If your child turns four before the end of next August, the next few months decide where they will start school. Priory's primary schools are popular, and the families who come through the process calmly are almost always the ones who read the rules early, checked last year's admission figures, and got their paperwork in order long before the deadline. Nobody enjoys the January scramble. You do not have to join it.

Here is how the round works, in plain terms, from the first day applications open to the moment you accept an offer.

The dates to put in your diary

Exact dates vary slightly between councils, so confirm them on your local authority's admissions page. The shape of the year, though, is consistent:

• Early September: applications open for the following September's reception intake.
• 15 January: the national closing date for on-time applications. This is the one date that genuinely matters.
• February to March: councils verify addresses and school criteria. Expect to be asked for documents.
• 16 April: national offer day. You receive one offer, from one school.
• Roughly two weeks after the offer: the deadline to accept or decline. Accept it even if you are appealing elsewhere.
• Around 20 school days after the offer: the deadline to lodge an appeal.
• Through to the end of the year: waiting lists stay open. Places do come up as families move.

Applications submitted after 15 January are still processed, but they are considered after every on-time application. In a competitive area, that effectively means the schools you wanted are full by the time your form is read.

How catchment areas actually work

A catchment area is not a guarantee of a place. It is one line in a school's list of oversubscription criteria — the order in which the school fills its places when more families apply than there are seats. Living inside the catchment usually puts you ahead of families outside it, but if the school is heavily oversubscribed, children living closest may still take the last places.

Three details catch parents out every year.

Distance is measured differently by different schools

Some schools measure a straight line from your front door to the school gate. Others measure the shortest safe walking route. A house that looks two streets away on a map can fall outside the cut-off if the walking route loops around a railway line. Check the school's own admissions policy rather than assuming.

Sibling priority is not automatic across the family

Many schools give priority to children with a brother or sister already at the school. Read the wording carefully. Some policies specify that the sibling must still be attending when the younger child starts, some restrict it to particular year groups, and some apply it only to certain schools in a federation. A nursery place at the school, a sibling at a nearby school, or a parent who works there are all separate categories with their own rules.

Where you live on the closing date is what counts

Councils assess your address as it stands at the application deadline. Moving in June rarely helps, and using a grandparent's address or a relative's postcode is treated as a false application — offers can be withdrawn, sometimes after a child has started. It is not worth the risk.

One habit that pays off: most councils publish the distance of the last child admitted to each school in previous years. Look up last year's figure for the schools on your list. It tells you far more than any rumour in the playground.

Applying: a step-by-step walkthrough

1. Apply through the council where you live. Even if the school you want sits in a neighbouring borough, your own council handles the form. You can list schools in other areas on it.
2. Read each school's admissions policy in full. Academies, free schools and faith schools often set their own criteria and their own supplementary forms. Missing a faith form can cost you a place.
3. Note the open days. Most Priory-area primaries run tours in the autumn term. Visiting in person tells you about the walk to school, the playground, and the feel of the place in a way no prospectus can.
4. List your schools in genuine order of preference. There is a stubborn myth that naming a popular school first damages your chances at your second choice. It does not. The system works through your list in order and offers you the highest-ranked school with a space. Listing only one school is the real mistake — it can leave you with a distant place you never wanted.
5. Gather your evidence early. You will usually need your child's date of birth, proof of address such as a council tax bill or tenancy agreement, and details of any sibling already at a school.
6. Submit online before 15 January and save the confirmation. Keep the reference number somewhere you can find it in April.
7. Answer any verification requests within days, not weeks. Councils cannot process a place they cannot confirm.

Common mistakes worth avoiding

• Assuming a nursery place at the school leads to a reception place. It usually does not.
• Sending the form to the school. Schools do not process applications; the council does.
• Leaving it to the final evening, when the portal is slowest and documents are hardest to scan.
• Forgetting to tell the council if you move between January and April.
• Declining an offer in protest while waiting for an appeal. Accept it, then appeal or stay on waiting lists. Accepting does not remove you from either.

After the offer: waiting lists and appeals

Waiting lists are ranked using the same criteria the school used in the first place, not by when you asked to join. Being first to ring the office does not move you up. Places do open up through the summer and into the autumn, so it is worth staying on the list for a school you genuinely want.

Appeals are handled independently of the school and the council. For reception, year 1 and year 2, infant class size rules make appeals harder to win, and the panel can only consider specific grounds. The paperwork is free to submit and the process is explained on your council's appeals page. If your situation involves a child with special educational needs, an education, health and care plan, or anything that might be legally complex, take advice from your council's admissions team or an independent adviser before you decide how to proceed.

Your next three steps

This week: find your council's primary admissions page, note the exact closing date, and download the list of last-placed distances for the schools you are considering. Before half term: book two or three open day visits and read each school's admissions policy, particularly the oversubscription criteria. By December: draft your list of preferences with your child's needs in mind — the walk to school, the morning routine, siblings — and have your proof of address ready to upload.

Admissions rules are set by each council and each school, and they do change from year to year. Treat this as a guide to how the process works, not as a substitute for the current published policy. Check it directly, and if anything is unclear, ring the admissions team and ask. They answer this question every day.
