Getting into Colchester County High School for Girls
The CSSE 11+, the written exam the ten Essex consortium schools set for themselves: what it involves and what to do next, for entry in September 2027.

Registration for the September 2026 test closed on 19 June 2026. The consortium calls that deadline absolute and does not accept late registrations. Otherwise: 2 weeks to test day.

The test, in one look
Colchester County High for Girls sits the CSSE (Essex) 11+.
The CSSE (Consortium of Selective Schools in Essex) is a group of ten Essex grammar schools that write their own 11+ rather than buying it from a national provider. It’s a written exam, not multiple-choice: an English paper of 60 minutes (with 10 minutes’ reading time first) and a Maths paper of 60 minutes, with working shown and marks available for method. Of the major 11+ formats it’s the closest to a real school exam, and it rewards clear written answers in a way multiple-choice tests can’t.
CSSE is written rather than multiple-choice, and method earns marks, so handwriting a full answer is part of what is being tested. Online practice cannot rehearse that part, and we would rather say so: use past-style written papers for the writing itself. What our practice does cover is the underlying English and Maths the papers draw on, adaptively and at the right level, plus mocks in this school’s format so the shape of the exam is familiar.
The score, honestly
Two numbers are published, and they do different jobs. 303 is the consortium floor, below which no offer is made anywhere. 320 is CCHSG’s own condition for its reserved routes: looked-after girls, up to 20 Pupil Premium places and up to 10 Service Pupil Premium places. Everything else is rank order, 154 places counted from inside the 25 mile priority area and the last 38 open to any address. Living inside the area is worth a great deal here, but it is still a queue ordered by score.
How places are decided
192 places for September 2027. Reaching the required standard puts a child in the running; this order decides the rest.
Catchment: A priority area of 25 miles from the school in a straight line. You have to live inside it without a break from 31 October 2026 to the start of Year 7 for it to count.
EHCP naming the school with 320 or above, then: looked-after and previously looked-after girls scoring 320 or above; up to 20 Pupil Premium girls scoring 320 or above; up to 10 Service Pupil Premium girls scoring 320 or above who live in the priority area; then rank order of marks for girls in the priority area until 154 places are used; then the remaining 38 in rank order regardless of address.
What an EHCP is: an Education, Health and Care Plan, a legal document from your council for a child with special educational needs. Where a plan names a school, that school has to offer a place, so those places are taken out of the number above before anyone else is ranked. It is not a route most families can apply through.

The scores that actually won places
Schools and councils publish some of this and not all of it. The numbers below came from Freedom of Information requests, which anyone can make, and each one links to the reply it came from.
The published qualifying score is 303. That is the mark a child has to reach to be considered at all. It is not the mark that gets a place.
- For 2026 entry, the last place on the priority area route went to a child scoring 326, 23 marks above the qualifying score. Source
- For 2026 entry, the last place on the out of area route went to a child scoring 332, 29 marks above the qualifying score. Source
One year, not a promise about the next. The bar moves with how many children apply and how they score.
Across 2014 to 2024 the school heard 76 appeals and upheld 2.
How pupils here do at GCSE
This is based on how pupils at this school go on to perform in their GCSEs, five years after the 11+. Attainment 8 is their average result across eight subjects. Read it as a description of outcomes rather than of teaching: a selective school admits children who were already scoring well at ten, so a high position here reflects who the school takes in as much as what it does with them.
Scores from Compare school and college performance data in England, Department for Education, 2024/25, under the Open Government Licence v3.0. The Department publishes the scores and does not publish a ranking: the position above is ours, calculated over state-funded schools with a published score. See the full table.
One sitting, 10 schools
The same CSSE papers also cover these schools, which is worth knowing before you rank your preferences on the council form:
Common questions
No, and that is the thing to plan around. Both papers are written, so your child works answers out on the page and can pick up marks for method in Maths. Of the main 11+ formats it is the closest to a real school exam.
No. One sitting covers all ten consortium schools. You choose which of them to apply to later, by naming them in your genuine order of preference on your council application form, which closes on 31 October in the year of the test.
The consortium publishes one number: no CSSE school makes an offer to a child scoring under a total standardised score of 303. Each school then fills its places in rank order, so the mark that actually decided the last place is different every year and is only known after offers go out on 1 March. CSSE publishes a sheet of historical scores on results day to help you judge.
By email after close of business on 12 October for 2027 entry, allowing about 24 hours for delivery. Results always land before the 31 October council deadline, so you list your preferences already knowing the score.
There is a second date, the Tuesday after the main sitting (29 September for 2027 entry), for children whose religion does not allow a Saturday test or who are ill with medical evidence, and for other exceptional circumstances agreed with the CSSE office. It is not offered to fit around other authorities’ tests.
For 2027 entry, registration opened on 12 May 2026 and closed on 19 June 2026, and the consortium calls that deadline absolute. Missing it means no test that year, so register early and send any supporting paperwork afterwards.
Two weeks out is exactly when a timed mock helps.
PlusProgress mocks return a standardised score, the same currency the CSSE reports back, so you can see where she stands long before results day.
