Inspection
Schools in Wales are inspected by Estyn, not Ofsted. Since September 2022 Estyn's reports describe what a school does well and what it needs to work on, without giving a grade.
Estyn's latest report, and any follow-up visits, are on Estyn's website. The only schools given a formal label are those in special measures or needing significant improvement.
Results
Wales stopped publishing results for individual primary schools in 2019, so there are none to show. Attendance, pupil numbers and staffing below come from the Welsh Government's My Local School.
Getting a place
There is no entrance test. The council hands out the places. Brothers and sisters of current pupils and other priority groups go first; after that, the closer you live, the better your chances.
Teaching is mainly in Welsh.
You apply through Caerphilly council, not the school.

Attendance
In 2024/25 pupils were in school 94.3% of the time. Across primary schools in Wales it was 92.8%. Wales doesn't publish figures on pupils who miss a lot of school, or on exclusions, for individual schools.
Staff and budget
From the Welsh Government's My Local School, 2025/26.
The budget is the money the council gave the school to spend per pupil in 2025/26, £1,205 less than the Welsh average for primary schools. Small and rural schools tend to get more per pupil.
The area around the school
Crime figures come from police.uk. The police record each crime at the nearest of a fixed set of map points rather than the exact spot, so “within 500 m” is only rough. House prices are from HM Land Registry sales nearby over the last two years.
