Students are celebrating their GCSE results today (August 20) after weeks of anticipation and hard work.
Behind those grades are the all-important exam board grade boundaries, which determine what mark is needed for each grade.
Each subject and exam board has its own set of grade boundaries, determining the minimum number of marks required to achieve each grade.
These boundaries vary between boards and now, the 2026 grade boundaries have been published for AQA, OCR, Pearson Edexcel and WJEC.

Each exam board's grade boundaries help students and schools understand how raw exam marks translate into final grades.
Students and parents are advised to review the official grade boundaries to better understand the results and what they mean in terms of performance and progression.
How do grade boundaries differ in England and Wales?
In England, GCSEs are graded using a numerical system from 9 to 1, with 9 being the highest grade.
This was changed in 2017 and by 2020, all subjects were graded numerically, shifting away from the old A* to G system.
- I retook a GCSE maths test 11 years later - was my A* grade just a fluke?
- Results Day 2026 - free pizza, food and treats to celebrate or commiserate GCSEs
- Do teachers know GCSE results before students receive them?
A Grade 7 and above in England is roughly equivalent to an A and above.
A Grade 4 and above – which is considered a “standard pass” – is roughly equivalent to a C and above.
Meanwhile, in Wales, the traditional eight-category grade scale A*- G has been retained.
