Which school has the best GCSE results in Suffolk?

On 2025 Attainment 8, Debenham High School tops the table in Suffolk with 55.7, against an England average of 46.0. Attainment 8 rewards intake as well as teaching, so compare a school's grade 5+ pass rate and, where published, its Progress 8 before reading the rank as a verdict.

When are the 2026 GCSE results for Suffolk schools published?

Pupils receive their results in August, but school-by-school figures come from the DfE performance tables, which publish provisional results in the autumn (usually mid-October) and revised figures early in the new year. This table shows 2025 results, the 2024/25 academic year, and updates when the next release is imported.

What is Attainment 8?

Attainment 8 is the DfE's headline GCSE measure: the average points a school's pupils achieved across eight qualifications, with English and maths counted twice. A score of 50 means pupils averaged roughly a grade 5 across those subjects. No Progress 8 exists for 2025 because these pupils sat no Key Stage 2 tests in 2020.

Why does a school in Suffolk show no GCSE results?

A school has no published figure when it had no Year 11 cohort in the year (a new school, or one that opened with younger year groups), when it converted to an academy and the DfE published results under its previous identity, or when it is independent and its pupils sat IGCSE, Pre-U or IB qualifications that the DfE tables do not count. Independent schools with a published figure are listed separately and unranked for that reason.

Independent schools in Suffolk with published GCSE results

Listed as published, not ranked. The DfE tables count only reformed GCSEs, so a school whose pupils sit IGCSE, Pre-U or the IB reports a lower figure than its results merit, or none at all. Compare independent schools on their own published examination results and inspection reports.

How to read this table

Attainment 8 is the average points a school's pupils achieved across eight GCSE subjects: English and maths (double-weighted), three EBacc subjects (sciences, computing, history, geography, languages) and three further approved qualifications. The DfE publishes it for every state school; the England average for 2025 was 46.0.

Grade 5+ in English and maths is the share of pupils reaching a "strong pass" in both; grade 4+ is the "standard pass". EBacc APS is the average point score across the English Baccalaureate subjects, including pupils who did not enter them.

Progress 8 is not shown: the DfE published no Progress 8 for 2025 because these pupils sat no Key Stage 2 tests in 2020, the baseline it is measured from, and the same applies to 2026. Attainment 8 rewards intake as well as teaching, so a selective school will usually top an attainment-only table.

Ranks are shared where scores tie. Schools are ranked here on published results alone; our composite score, which also weighs Ofsted inspection, progress and attendance, orders the same schools on the best secondary schools page.
