England's highest achieved secondary schools based on this year's GCSE results have now been named - and a Kingston school is on the list.

On Thursday (16 October), the Department for Education (DfE) released its new preliminary 2024/25 key stage 4 performance data for state-funded secondary schools across England.

This year, the default metric schools are sorted by is their Attainment 8 score rather than its usual progress score.

Tiffin Girl's school in Kingston was ranked fourth on the list with an incredible Attainment 8 score of 85.1 for the 2024/25 academic year.

However, in first place was the Henrietta Barnett School in Barnet, and in second place was Wilson's School in nearby Sutton, which achieved an Attainment 8 Score of 86.7.

On the Government's compare schools website, it says it was not able to calculate Progress 8 scores for the most recent school year, nor will it be able to do so for the current 2025/26 one.

It added:  "This is because there is no [key stage two] assessment data available to calculate the baseline for Progress 8 for these years due to Covid-19 disruption."

While Progress 8 scores measure pupil progress from the end of primary school through to when they take their GCSEs, the Attainment 8 score shows how pupils have performed without taking their starting points into account.

It is calculated using their grades in the compulsory English and maths GCSEs double-weighted, as well as in three other English Baccalaureate subjects (which include sciences, languages, history and geography), and then in three additional GCSE subjects or other approved qualifications.

A school's Attainment 8 score is the average score of all pupils across the year group. These scores also roughly align with the new 9 – 1 GCSE grading scale, meaning that if you divide them by 10, you'll get an average grade - with 9 being the highest possible grade.
