When a student asks about changing IB subjects mid-year, the request should be considered promptly but not approved automatically. The coordinator must determine whether the revised programme remains valid, whether required teaching and assessment can be completed, and whether the school can support the transition without creating unreasonable academic risk.
There is no single public IB subject change policy that guarantees or prohibits every change. The IB establishes programme, assessment, delivery, and registration requirements, while schools normally set their own approval procedures and internal deadlines. A defensible decision combines current IB rules with documented professional judgment.
Establish why the student wants to change
Meet the student before treating the request as a timetable problem. Common reasons include sustained difficulty, a mismatch with the assessment style, changed university plans, wellbeing concerns, movement between HL and SL, or an earlier misunderstanding of the course.
Use evidence rather than one disappointing test. Review assessment results, attendance, teacher feedback, study habits, language proficiency, and relevant pastoral information. Targeted support may be more appropriate when the problem concerns one topic, ineffective study methods, or a temporary difficulty.
Separate IB requirements from school policy
Families sometimes assume that the IB approves routine subject changes. In practice, the school decides what it can teach and timetable, but the coordinator must ensure that the resulting course of study and registration comply with IB requirements.
According to the IB Diploma Programme curriculum, Diploma students complete six subjects and the core. They take at least three and no more than four HL subjects, with the remaining subjects at SL. The subject-group pattern must also remain valid, including any permitted arts substitution or interdisciplinary arrangement.
The 2026 DP general regulations state that all HL subjects, the core, and at least one SL subject must be taught across the programme's two years. This makes a late move into an HL course particularly difficult. Joining a class does not prove that the full course has been properly taught.
School policy should identify required evidence, consultation responsibilities, approval authority, internal deadlines, timetable restrictions, possible fees, catch-up expectations, and review procedures.
Apply a structured feasibility check
The receiving teacher should complete a topic-by-topic and assessment-by-assessment audit. A general statement that the student is capable is not sufficient.
| Area | Question to resolve |
|---|---|
| Diploma structure | Will the combination preserve subject-group and HL/SL requirements? |
| Timetable | Can the student attend every required lesson without clashes? |
| Teaching | Which topics, texts, practicals, skills, or teaching hours were missed? |
| Assessment | Can every component be completed authentically by the applicable deadline? |
| University access | Does the change remove a required subject or level? |
| Staffing | Can the department provide the necessary teaching and supervision? |
| Wellbeing | Is catch-up realistic alongside TOK, CAS, the EE, and other subjects? |
| Administration | Is an IBIS amendment, deadline, or fee involved? |
An early DP1 transfer between courses with overlapping foundations may be manageable. A late change into a language, laboratory science, performance course, or portfolio-based subject may involve learning that cannot responsibly be compressed.
Students can preview course expectations through the RevisionDojo IB syllabus hub. The guide to choosing IB subjects can help families compare content and assessment formats instead of relying on a subject's reputation.
Audit assessment and coursework
Work completed for the former subject will not usually provide assessment evidence for the new one. The receiving teacher must identify all IA, oral, practical, portfolio, performance, and externally assessed coursework requirements.
The IB uses internal and external assessment, as outlined in its DP assessment overview. The school must preserve authenticity, required supervision, and permitted teacher support. A compressed schedule cannot justify excessive feedback, invented practical evidence, or work produced outside the required course context.
Also review the Extended Essay subject and supervision arrangements, inclusive access needs, internal deadlines, and the evidence available for predicted grades. RevisionDojo's IA feedback and moderation guidance may support criterion-based planning, but teachers must follow the current subject guide and feedback rules.
Check registration before confirming approval
Students and families cannot amend an IB assessment registration themselves. Registration and amendments are handled by the school through IBIS, with the school responsible for accurate entries.
Check the current session's Diploma Programme Assessment procedures, coordinator calendar, and IBIS record. Do not rely on a deadline remembered from an earlier cohort. The IB's assessment fees page explains that changing a subject, level, or language after applicable deadlines may incur additional fees.
Before confirming approval, verify:
- the subject, level, language, and examination session
- whether an IBIS amendment is required
- the applicable deadline and fee
- whether the assessment route remains available
- any effect on anticipated subjects or other registrations
Use a written transition plan
If the change is feasible, record the rationale, consultations, decision, registration action, financial implications, and effective date. The catch-up plan should identify missed content, weekly expectations, diagnostic tasks, assessment dates, support responsibilities, and a formal review after 2-4 weeks.
The RevisionDojo guide to changing subjects after Year 1 shows how students can map missed syllabus content. Study Notes, Flashcards, the Questionbank, and Jojo AI can support independent catch-up, but they cannot replace required teaching, practical participation, supervision, or authentic assessment.
When refusal is appropriate
A refusal may be necessary when the combination would be invalid, required teaching cannot be delivered, assessment cannot be completed authentically, or timetable participation is impossible. Explain the decision using published criteria and documented evidence.
Possible alternatives include targeted support, an HL-to-SL change, revised university planning, or DP Course Results where appropriate. The RevisionDojo mid-year subject-change guide can help families understand these options.
Conclusion
Changing IB subjects mid-year is sometimes possible, but approval requires a consistent review of Diploma structure, teaching, assessment, university implications, registration, timetabling, and wellbeing. Coordinators should document decisions and make approval conditional on a measurable catch-up plan. Once feasibility is confirmed, RevisionDojo's Study Notes, Questionbank, Flashcards, and Jojo AI can support the transition.
