GCSE grade boundaries 2026: how grades are set, and when they land
GCSE results day is Thursday 20 August 2026, and the exam boards publish the summer's grade boundaries at 8am that same morning — not before. Anyone promising the 2026 boundaries earlier is guessing. Here is how the boundaries and the 9–1 grades actually work, what counts as a pass, and what the numbers mean for what you do next.

When the boundaries publish, and where
Grade boundaries — the minimum raw mark for each grade, per subject, per exam board — are set only after all the summer's papers have been marked, and each board publishes its tables at 8am on results morning. For summer 2026 that is 20 August for GCSEs (A-level boundaries were published on 13 August). The official pages, which will carry the 2026 tables from 8am:
One detail worth knowing before you compare marks: modern GCSEs are linear, so the boundary applies to your total raw mark across all papers. The per-paper boundaries boards also publish are explicitly notional — illustrative only — and do not decide grades.
The 9–1 scale, translated
The number grades are statistically anchored to the old letters at three fixed points: the bottom of grade 7 aligns with the bottom of the old grade A, the bottom of grade 4 with the old grade C, and the bottom of grade 1 with the old grade G. So 9, 8 and 7 correspond to the old A* and A; 6, 5 and 4 to B and C; 3, 2 and 1 to D through G. Grade 9 is deliberately rarer than the old A* ever was: it is awarded by a formula — roughly the top fifth of everyone achieving grade 7 or above — rather than by a fixed mark percentage.
Two grades carry official names that matter for what happens next: grade 4 is the standard pass (the old grade C equivalent) and grade 5 is the strong pass. Most sixth forms, colleges and employers who ask for "a pass" mean a 4; course entry requirements often ask for 5s or better in specific subjects — the listing for your course is the only authority.
Why boundaries move every year — and why that protects you
Boundaries are not fixed percentages. Each summer, senior examiners and statisticians set them using predictions based on the cohort's prior attainment, so that a harder paper needs fewer marks for the same grade and an easier one needs more. That is why the same subject can need different marks at AQA and Edexcel in the same year, and different marks at the same board across two years — and why comparing your raw mark against last year's boundary tells you very little the night before results. The system is built so the grade means the same thing every year, even when the paper doesn't.
If a result lands close under a boundary, schools can request a review of marking through the board. Reviews can move marks in either direction, so the usual advice is to ask your school to check the mark first — they see the breakdown — and to weigh what a one-mark change would actually unlock before paying for a review.
What next, with the tools to hand
If English or maths landed below a 4, resits are the standard route — they are a condition of post-16 funding in England, and November sittings exist for exactly this. For everything else, the practical question is usually forward-looking: what do the next two years need to produce? If you are heading toward A-levels or BTECs with university in mind, our UCAS points calculator turns any combination of future grades into tariff points using UCAS's official 2026 tables — including the BTEC and T Level rows most calculators get wrong. And for coursework-and-exam subjects still in progress, the exam grade calculator answers the question every mock season asks: given the marks so far, what does the final paper need? Both run entirely in your browser — no accounts, and your marks never leave your device.
This page will be updated on results morning once the 2026 boundary tables are live on the board sites above.
