similar schools
Trinity St Mary's CofE Primary School is a Church of England school (voluntary aided) in London for boys and girls aged 2 to 11. It has 103 pupils and room for 210. About 57 in every 100 pupils come from a low-income family, far more than at most schools in England. We give it 83 out of 100. That puts it above schools like it, ahead of 98% of the 50 schools most like it. Ofsted's last grade was good, back in 2024.

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.
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 4 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 the end of primary school, 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
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.
104 places were empty (50% of the total), so almost everyone who applies gets in. Pupil numbers have fallen by 7% since 2021/22, so places are getting easier to find.
In 2026 every child who applied got a place, so how far away you live didn't matter. That could change if the school gets more popular.
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.

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.
Infant classes (Reception to Year 2) average 29.0 pupils (England 25.5); junior classes (Years 3 to 6) average 18.3 (England 27.3).
The most common needs among pupils getting extra support: emotional and mental health (7), language and communications needs (7), SEN support but no specialist assessment of type of need (6), Autistic spectrum disorder (1), Moderate learning difficulty (1), Vision impairment (1).

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 Trinity St Mary's CofE Primary School with the 46 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 46 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 83 means that once everything below is added up, this school comes out ahead of 83% of primary schools in England. Results bounce around from year to year, especially in small schools, so we also show a likely range: 59 to 93. 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.
