similar schools
St Joseph's Catholic High School is a converter academy in Slough for boys and girls aged 11 to 18. It has 988 pupils, 188 more than it has places for. About 13 in every 100 pupils come from a low-income family, far fewer than at most schools in England. We give it 70 out of 100. That puts it above schools like it, ahead of 48% of the 50 schools most like it. Ofsted visited in May 2026 and gave it a report card, which is below.

A level subjects
16 A level subjects had results in 2025. Each figure is the share of students who got an A* to B, next to the average for state sixth forms in England. When only a handful of students take a subject, its figures jump around from year to year.
Every A level subject against England, 2025
A levels only. BTECs, T levels and other courses are in the table above. Subjects with fewer than five students aren't published.
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 3 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 has had free school meals at some point in the last six years. A group's figure isn't published when it has fewer than six pupils.
Getting a place
Open to all. There is no entrance test. As a Roman Catholic school it may put families of that faith first. Check the school's own admissions rules.
Fewer than one place in twenty is empty, so in most years more families apply than there are places. Living close by, or already having a child here, makes a real difference. Pupil numbers have stayed about the same since 2021/22.
Each council publishes its own figures on how many families applied and how far away the last child to get a place lived. We are adding councils one at a time. If you have a link to Slough council's admissions booklet, send it to us.
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.
The most common needs among pupils getting extra support: emotional and mental health (42), language and communications needs (30), Moderate learning difficulty (23), Specific learning difficulty (18), Autistic spectrum disorder (17), Physical disability (8).

Staff and money
From the government's count of school staff in November 2025 and the school's published accounts.
Money
From the academy accounts return, year to August 2025. The per-pupil figures are compared with other secondary schools in England that report their accounts the same way.
Reserves are the money left over at the end of the year, kept back for emergencies and big projects. Being in the red year after year is a warning sign. Very large reserves can mean money sitting in the bank instead of being spent on today's pupils. Academy figures are rounded to the nearest £1,000 and include a share of any money the trust holds centrally.
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 St Joseph's Catholic High School with the 48 schools in England 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 48 schools are dotted all over the country, so we don't list them. What matters is where this school sits among them.
How the score was worked out
The score is out of 100. A 70 means that once everything below is added up, this school comes out ahead of 70% of secondary schools in England. Results bounce around from year to year, especially in small schools, so we also show a likely range: 61 to 78. 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.
