GCSE Grade Boundaries 2026
Everything you need to know about GCSE grade boundaries for 2026 exams. Understand how boundaries are set, what marks you need for each grade, and how to use AI marking to predict your results.
What Are GCSE Grade Boundaries?
Grade boundaries are the minimum marks needed to achieve each grade in a GCSE exam. They are set after all papers have been marked, not before. This means boundaries change every year depending on how difficult the paper was and how well students performed nationally.
For example, if a paper was harder than usual, the grade boundaries will be lower to ensure the same proportion of students achieve each grade. This process, known as comparable outcomes, helps maintain fairness across different exam years.
Each exam board (AQA, Edexcel, OCR, WJEC) sets its own boundaries for each subject and paper. Boundaries are published on results day, typically in late August.
Typical GCSE Grade Boundaries
These are approximate percentage ranges based on recent years. Actual boundaries vary by subject, exam board, and year. Use these as a general guide for revision planning.
| Grade | Typical % | Description |
|---|---|---|
| 9 | ~80-90% | Exceptional performance. Top ~5% of candidates nationally. |
| 8 | ~70-80% | Outstanding achievement. Between the old A and A*. |
| 7 | ~60-70% | Excellent work. Equivalent to the old A grade. |
| 6 | ~50-60% | Very good. Upper end of the old B grade. |
| 5 | ~40-50% | Strong pass. The government's expected standard. |
| 4 | ~30-40% | Standard pass. Required for most college courses. |
| 3 | ~20-30% | Below pass. Equivalent to old D/E boundary. |
| 2 | ~10-20% | Limited achievement. Foundation tier upper range. |
| 1 | ~1-10% | Minimal achievement. Lowest numbered grade. |
Note: These percentages are indicative only. Actual grade boundaries are set by each exam board after marking is complete and may differ significantly from these ranges.
