GCSE grade boundaries, explained simply

The 9-1 scale in one minute

GCSEs are graded 9 down to 1, with 9 the highest. Grade 4 is a 'standard pass' and grade 5 a 'strong pass'; sixth forms and employers commonly ask for specific grades (a 5 or 6 in maths and English is a typical gate). There is no fixed national mark for any grade.

Why boundaries change every year

Boundaries are set after each exam series, once papers are marked, so that the standard of work required for each grade stays comparable between years even if the paper was harder or easier. That means the mark for a grade 7 in June is not the mark for November, and it differs between AQA, Edexcel and OCR. No one can tell you the boundary before results day; anyone who claims a fixed 'pass mark' is guessing.

How to use boundaries in revision

Take last summer's boundaries for your board and subject as a realistic target: count up the marks your child needs across all papers, then work backwards to the topics where those marks are most recoverable. A student needing 15 more marks should not start with their hardest topic; they should start where questions are worth 3-4 marks and the fix is mechanical.

What this means for parents

Judge mock results against the full-paper mark total, not a percentage. A '60%' score means different grades on different papers and tiers. Tutors who mark against real boundaries (as ours do weekly) can tell you whether the trajectory reaches the target grade before the entry deadline arrives.
