May 2027 IB retake timeline: the M27 planning guide

August–September 2026: define the retake

Start with the official result, not a vague target. Record subject, level, grade, marks to the next boundary, curriculum or course code, candidate session number and the university condition you are trying to meet.

Decide whether a Category 1 EUR is realistic, but do not wait for it before checking M27 availability when timing matters. A remark and a host-school search can run in parallel until one route solves the problem.

• Choose the smallest subject set that changes the Diploma or admissions outcome.
• Ask the former school what results, IA or core work can be carried forward.
• Prepare identity document, result statement, candidate details and location options.

September–December 2026: secure a host school

A private candidate cannot register directly with the IB. An IB World School must accept the candidate and confirm the exact subject, level, language, session and curriculum. Availability differs even between nearby schools.

Do not treat an enquiry or payment receipt as official registration. Ask when the school will confirm acceptance, what documents it needs, its internal cutoff, where exams take place and how it handles timetable conflicts or access arrangements.

January–February 2027: close the registration risks

By this stage, the goal is not more browsing; it is a complete school file. Confirm the registered name, date of birth, candidate details, every subject and level, fee status and the coordinator contact who will issue exam instructions.

Schools set internal deadlines before the IB workflow closes, and late changes may be restricted or cost more. There is no safe universal student deadline: use the date in writing from the accepting school.

• Match passport name and IB record exactly.
• Check subject codes and level line by line.
• Confirm carried-forward components and anything that must be completed.
• Tell the university the expected May-session result timing.

March–April 2027: timetable, travel and exam readiness

Use the final subject timetable supplied by the coordinator, not the provisional window alone. Book travel only after the exam centre and dates are confirmed, and arrive with enough buffer for identity checks and local disruptions.

Build revision around actual papers and time zones. Confirm permitted calculators, stationery, access arrangements, reporting time and the contact route for urgent exam-day issues.

Final 23 April–18 May 2027 examination calendar

The final-version schedule copy supplied for May 2027 lists examinations from Friday 23 April through Tuesday 18 May across zones A, B and C. It replaces the earlier provisional planning window. Use the complete paper-level calendar and confirm your personal timetable with the accepting school.

Do not infer a subject date from the broad window or book non-refundable travel from this article alone. The accepting coordinator remains responsible for your official entry, location, local reporting time, permitted equipment and any updated operational instruction.

After the exams: results and university handoff

Before results, tell the coordinator which universities or admissions centres should receive the official transcript. Give admissions the expected result window and ask whether a conditional offer, deferral or document deadline needs a separate update.

When results arrive, check the full Diploma conditions as well as the new subject grade. A higher subject result may still need an official transcript before the university can act.

Read the final calendar as a personal workload map

The final-version schedule copy supplied for May 2027 lists papers from Friday 23 April through Tuesday 18 May, across zones A, B and C. It supersedes the earlier provisional planning window. Build your plan from the paper-level calendar: record every paper, zone, local start time and same-week cluster for your exact subjects.

The timetable is only one layer. Your accepting school controls arrival instructions, room, identity checks, permitted equipment and local communication. Before buying non-refundable travel, obtain the coordinator's written confirmation of your registered subjects, examination location and reporting times. If a timetable changes, the coordinator-issued instructions are operationally decisive.

• Copy every paper separately; do not record only the subject's first day.
• Add the published zone start time, then confirm the school's local reporting time.
• Mark two-paper days and consecutive-day clusters before fixing the revision order.
• Keep travel and university evidence deadlines in the same calendar as the examinations.
