Families understandably spend months thinking about Maths, comprehension and mock scores. Yet an administrative mistake can matter more than any worksheet. The 11+ has no single national registration process, and the steps for a test, a consortium and the later secondary-school application can be different.
The safest rule is simple: treat admissions administration as a separate project from revision.
Mistake 1: assuming the school will register your child
In some areas, parents must register directly for a selective test. In others, arrangements involve a local authority, consortium or individual school. Do not assume a primary school will handle it automatically.
Check the official admissions page for every target school and note who actually runs the test.
Mistake 2: relying on last year's dates
Registration windows can change. An old forum post, tutor handout or sibling's timeline may be close enough to create false confidence but wrong enough to cause a problem.
Use current official information for the admission year your child is entering.
Mistake 3: confusing test registration with the school application
Sitting an 11+ test and naming a school on the Common Application Form are not necessarily the same step. In many cases, families must complete both parts at different times.
Put both deadlines in the same calendar before you do anything else, because they sit in different months and are run by different bodies. Check the key 11+ registration and exam dates
Create separate calendar entries for test registration, test day, result timing and the local authority school application deadline.
Mistake 4: registering for the wrong test or consortium
If you are considering schools in more than one selective area, there may be separate tests or shared arrangements. Verify which test feeds which schools.
Do not assume that one 11+ result automatically applies to every grammar school you like.
Mistake 5: ignoring catchment or residency evidence
Some schools use distance, catchment or priority-area rules. The evidence required and the date at which an address is assessed can matter.
Read the admissions policy rather than relying on estate-agent language such as “grammar-school catchment”. Only the official policy tells you how the address is treated.
Mistake 6: leaving reasonable adjustments too late
If your child may require access arrangements or reasonable adjustments, check the process and evidence requirements early. Schools or test authorities can have specific deadlines and documentation rules.
Do not wait until the week before the exam to raise a need that requires formal review.
Mistake 7: using one email address without monitoring it
Confirmations, test details or requests for information may arrive by email. Use an address you check regularly and save confirmation messages.
Add important dates to a calendar instead of relying on the inbox as your reminder system.
Mistake 8: not checking the final confirmation
When registration is complete, verify the child's details, test centre, date and any instructions. If something looks wrong, contact the official admissions team promptly.
Build a one-page admissions checklist
For each school, record:
- official admissions URL;
- test provider or consortium;
- registration opening and closing dates;
- evidence required;
- test date;
- result date if published;
- school application deadline;
- catchment/priority notes.
Keep revision scores on a different page. Administration and attainment are separate risks.
Understand the whole 11+ process
EduArchives' parent guide explains the main journey from registration through testing, school applications, offers, waiting lists and appeals. Use it as an orientation, then verify the exact current rules with the relevant authority.
Frequently asked questions
Is there one national 11+ registration deadline?
No. Dates and processes vary by area, consortium and school.
Is registering for the 11+ the same as applying for a grammar school place?
Not necessarily. Families may need to register for a test and later complete the normal secondary-school application process.
Where should I check dates?
Use the official school, consortium or local-authority admissions information for the relevant entry year.
