St Mary's Church of England Primary School
Slough, SL1 2AR · Slough · primary school
20th of 27 primary schools in Slough we can score, 28 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 schools whose pupils have similar backgrounds and it does better still — 6.3/10 against 2,452 of them, against 5.3/10 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 | 71.0 · 68 | 40% | 2.73 |
| Ofsted | 52 | 35% | 1.81 |
| Higher standard (RWM) 2024/25 | 3.0 · 29 | 25% | 0.73 |
Each measure is read as a position among comparable schools, so a school in the middle of the country scores 5. Full method.

Getting in. The school has 675 pupils in a capacity of 682 places, leaving 7 spare spots. The school is close to full, so places are likely to be competitive.
Worth asking on a visit. With only 7 places remaining, what is the current waiting list length for a new intake? How does the school support pupils who do not reach the higher standard in their core subjects? What specific support is available for children who need extra help with reading or writing?
