Glenthorne High School
Sutton, SM3 9PS · Sutton · secondary school
6th of 15 secondary schools in Sutton we can score. Local and same-phase on purpose: a national table mostly measures who attends.
Its results hold up when the comparison narrows to schools whose pupils have similar backgrounds — 9.2/10 against 709 of them, against 9.3/10 nationally. So this is not simply a reflection of who attends. Both figures are results only, without the inspection grade. A lower figure here means a stronger comparison group, not a weaker school.
How this is worked out
| Measure | Percentile | Weight | Adds |
|---|---|---|---|
| Ofsted | 87 | 35% | 3.04 |
| Grade 5+ English & maths 2024/25 | 75.2 · 93 | 30% | 2.79 |
| Progress 8 2023/24 | 0.75 · 93 | 25% | 2.32 |
| Attainment 8 2024/25 | 61.6 · 93 | 10% | 0.93 |
Each measure is read as a position among comparable schools, so a school in the middle of the country scores 5. Full method.
Get to know the school
How it's doing. The school is rated Good by Ofsted following a January 2026 inspection. In 2024/25, 75.2% of pupils achieved Grade 5 or above in English and maths. Attainment 8 was 61.6, compared to the national median of 44.6. Progress 8 was +0.75 in 2023/24, indicating pupils did better than those nationally who started from the same place. Its results hold up when the comparison narrows to schools whose pupils have similar backgrounds, so they are not simply a reflection of who attends (9.2 out of 10 against similar schools, 9.3 out of 10 against all schools).
Beyond the classroom. Pupils can join ArtsOne, ArtsOne Dance, ArtsOne Drama, ArtsOne Rocks!, the Dance Academy, Football Academy, and an athletics club. Trips include a house camping challenge, theatre visits, exhibitions, museums, and local colleges.
Getting in. There are 1782 pupils in a school with 1558 places, meaning it is over capacity by 224. The school is over its stated capacity, so places are competitive.
Worth asking on a visit. How does the school manage the high demand for places given it is over capacity? What support is available for pupils who need to catch up on progress? How are the various ArtsOne clubs structured for new students?
