Marish Primary School
similar schools
Marish Primary School is a converter academy in Slough for boys and girls aged 3 to 11. It has 763 pupils and room for 806. About 20 in every 100 pupils come from a low-income family, a bit fewer than at most schools. We give it 91 out of 100. That puts it well above schools like it, ahead of 80% of the 50 schools most like it. Ofsted's last grade was good, back in 2022.

What Ofsted found
Ofsted's last full inspection was on 10 May 2022, back when it gave schools one overall grade. Read the report on Ofsted's website.
Good overall.
This inspection is more than 4 years old. When Ofsted next visits, the school will get a report card instead of one grade.

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. 1 of the 4 gaps is 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.
The school is full, with 24 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 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.
Specialist SEND provision. SEN unit with 93 pupils, for autism, hearing impairment, moderate learning difficulties, physical disability, social, emotional and mental health, speech, language and communication, visual impairment.
To get a place in the unit or resourced provision, a child normally needs an education, health and care plan (EHCP) that names the school. Other schools in Slough with autism provision.
Infant classes (Reception to Year 2) average 21.1 pupils (England 25.5); junior classes (Years 3 to 6) average 28.4 (England 27.3).
The most common needs among pupils getting extra support: Autistic spectrum disorder (82), SEN support but no specialist assessment of type of need (73), language and communications needs (58), Other difficulty or disability (5), Specific learning difficulty (5), emotional and mental health (4).

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 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 Marish Primary School with the 49 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 49 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 49 schools, these are within 25 km and score at least five points more than Marish 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 91 means that once everything below is added up, this school comes out ahead of 91% of primary schools in England. Results bounce around from year to year, especially in small schools, so we also show a likely range: 85 to 95. 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.
