St Mark's Church of England Academy is a sponsored academy in Mitcham for boys and girls aged 11 to 18. It has 983 pupils, 83 more than it has places for. About 49 in every 100 pupils come from a low-income family, far more than at most schools in England. We give it 87 out of 100. That puts it well above schools like it, ahead of 98% of the 50 schools most like it. Ofsted's last grade was outstanding, back in 2024.

A level subjects

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
Open to all. There is no entrance test. As a Church of England school it may put families of that faith first. Check the school's own admissions rules.
About 109 places were empty, so most families who apply get in, though a popular year group can still fill up. Pupil numbers have grown by 17% since 2021/22, so places are getting harder to come by.
How places were given out for September 2026.
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 (95), language and communications needs (42), Specific learning difficulty (40), Autistic spectrum disorder (23), SEN support but no specialist assessment of type of need (16), Moderate learning difficulty (14).

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 Mark's Church of England Academy 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 87 means that once everything below is added up, this school comes out ahead of 87% of secondary schools in England. Results bounce around from year to year, especially in small schools, so we also show a likely range: 82 to 91. 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.
