The Magna Carta School

School overview

The Magna Carta School is a secondary school serving Staines-upon-Thames, Surrey, classified by the DfE as a converter academy. It has 1,029 pupils aged 11 to 16 on roll. In the most recent GCSE results, pupils achieved an average Attainment 8 score of 46.7, broadly in line with the national average of 46. That is down 2.1 points in its Attainment 8 score on the previous year. On our composite score, which combines the DfE attainment measures above, this places it in the top 44% of secondary schools nationally.

46% of pupils achieved a grade 5 or above in both English and maths, in line with the national average of about 45%. 66% achieved a standard pass (grade 4+) in English and maths. The Magna Carta School was not oversubscribed for September 2026: all 155 families who put it first were offered a place. After Year 11, 94% of its leavers went on to education, an apprenticeship or work that they stayed in for at least two terms. Overall pupil absence was 8.3%. There are about 15.7 pupils per teacher. The Magna Carta School does not currently have a recent graded Ofsted judgement on record (often the case for newer or recently converted schools), so it is worth asking when its next inspection is expected.
