similar schools
Dr Challoner's High School is a converter academy in Amersham for girls aged 11 to 18. It has 1,391 pupils, 246 more than it has places for. About 3 in every 100 pupils come from a low-income family, far fewer than at most schools in England. We give it 99 out of 100. That puts it well above schools like it, ahead of 92% of the 50 schools most like it. Ofsted's last grade was outstanding, back in 2023.

Getting a place
Grammar school. This is a grammar school, so places depend on an entrance test.
The school is full, with 60 more pupils than it has places for. More families apply than can get in, so things like how close you live and whether an older brother or sister is already here decide who gets a place. Pupil numbers have grown by 5% since 2021/22, so places are getting harder to come by.
The last child to get a place lived 3.4 miles away in 2026, 4.8 miles away in 2025, 7.1 miles away in 2024. Those cut-offs are for children living outside the catchment area; every child inside it got a place. Brothers and sisters of current pupils and other priority groups are placed first. Type in your postcode to see how far away you are.
We measure in a straight line from the middle of your postcode to the school. The council measures its own way, and the cut-off changes every year. Use this as a rough guide, and read the council's admissions booklet before you apply.
How places were given out for September 2026. Every child in the catchment area who applied got a place. Outside the catchment, the last place went to a child living 3.4 miles away.
| Entry | How far the last child lived | Source |
|---|---|---|
| 2026 Secondary | 3.4 miles (distance, outside the catchment area) | LA |
| 2025 Secondary | 4.8 miles | LA |
| 2024 Secondary | 7.1 miles (sibling) | LA |
| 2023 Secondary | 5.6 miles (catchment area) | LA |
| 2022 Secondary | – (sibling) | LA |
| 2020 Secondary | 6.5 miles (catchment area) | LA |
The distances are the council's own, usually measured in a straight line from home to the school gate. If the distance is getting shorter each year, the school is getting harder to get into. See which councils we have this data for.
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 (16), Specific learning difficulty (9), Autistic spectrum disorder (6), Vision impairment (2), Multi-sensory impairment (1), Physical disability (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 Dr Challoner's High 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.
No school with a similar mix of pupils within 25 km scores clearly higher.
How the score was worked out
The score is out of 100. A 99 means that once everything below is added up, this school comes out ahead of 99% of secondary schools in England. Results bounce around from year to year, especially in small schools, so we also show a likely range: 97 to 100. 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.
