11 Plus Registration 2026: How and When to Register for Grammar School

The One Mistake That Cannot Be Undone in 11 Plus Preparation

Every year, a small number of UK families spend months preparing their child for the 11 plus exam — buying books, hiring tutors, building daily practice routines — and then miss the registration deadline. Their child cannot sit the exam that year. There is no appeal process for a missed 11 plus registration deadline. There is no late entry. The preparation year is lost entirely, and the child must wait twelve months for the next opportunity.

This is not a theoretical risk. It happens every year across every grammar school region in England. Registration deadlines for the 11 plus 2026 exam fall between April and July — months before the September exam sitting — and they are enforced without exception. Understanding exactly when to register, how the process works in your specific region, and what steps must be completed after registration is not optional knowledge. It is the most time-sensitive practical task in the entire grammar school entrance exam process.

This guide covers everything UK families need to know about 11 plus registration 2026 — region by region, step by step, with the deadlines that actually matter.

Registration and Application Are Two Completely Different Things

The single most dangerous misconception about 11 plus registration 2026 is that registering for the exam is the same as applying for a grammar school place. It is not. These are two entirely separate processes with different deadlines, different forms, and different authorities responsible for each.

Registration means signing your child up to sit the 11 plus exam itself. This is done directly with the grammar school, the regional consortium, or the local authority — depending on your region. Registration opens in spring and closes between April and July 2026 for most regions. This step gives your child permission to sit the test in September.

Application means applying for an actual school place through your home local authority's Common Application Form — known as the CAF. This deadline is fixed nationally at 31 October 2026 for secondary school applications. Missing this deadline has serious consequences for school place allocation. Completing your exam registration does not automatically submit your school place application. Both steps must be completed separately.

Many families assume that because they have registered for the test, the school place application is handled automatically. It is not. Mark both deadlines in your calendar today and treat them as equally non-negotiable.

How to Register for the 11 Plus 2026: Region by Region

11 plus registration 2026 works differently depending on which grammar school region you are targeting. There is no single national registration system. Each region — and in some cases each individual school — manages its own registration process. Here is how the major regions work.

For the Kent Test, children are registered through the Kent County Council online portal. Children attending Kent state primary schools are automatically registered by their school — parents do not need to take any additional action. Children attending schools outside Kent, or children in independent primary schools within Kent, must register manually through the KCC website. The registration deadline for the Kent Test 2026 typically falls in June. Check the Kent County Council admissions page directly for the confirmed 2026 deadline.

For the Buckinghamshire 11 plus, children attending Buckinghamshire state primary schools are also automatically registered by their school through The Buckinghamshire Grammar Schools consortium. Out-of-county applicants and children at independent schools must register manually. The Buckinghamshire registration deadline typically falls in May or June. Children who are automatically registered still need their parents to confirm participation — check with your child's school that this confirmation has been submitted.

For the SET exam in Sutton, registration is handled directly through the Sutton grammar school consortium. Parents must register their child themselves — there is no automatic registration process in Sutton. The SET exam registration 2026 deadline has historically fallen in late May or early June. Because five grammar schools share the same SET results, a single registration covers all five Sutton schools simultaneously. Missing this deadline means missing all five schools in one stroke — making the Sutton registration deadline the single highest-stakes deadline in any grammar school region.

For the CSSE exam in Essex, registration is managed through the CSSE consortium website. The CSSE covers ten grammar schools across Chelmsford, Colchester, and Southend. One registration covers all ten schools. The CSSE registration 2026 deadline typically falls in May. Children applying from outside Essex must register themselves regardless of school type.

For CEM 11 plus regions including Birmingham, Wiltshire, and Berkshire, registration is typically managed school by school. Each grammar school in these regions publishes its own registration process and deadline on its admissions page. In Birmingham, where competition is exceptionally high, registration windows can be short and close earlier than families expect. Check each target school's website individually rather than assuming a regional deadline applies.

What Information You Need to Complete 11 Plus Registration

Most 11 plus registration 2026 forms require the same core information. Having this ready before you open the registration portal prevents delays that could push you past a closing deadline.

You will need your child's full legal name exactly as it appears on their birth certificate or passport. You will need their date of birth, their current school name and address, their home address, and a working parent or guardian email address where confirmation and exam day information will be sent. Some regions — particularly those running the SET exam and CSSE exam — require you to upload supporting documentation for reasonable adjustments or special educational needs at the point of registration, not separately afterward. If your child has an Education, Health and Care Plan or requires exam access arrangements, check the specific documentation requirements for your region before the registration deadline. These supporting documents often have an earlier submission deadline than the registration form itself.

For out-of-county applicants in Kent and Buckinghamshire, you may be asked to provide evidence of your child's current school and a letter of support from the headteacher. Requirements vary and are published annually — always check the current year's guidance rather than relying on information from previous application cycles.

What Happens Immediately After Registration

Completing your 11 plus registration 2026 triggers several follow-up steps that families must complete before exam day. First, you should receive an email confirmation of registration. If this does not arrive within two working days, contact the registration authority directly. Do not assume your registration was successful without a confirmation reference number.

In some regions, registered children receive a candidate number and examination centre details by post or email several weeks before the exam. Keep this information in a safe place — your child will need their candidate number on exam day. If exam centre information has not arrived four weeks before the September sitting, contact the relevant consortium immediately.

The period between registration closing and exam day — typically July through September — is the most intensive preparation phase for most families. A child who is registered but underprepared is in a significantly stronger position than one who is prepared but unregistered. The registration is the prerequisite. Everything else — the books, the practice papers, the tutor sessions, the daily platform practice — is the preparation that fills the months between registration and results day.

AlphaTest's free diagnostic assessment is the ideal tool to begin immediately after completing registration. Within minutes it identifies exactly where your child stands across all four 11+ subjects — verbal reasoning, non-verbal reasoning, English comprehension, and maths — and produces a personalised preparation plan aligned to your target schools and the months remaining before exam day.

If You Have Already Missed the Registration Deadline

Missing the 11 plus registration deadline 2026 is a serious situation, but it is worth exploring every available option before accepting that your child cannot sit this year. Contact each target school's admissions office directly and explain the circumstances. In exceptional cases — serious illness, bereavement, or administrative error by the child's primary school — some regions do make provision for late registrations. This is not guaranteed and varies by region, but it is always worth asking.

If late entry is not possible, use the remaining time before the following year's registration window to ensure your preparation plan is strong and your registration is submitted well in advance of the 2027 deadline. Set a calendar reminder for February 2027 to begin monitoring registration opening dates for all target schools.

The most important takeaway from any missed deadline is a simple one: for the 11 plus 2026 exam, registration closes months before the September sitting. Mark the deadline for your specific region today, set multiple calendar reminders at four weeks and two weeks before that deadline, and treat it with the same urgency as the exam day itself.
