Check the area around this school
17th of 45 primary schools in Hounslow we can score, 50 in total — the rest without enough published data. 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 — 7.6/10 against 4,242 of them, against 7.6/10 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 |
|---|---|---|---|
| Expected standard (RWM) 2024/25 | 76.0 · 80 | 40% | 3.20 |
| Ofsted | 52 | 35% | 1.82 |
| Higher standard (RWM) 2024/25 | 11.0 · 71 | 25% | 1.77 |
Each measure is read as a position among comparable schools, so a school in the middle of the country scores 5. Full method.

What Ofsted said about St Mary's Catholic Primary School, Isleworth
Overview
St Mary’s Catholic Primary School continues to be a good school, where pupils feel happy, safe, and grateful to be part of the ‘St Mary’s family’. Leaders have established a well-thought-out, ambitious curriculum that prepares pupils effectively for the next stage of their education.
Strengths
- Pupils display polite, kind, and respectful behaviour, with bullying being unusual and swiftly addressed by staff.
- Teachers introduce learning in clear, manageable chunks, ensuring pupils, including those with special educational needs and/or disabilities (SEND), learn the curriculum well.
- Leaders prioritise early reading, with a phonics programme followed consistently across the school, fostering a genuine love of reading among pupils.
- Staff workload is manageable due to streamlined marking expectations, and staff feel supported by approachable leaders.
- Pupils benefit from varied experiences outside lessons, including a daily mile run and high-uptake after-school clubs, promoting wider social development.
Areas to improve
- In a few subjects, pupils’ misconceptions are not always identified and addressed timely, meaning understanding is not always secure.
- Occasionally, younger pupils are given books that are too difficult, which hinders the development of their reading fluency and confidence.
Safeguarding
The arrangements for safeguarding are effective, with rigorous recruitment checks and staff who are clear about their responsibilities and warning signs of risk.
