At GCSE, the school's average Attainment 8 score was 47.8, broadly in line with the national average of 46. On our composite score, School 21 ranks in the top 42% of primary schools nationally for its primary (KS2) results.

Pupils achieved an average scaled score of 106 in reading and 104 in maths (national averages are about 105 and 104). 9% reached the higher standard across all three subjects (around 8% do so nationally). At Key Stage 4, 48% of pupils achieved a grade 5 or above in both English and maths, in line with the national average of about 45%. School 21 was not oversubscribed for September 2026: all 27 families who put it first were offered a place. Overall pupil absence was 7.4%. There are about 13.7 pupils per teacher. The school serves a community with above-average levels of disadvantage: about 48% of pupils have been eligible for free school meals in the last six years, compared with roughly 24% nationally — useful context when reading the results above. School 21 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.
