There are no progress figures for 2025. That year group missed their Year 2 tests during Covid, so there was no starting point to measure from. Progress figures come back with the December 2026 results. Tests were cancelled altogether in 2020 and 2021.
Getting a place
Admissions policy not published. As a Church of England school it may put families of that faith first. Check the school's own admissions rules.
68 places were empty (28% of the total), so almost everyone who applies gets in. Pupil numbers have fallen by 4% since 2021/22, so places are getting easier to find.
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 Kingston upon Thames 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.

Staff and money
From the government's count of school staff in November 2025 and the school's published accounts.
Money
From the council school accounts, year to March 2025. The per-pupil figures are compared with other primary 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 Mary's CofE (Aided) Primary School with the 44 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 44 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 44 schools, these are within 25 km and score at least five points more than St Mary's CofE (Aided) Primary 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 24 means that once everything below is added up, this school comes out ahead of 24% of primary schools in England. Results bounce around from year to year, especially in small schools, so we also show a likely range: 11 to 50. That range is wide enough that the school could sit in the next band, so take the band as a rough guide rather than a verdict. 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.
