Sidlesham Primary School is a council school in Chichester for boys and girls aged 4 to 11. It has 139 pupils and room for 140. About 22 in every 100 pupils come from a low-income family, a bit fewer than at most schools. We give it 5 out of 100.

Results
Year 6 results (SATs), summer 2025
15 children took the tests. Here is how they did against every state primary in England. With a year group this small, a couple of children can move the percentages a long way.

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.
Fewer than one place in twenty is empty, so in most years more families apply than there are places. Living close by, or already having a child here, makes a real difference. Pupil numbers have stayed about the same since 2021/22.
The last child to get a place lived 2.7 miles away in 2025, 2.7 miles away in 2024. Children in care, brothers and sisters of current pupils, faith and other priority groups are placed first. After that, the closer you live, the better your chances. 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 2025. More children applied than there were places. The last place went to a child living 2.7 miles from the school. Living closer than that didn't guarantee a place, but living much further away meant missing out that year.
| Entry | Places | Applied at all | Got a place | How far the last child lived | Source |

| 2023 Primary | 20 | 18 | 18 | – all offered | 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: SEN support but no specialist assessment of type of need (12), language and communications needs (5), Autistic spectrum disorder (4), Other difficulty or disability (3), emotional and mental health (2), Moderate learning difficulty (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 Sidlesham Primary School with the 47 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 47 schools are dotted all over the country, so we don't list them. What matters is where this school sits among them.
How the score was worked out
The score is out of 100. A 5 means that once everything below is added up, this school comes out ahead of 5% of primary schools in England. Results bounce around from year to year, especially in small schools, so we also show a likely range: 2 to 13. 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.
