Herschel Grammar School
similar schools
Herschel Grammar School is a converter academy in Slough for boys and girls aged 11 to 18. It has 1,062 pupils, 162 more than it has places for. About 7 in every 100 pupils come from a low-income family, far fewer than at most schools in England. We give it 98 out of 100. That puts it well above schools like it, ahead of 78% of the 50 schools most like it. Ofsted's last grade was outstanding, back in 2024.

A level subjects
14 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.

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. 2 of the 3 gaps are 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
Grammar school. This is a grammar school, so places depend on an entrance test.
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: Autistic spectrum disorder (5), emotional and mental health (2), Specific learning difficulty (2), Vision impairment (2), language and communications needs (1).

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 Herschel Grammar School with the 50 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 50 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 98 means that once everything below is added up, this school comes out ahead of 98% of secondary schools in England. Results bounce around from year to year, especially in small schools, so we also show a likely range: 96 to 99. 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.
