St Mary's CofE (Aided) Primary School
Chessington, KT9 2DH · Kingston upon Thames · primary school
28th of 28 primary schools in Kingston upon Thames we can score, 35 in total — the rest without enough published data. Local and same-phase on purpose: a national table mostly measures who attends.
Narrow the comparison to the 3,134 schools whose pupils have similar backgrounds — a tougher field — and it places 0.8/10 among them, against 1.3/10 nationally. 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 |
|---|---|---|---|
| Expected standard (RWM) 2024/25 | 47.0 · 15 | 40% | 0.60 |
| Ofsted | 52 | 35% | 1.81 |
| Higher standard (RWM) 2024/25 | 0.0 · 10 | 25% | 0.26 |
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. In 2024/25, 47.0% of pupils reached the expected standard in reading, writing, and maths, compared to the national median of 64%. Only 0.0% reached the higher standard. Ofsted rated the school Good in November 2022. Narrow the comparison to the schools whose pupils have similar backgrounds — a tougher field — and it places 0.8 out of 10 among them, against 1.3 out of 10 nationally.
Beyond the classroom. Pupils can join Goodlife Gymnastics, Rocksteady Music School, BeSports, Arts and Crafts, Gardening, Construction, Homework, and Cookery clubs. Both a breakfast club and an after-school club are available.
Getting in. The school has 170 pupils in a capacity of 210, leaving 40 spare places. This means the school has real spare room, so a place is likely and classes are smaller than it is built for.
Worth asking on a visit. How does the school support pupils who are not reaching the expected standard in core subjects? What specific strategies are used to raise attainment from the current 47.0%? How does the school maintain its Good rating following the 2022 inspection?
