GCSE grade boundaries explained
Ranging from 1-9, GCSE grade boundaries are tied to a set minimum GCSE score and set by national exam boards, across all subjects. These are Edexcel, AQA, OCR, and WJEC.
Each exam board has their own minimum GCSE test score for each grade boundary. This is because they each use different approaches for assessment.
Paying attention to GCSE grade boundaries is important for your child’s academic and professional potential. Aiming for the highest possible number will ensure maximum opportunities in the future.

What are the GCSE grade boundaries and what GCSE grade boundary is a pass?
A GCSE grade 4 is considered a pass. However many sixth forms won’t accept students with lower than a 6.
It's also worth noting that a 3 or below will result in a required resit for both Maths and English.
How are GCSE grade boundaries decided?
To determine grade boundaries, each exam board evaluates performance year over year and aligns minimum scores with testing difficulty. This means they assess the content of each subject and make sure it’s not harder to achieve a certain grade boundary than in previous exams.
The grade boundary system was set to ensure that universities can better assess a student’s performance.
Why do GCSE grade boundaries change each year?
As you might imagine, having grade boundaries set each year poses a challenge when trying to determine minimum GCSE subject test scores. To provide as much transparency as possible, grade boundaries are released on GCSE test results day. In addition, the previous year’s boundaries are accessible online for each exam board.
Also, while it may seem logical to use the same boundaries each year, there are other factors which influence grade boundaries. For example, GCSE grade boundaries in 2021 and 2022 reflected the impact of the COVID-19 pandemic. The goal is to ensure maximum fairness each year.
