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.

Does every child do well here?
A good school does well by every child, not just on average. Each row compares two groups of pupils here. The grey marks show the same two groups across England. 1 of the 4 gaps is smaller than the gap across England. When a group has fewer than about ten pupils, its figures jump around a lot from year to year.
At GCSE, 2025
Low-income means the child gets free school meals. The Welsh figures are averaged over three years, and the grey marks show Wales rather than England.
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 in English.
You apply through Merthyr Tydfil council, not the school.
Who goes here
Who a school teaches matters. That is why our score compares it with schools that take in a similar mix of children, not with every school in the country.
How the mix of pupils has changed

Attendance
In 2024/25 pupils were in school 89.0% of the time. Across secondary schools in Wales it was 89.6%. 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, £55 more than the Welsh average for secondary 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.

Compared with schools like it
Our score compares Cyfarthfa High School with the 50 schools in Wales whose pupils are most like its own. We match on family income, how many children are learning English, special needs, the neighbourhood, the size of the school and how it admits pupils. Those 50 schools are dotted all over the country, so we don't list them. What matters is where this school sits among them.
Nearby schools with a similar mix of pupils that score higher
Of those 50 schools, these are within 25 km and score at least five points more than Cyfarthfa High School, nearest first. A school with the same kind of pupils and a higher score is the fairest sign that it gets more out of them.

How the score was worked out
The score is out of 100. A 54 means that once everything below is added up, this school comes out ahead of 54% of secondary schools in Wales. Results bounce around from year to year, especially in small schools, so we also show a likely range: 44 to 63. Every part is judged against schools with a similar mix of pupils. For small schools we pull each part towards the group average, so one unusual year can't swing the score too far.
