On 2025 Attainment 8, Avanti House School topped the table in Harrow with 64.0, against an England average of 46.1. 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.

Where are the latest Harrow GCSE results?

This page is the 2025 archive (the 2024/25 academic year). The latest published results for every school in Harrow are on the main Harrow GCSE results page, which updates when the DfE releases the next year's performance tables: provisional figures in the autumn, revised figures early in the new year.

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 Harrow show no 2025 GCSE results?

A school has no published figure for 2025 when it had no Year 11 cohort in that year (a new school, or one that opened with younger year groups), when it converted to an academy and the DfE published that year's 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 Harrow with published 2025 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 46.1.

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. 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.

This is the 2025 archive of the table: each school's 2025 figures, ranked within that year, so a school with no 2025 figure is listed unranked even where it has results for a later year. The main Harrow GCSE results page always ranks the newest year the DfE has published.
