Warren Dell Primary School
similar schools
Warren Dell Primary School is a converter academy in Watford for boys and girls aged 2 to 11. It has 264 pupils and every place is taken. About 23 in every 100 pupils come from a low-income family, about the same as most schools in England. We give it 87 out of 100. That puts it well above schools like it, ahead of 84% of the 50 schools most like it. Ofsted's last grade was outstanding, 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.
† These results are for Warren Dell Primary School, the school this one replaced in September 2017. Same building and the same children. It got a new registration number, usually because it joined an academy trust.
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.
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 grown by 6% since 2021/22, so places are getting harder to come by.
The last child to get a place lived 700 m away in 2025, 880 m 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 2026. More children applied than there were places. The last place went to a child chosen by how close to the school they lived, but the council didn't publish how far away that was.

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.
What a home within 790 m of the school costs
Every home sold within that distance of the school (the typical cut-off over the last three years), of any type, from HM Land Registry records. If homes here cost more than the district average, that is the price people pay to live close enough to get in.
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. Resourced provision (extra staff and funding within a mainstream school) with 6 pupils, for autism, speech, language and communication.
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 Hertfordshire with autism provision.
Infant classes (Reception to Year 2) average 27.0 pupils (England 25.5); junior classes (Years 3 to 6) average 20.7 (England 27.3).
The most common needs among pupils getting extra support: language and communications needs (28), emotional and mental health (18), Autistic spectrum disorder (6), Moderate learning difficulty (4), SEN support but no specialist assessment of type of need (1).

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 Warren Dell 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 Warren Dell 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 87 means that once everything below is added up, this school comes out ahead of 87% of primary schools in England. Results bounce around from year to year, especially in small schools, so we also show a likely range: 72 to 94. 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.
