Can my child switch between the IB, A-Levels, or AP mid-course when we relocate?

The short answer: switch at a clean break point, not mid-cycle. The terminal two-year programmes — the IB Diploma and A-Levels — are built to run start-to-finish, so joining or leaving one partway through is hard and often means repeating a year. The realistic windows are before the final two years begin (e.g. after IGCSE/Year 11) or at the very start of the first sixth-form year; a move well into Year 12, and especially into Year 13, is rarely workable. Why the two-year programmes resist a mid-course switch: the IB Diploma builds cumulatively — internal assessments, the Extended Essay, and CAS accumulate across both years — so joining after DP1 has started leaves gaps that can't be back-filled. A-Levels are modular by subject but assessed by terminal exams, so arriving mid-Year-12 usually means missing content or repeating the year. Partial-Diploma or partial-A-Level 'credit' does not transfer cleanly between the two systems. The clean windows, in order of ease: (1) the easiest is before the sixth-form years begin — a relocation just after an exam cycle like IGCSE/GCSE lets a child start the new system fresh; (2) the start of the first sixth-form year (beginning DP1, or Year 12 A-Levels) is workable if it's genuinely the beginning; (3) between the two sixth-form years is discouraged and often means repeating; (4) mid-Year-13, don't — if a relocation forces it, the usual advice is to finish the original programme (sometimes remotely) rather than switch. Two honest caveats. First, this is the general pattern across schools, not a fixed rule — every school sets its own admission-point and catch-up policy, so confirm viability directly with the specific school before you commit to a move. Second, universities are generally comfortable with a student who changed systems for a legitimate reason like relocation, provided the final qualification is complete and coherent — a documented move is not the red flag families fear; an unfinished or patchwork qualification is the real risk.
