necessary amendments before the final deadline. For this reason, you should always follow the deadline provided by your IB coordinator rather than waiting until the official IB registration date. For the May examination session, schools must complete candidate registration by mid-October of the previous year. For the November examination session, the registration deadline is mid-April.
Inclusive Exam Arrangements
Students who require inclusive access arrangements, such as additional time for exams or other approved examination accommodations (e.g. larger font size for students with visual impairments), should notify their IB coordinator as early as possible. Schools must submit these requests well in advance of the examination session, with some specialized accommodations requiring up to one year of advance notice. Planning ahead ensures that the necessary arrangements can be approved and implemented before exam day.
What Information Will You Need?
Before your registration is submitted, you should carefully confirm that:
Your full legal name matches your identification documents
Your date of birth is correct.
Your selected IB subjects are accurate.
Your HL and SL levels are correct.
Any first-time or retake subjects are listed correctly.
Any required accessibility arrangements have been requested.
Any differences between your registered name/date of birth and the identification you present on exam day could cause delays or complications when verifying your identity and may affect the issuing of your IB results and diploma. Confirm that each subject is registered at the correct level, since HL and SL have different syllabi, assessments, and examination papers.
What Happens if You Miss the Deadline?
Missing your school's registration deadline does not automatically mean you cannot take your exams, but it may result in additional costs or administrative difficulties. Possible consequences include late registration fees, restrictions on changing subjects or examination levels, and delays in processing special accessibility arrangements. In rare cases, this may mean being unable to register for the intended examination session if final IB deadlines have passed. This could result in delayed university applications and higher education start dates. If you think you may miss your school's deadline, contact your IB coordinator as soon as possible. The earlier they are informed, the more likely they will be able to help.
Can You Change Your Subjects After Registering?
In some cases, yes. Subject changes are sometimes possible after registration, but they depend on IB regulations and your school's policies. For example, you may wish to change from SL to HL (or vice versa), change an optional subject, withdraw from a subject, or register for a retake examination. Some changes may involve additional fees or specific deadlines, so discuss any concerns with your IB coordinator well before the examinations.
Tips for Staying on Schedule
To avoid unnecessary stress, keep these tips in mind throughout the registration process:
- Pay close attention to emails and announcements from your IB coordinator – Your IB coordinator will provide important updates about registration deadlines, examination procedures, required documents, and any changes you need to be aware of.
- Record your school's internal registration deadline in your calendar – Setting reminders for your school's registration deadline helps ensure you complete all required steps on time and avoid unnecessary late fees or registration issues.
- Double-check all personal and subject information before confirming your registration – Carefully reviewing your registration details can help prevent administrative errors that may affect your exams or results.
- Raise any concerns about subject selections as early as possible – If you're unsure about your subject choices or need to make changes, speaking with your IB coordinator early gives you the best chance of resolving any issues before registration closes.
- Complete any required school forms or payments promptly – Submitting all required paperwork and examination fees by your school's deadlines helps ensure your registration is processed without delays.
