How do primary school admissions work in Lambeth?

I moved house to Tunbridge Wells in Kent about three years ago. At the time, my son was 1.5 years old and my wife and I didn't think about schools until it was too late to really do so properly. Bad parents, clearly.

There was much rushed reading of obscure PDF files on the council website, but ultimately we made our decision about where to buy without really being properly informed.

This experience led me to create AdmissionsDay.co.uk, and as well as learning a huge amount about how school admissions and catchments work, I’ve also learned that they're a bit of mystery to a lot of people. I made AdmissionsDay.co.uk to try and remove this mystery.

This article aims to describe how the admission process works for primary schools in the London borough of Lambeth.

1. Admissions criteria

Every school uses a set of criteria to decide which children to admit. There are a little over 60 primary schools in Lambeth, and currently about half of them follow criteria set by Lambeth council. The others are academies, free schools and religious schools and can set their own criteria.

In reality though, the criteria for almost all schools have a lot in common, and the majority of children will be admitted based on them being siblings of an existing pupil, or based on how close they live to the school.

But individual schools (the academies, free schools and religious schools mentioned earlier) can set their own criteria. For example Corpus Christi Catholic Academy in Brixton prioritises baptised Catholic children from specific parishes over others, and for at least the last couple of years it has filled all of its places under religious criteria.

If you’re considering applying to a school, you need to find and understand these criteria. If you purchase access to AdmissionsDay, you also get access to direct links to the admissions pages of around 95% of all schools that set their own admission policies.

An example

So, let’s imagine that a school has 60 places on offer and receives 344 applications. Imagine then that 24 of these applications are from brothers or sisters of existing pupils. This only leaves 36 places left for the other applicants. In fact, this is what happened at Henry Cavendish Primary School in Balham in 2017, which is one of the most popular schools in the area.

The remaining 284 applicants were then ranked by how far away they live from the school (the distance is measured in a straight line from house to school) and the top 36 are given places — all 36 lived within 360 metres of the school.

2. What about catchments?

For the majority of primary schools in Lambeth, there are no catchments — no predefined areas from which a school takes its pupils.

In fact, the geographical area from which a school admits its pupils changes every year.

In the example of Henry Cavendish above, the last child of the 36 admitted based on how far away they live, lived 0.22 miles from the school.

This distance represents a kind of effective catchment area for that year: if you’d lived closer you’d have got in. For most primary schools in Lambeth, this effective catchment is a circle that changes in size each year. An example for Henry Cavendish from 2016 is shown below.

These areas change year by year for each school, varying based on the number of places given to siblings and the popularity of the school. Sometimes they can change by a large amount, becoming smaller if there's a sudden influx of siblings one year, or bigger if a school increases its capacity.

With AdmissionsDay, we're trying to record these catchment circles for as many state primary schools as we can, so paying users of the site can see how they have changed over time.

A few schools in Lambeth don’t use straight line distance, but instead measure the walking distance from the school to your home, along streets with pavements. For the last couple of years, Dunraven school has even used “shortest walking route lit by street lighting”. Instead of circular catchment areas, this makes a much more irregular, jagged shaped catchment. We currently do not have the capability to show these catchment areas for schools using this method.

3. Why does all of this matter?

When you apply to a primary school in Lambeth, you have space to list up to six preferences — six schools that you would like your child to go to. The order you put these preferences in has no impact on how a school treats your application, but if your child is eligible to go to say both your first and second preference, you will only be offered the place at your first preference.

We're collecting the data on how many applications or preferences each school receives every year, so you can see how the popularity of a school has changed over time. For about 50% of primaries in Lambeth, we can also tell you how many places were taken each year by siblings.

It's important to understand the criteria and effective catchments of different schools for a couple of different reasons:

• If you're not planning on moving, you need to know at which schools your child actually has a chance of being offered a place, so you don't waste a preference on a school that's too far away to get into.
• If you're looking to change where you live, you need to know what the effective catchments have been in the past. It's not a fool-proof way of ensuring admission as they change every year, but it's a good guide, and much better than estate agents' typically hand-wavey claims about proximity.
