About Overton Grange School

Overton Grange School’s headline Progress 8 score of -0.17 sits well below the Sutton local authority average of 0.53, placing it 14th out of 16 state secondaries in the borough. That gap is significant — the LA average is among the strongest in the country, driven by selective grammar schools like Wilson’s School (Progress 8 of 1.27) and Sutton Grammar School for Boys (1.16). Overton Grange’s score means pupils here, on average, achieve nearly two-tenths of a grade less per subject than the national baseline, while the typical Sutton school adds half a grade per subject. The school’s Attainment 8 score of 47.1 — equivalent to just under a grade 5 per subject — is modest for the area. Just 40.5% of pupils achieved a grade 5 or above in English and maths, and only 7.9% entered the EBacc. The school’s Progress 8 banding is officially rated ‘Average’, but in the context of a high-performing LA, it’s an outlier.

In its most recent Ofsted inspection in December 2024, the school was judged as ‘Requires Improvement’ overall, a downgrade from its previous ‘Good’ rating in 2016. The inspection found quality of education and sixth-form provision both require improvement, while behaviour and attitudes, personal development, and leadership and management were all rated ‘Good’. At A-level, the school’s value-added score of -0.21 is ‘Below average’, with students averaging a C- grade across their best three A-levels. The sixth form is relatively small, with 82 students in the cohort. Parent View responses from 192 families paint a mixed picture: 81% would recommend the school, and strong majorities agree their child is happy (88% agree or strongly agree) and feels safe (89%). However, only 60% of parents who responded agree that SEND children receive the support they need, and 19% would not recommend the school.

The school is oversubscribed for Year 7 entry in 2025/26, with 538 applications for 211 places and 67 first-preference offers — an oversubscription ratio of 2.55. Facilities are strong for a state school: a swimming pool, theatre, astro turf, sports hall, music rooms, science labs, and a sixth-form centre. SEND provision covers a wide range of needs, including a resourced provision for specific learning difficulties and autistic spectrum disorder. The school offers a solid range of clubs — Duke of Edinburgh, Model UN, chess, drama, choir, and science club — and sports including hockey, netball, rugby, and martial arts. Overton Grange will suit families who value a broad, inclusive comprehensive with good behaviour and personal development, but who are realistic about academic outcomes that trail the Sutton average. The nearest Outstanding-rated school, Harris Academy Sutton, is just 0.6 km away, so it’s worth comparing both.
