School catchment areas explained
How school catchment areas work in England: the oversubscription criteria, how distance is measured, and why catchment never guarantees a place.
A school catchment area is the part of an area a school gives priority to when it has more applicants than places. It sounds simple, but catchment is one of the most misunderstood parts of school admissions in England. It is not always a fixed line on a map, and even where a mapped area exists, living inside it does not guarantee a place. This guide explains what a catchment area really is, how schools decide who gets in, how distance is measured, and why the effective cut-off can move from year to year.
What a catchment area is, and what it is not
In everyday use, "catchment" means the area a school draws its pupils from. In admissions terms it is narrower than that. A catchment area is one possible way a school gives priority when it is oversubscribed, meaning more children apply than there are places. Some schools have a formal, mapped catchment or priority area. Many others have none at all and simply use distance from the school as a tie-breaker.
Two things follow from this. First, not every school has a catchment area in the formal sense, so it is worth checking rather than assuming. Second, even where a catchment exists, it sits inside a longer list of admission rules. Being in the catchment moves you up that list, but it does not jump you past the children the law puts first.
How schools decide who gets in
Every state school's admission authority, which is the council for community and voluntary-controlled schools, the governing body for foundation and voluntary-aided schools, and the academy trust for academies and free schools, publishes the school's admission arrangements, including the oversubscription criteria used when there are more applicants than places. As GOV.UK puts it, "All schools have admission criteria to decide which children get places." When a school is full, places are offered strictly in the order those criteria set out.
A statutory rule sits above everything else. Under the School Admissions Code, a child whose education, health and care (EHC) plan names the school must be admitted, ahead of the oversubscription criteria. After that, looked-after children and children who were previously looked after are the highest priority within the oversubscription criteria. After those groups, the admission authority chooses from a familiar set of criteria, which commonly include:
- Children with a brother or sister already at the school.
- Children who live closest to the school, measured by distance.
- Children inside a defined catchment or priority area.
- Children of a particular faith, at faith schools.
- Children who attended a named feeder school.
- Children who pass an entrance test, at grammar and other selective schools.
- Children eligible for the pupil premium or service pupil premium, where the school's arrangements include this.
Each admission authority sets its own order, so two schools on the same street can rank these factors differently. The published arrangements are the only reliable guide to how a specific school decides.
How distance is measured
Where distance is used, the detail matters more than parents expect. A common method is to measure a straight-line distance from a fixed point at your home to a fixed point at the school, then offer places to the closest children first until they run out. Other authorities measure a walking route or use a different method, which can give a different result for the same house. The School Admissions Code requires each admission authority to state clearly how it measures distance, so the school's own arrangements are the definitive source.
Because distance is usually the final tie-breaker, it only comes into play after the higher-priority groups have been placed. In a year with a large sibling intake, for example, fewer open places are left for distance, so the last child offered a place can live very close to the school. The method, and the exact home point used, are set out in each school's admission arrangements.
Catchment areas, priority areas, and feeder schools
"Catchment" is often used loosely to cover several different mechanisms, and they are not the same.
- A defined catchment or priority area is a mapped zone. Living inside it gives priority over children outside it within that criterion, after the higher-priority groups, but applicants inside the zone are still ranked against each other, usually by distance.
- A feeder school arrangement gives priority to children from one or more named primary schools, either on its own or alongside catchment or distance rules, as long as the link is transparent, reasonable, and set out in the arrangements.
- A pure distance rule has no zone at all. The effective catchment is simply however close you need to live in a given year to be offered a place.
Knowing which of these a school uses changes your strategy completely. A mapped catchment is usually more predictable than a distance-only cut-off, which can move noticeably with demand, but it can still change if the admission arrangements are redrawn.
Why the catchment cut-off can move each year
This is the point that catches families out. Where a school relies on distance, there is no permanent boundary. The effective catchment is set each year by the last distance offered, which is how far from the school the final child to receive a place lived that year. That figure shifts with the number of siblings applying, families moving house, and how popular the school is that year.
So a house that was comfortably inside the cut-off one year can fall outside it the next. Treat any catchment figure, including last year's last distance offered, as a guide to where you stand rather than a guarantee. The only reliable source is the published criteria and the order they are applied in.
How to check a school's catchment
There are three reliable steps, in order.
- Read the school's admission arrangements, published by the school or your local authority, to see whether it uses a catchment area, distance, feeder schools, or a mix, and exactly how it measures distance.
- Look at recent years' last distance offered for the school, which many local authorities publish, to get a realistic sense of how close you may need to live.
- Apply through your home local authority by the relevant normal-round deadline, or follow the in-year process if you are applying outside the normal round, naming several schools in order of preference, and remember that distance and catchment do not override the higher-priority groups.
If you think a school's arrangements are unlawful or unfair, you can object to the Schools Adjudicator, usually by 15 May in the year before the arrangements apply. Separately, you have a right to appeal a refused place. For the application process itself, see the GOV.UK guide on how to apply.
How FindMySchool helps
Catchment is really a question of distance and demand, which is exactly what FindMySchool makes visible. For schools across every local authority in England, we publish the last distance offered for each admission band, including the general distance, siblings, EHC plan, faith, feeder, and aptitude routes, so you can enter your postcode and see where you would stand. Because these figures come from previous years and move with demand, we show them alongside a clear reminder that they vary each year and do not guarantee a place.
- Use the school search and the map to find schools near a postcode and see how close they are.
- Let School Match build a shortlist that fits your family, then check each school's last distance offered before you list preferences.
- Planning the application itself? Read how primary school waiting lists work and our guide to when your child starts school.
Before you commit to preferences, do three things: read each school's admission arrangements in full, check its recent last distance offered for your address, and make sure your list includes at least one school you are confident of reaching on distance. That balances ambition with a realistic safety net.
Frequently asked questions
A catchment area is the part of an area a school gives priority to when it has more applicants than places. It is one of the criteria a school can use to decide who gets in, not always a fixed boundary, and it does not on its own guarantee a place.
