How to Apply: Step by Step
1. Apply Through Your Home Local Authority
You apply through the online admissions portal of the local authority where your child lives - not where your preferred schools are located. This catches a lot of parents out. If you live in Southwark but want to apply to a school in Lewisham, you still apply through Southwark's portal.
Search for your council's admissions portal, create an account, and work through the form. Most councils send a reminder to parents of Year 6 children in state schools, but if your child is in an independent school or is home-educated, that reminder may not reach you.
2. Name Four to Six Preferences
Every local authority asks you to name schools in order of preference - typically between four and six, depending on where you live. Use all the spaces available. Leaving preferences blank does not help you; it just reduces your options if your top choices are oversubscribed.
You are not limited to schools in your home local authority. You can name schools in neighbouring boroughs, and your home LA will forward those preferences to the relevant schools.
3. Gather Supporting Evidence
Some schools require additional documentation to process your application - proof of address, baptism certificates for faith schools, or a doctor's letter for medical priority. Check each school's admissions criteria carefully before the deadline, because evidence submitted late may not be considered.

How Preferences Work (and the Biggest Misconception)
This is the part most parents get wrong, and it genuinely matters.
Your preferences are considered simultaneously, not sequentially. Each school on your list assesses your child against its admissions criteria without knowing where it sits in your preference order. If your child qualifies for more than one school, you are offered the one ranked highest on your list.
The practical consequence: there is no penalty for putting a popular or selective school first. Naming your dream school at number one does not harm your chances at your safety school. The "equal preference" system was introduced precisely to stop parents from gaming the list in this way.
What you should do is list schools in your genuine order of preference, with at least one school you are confident your child will qualify for further down the list.

Grammar Schools: Extra Steps Required
If your child sat the 11-plus in September 2025, you still need to name the grammar school on your LA application. Passing the 11-plus does not automatically put your child in the running - you have to name the school explicitly.
Check whether you need to register your child's 11-plus result with the school directly as well. Some grammar schools require this separately from the LA process. If you are unsure, contact the school's admissions team now rather than after the deadline.
Note that 11-plus tests happen in September, so by the time you are reading this, that window has passed for 2025 entry. If your child sat the test, you should already have their result. If they did not sit it, grammar school entry for September 2026 is no longer an option through the standard route.

Faith Schools: Supplementary Information Forms
Many faith schools require you to complete a Supplementary Information Form (SIF) in addition to the LA application. These forms are submitted directly to the school - not through the council portal - and they often have their own deadlines, which may be the same as or earlier than 31 October.
SIFs typically ask for details about religious practice: how regularly your family attends services, the name of your priest, minister, or imam, and a supporting reference. Schools use this information to rank applicants within their faith criteria.
Missing the SIF means the school cannot assess your child under faith criteria. You would still appear on the LA application, but you would likely be ranked well below applicants who completed both forms.
Check every faith school on your list carefully. The school's own admissions policy, usually published on its website, will tell you whether a SIF is required and where to send it.

National Offer Day: 1 March 2026
On the morning of 1 March 2026, you will receive your offer by email or through your LA's online portal. Most families find out between 7am and 9am, though councils set their own timings.
You will be offered one school - the highest-ranked school on your list for which your child meets the admissions criteria. If your child qualifies for none of your preferences, the LA is obliged to find a place, but it may not be a school you named.
Take a breath before you do anything. Read the offer letter carefully, including any instructions about deadlines for accepting.

If You Don't Get Your First Choice
Not getting the school you wanted is genuinely upsetting, and it happens to a lot of families. You have two main options.
Waiting lists. Most oversubscribed schools maintain waiting lists after offers go out. Ask your LA how to add your child to a waiting list - in many areas you need to do this actively rather than being added automatically. Children move up and down waiting lists as families accept and decline offers, so a position of 15 in March can become an offer by July or even September.
Appeals. You have the legal right to appeal against any refusal. You need to lodge your appeal within a set window (usually around 20 school days after the offer date). Appeals are heard by an independent panel and are worthwhile where there are strong grounds - a medical need, an error in how the criteria were applied, or a compelling case that the school can accommodate your child without harm to existing pupils.
Use School Signal to check a school's historical admissions data, see how close the cut-off distances have been in previous years, and compare nearby schools. The more information you have going in, the clearer your options become.

One Final Reminder
31 October 2025. That is the date. Apply through your home local authority's online portal, list up to six preferences in genuine order of preference, and check every school on your list for SIFs or additional evidence requirements.
The earlier you apply, the more time you have to spot any problems before the deadline closes.
