Area guide · entry in September 2027The 11 plus in Essex: the CSSE test and grammar schools
The Essex 11 plus (eleven plus) is, for most families, one exam: the CSSE test, sat on one Saturday in September and used by ten grammar and partly selective schools in Colchester, Chelmsford, Southend, Westcliff and Shoeburyness. Chelmsford County High School for Girls is the exception, with its own entrance test. The CSSE is unusually open about the numbers: there is a published minimum score below which no offer is made, and several schools publish the scores that actually won a place.

Essex at a glance
- CSSE exam Saturday 19 September 2026: English and maths, an hour each. No verbal or non-verbal reasoning.
- The floor: 303 No CSSE school offer below a total of 303. Popular schools need far more: KEGS's lowest local offer for 2026 was 353.5.
- Apply by 31 October 2026 Registering for the test is not applying. Name the schools on your home council's form, in your real order.
- Eleven schools, two tests Ten schools use the CSSE test. Chelmsford County High School for Girls sets its own.
What the test covers
English and maths only, one hour each, based on the Key Stage 2 curriculum, with no separate verbal or non-verbal reasoning paper. KEGS describes the English paper as comprehension, grammar and vocabulary questions and two pieces of creative writing, so writing practice matters as much as the questions.
Good places to start: comprehension, word classes, punctuation, long multiplication, fractions of amounts, percentages, ratio and proportion.

Essex grammar schools: places and how they are given
One CSSE examination counts for the first ten schools below. Most give places in order of score, with a set number kept for children living nearby. Three are partly selective: only some of their places go by the test.
| School | Town | Year 7 places | Who gets a place |
|---|---|---|---|
| Colchester County High School for Girls | Colchester | 192 | Girls, by score: 154 places for girls living within 25 miles, 38 for girls from anywhere. Up to 20 for pupil premium girls scoring 320 or more. |
| Colchester Royal Grammar School | Colchester | 128 | Boys, by score only, with no catchment area. Up to 12 for looked-after or pupil premium boys scoring over 320. |
| King Edward VI Grammar School (KEGS) | Chelmsford | 150 | Boys, by score: 120 for boys living within 12.5 miles, about 30 for boys from anywhere. |
| Southend High School for Boys | Southend-on-Sea | 180 | Boys who pass, by score: up to 150 for SS0–SS9 postcodes, 30 for outside. |
| Southend High School for Girls | Southend-on-Sea | 224 | Girls who pass, by score: up to 179 for SS0–SS9 postcodes, at least 41 for outside. |
| Westcliff High School for Boys | Westcliff-on-Sea | 185 | Boys who pass, by score: up to 148 for SS0–SS9 postcodes, 37 for outside. |
| Westcliff High School for Girls | Westcliff-on-Sea | 192 | Girls who pass, by score: up to 154 for SS0–SS9 postcodes, the rest for outside. |
| Shoeburyness High School | Shoeburyness | 310 | Partly selective: up to 28 places for children in its priority area scoring 303 or more; the rest by other criteria. |
| St Bernard's High School | Westcliff-on-Sea | 175 | Catholic girls' school, partly selective: up to 30 places for girls in SS0–SS9 who pass; the rest by faith criteria. |
| St Thomas More High School | Westcliff-on-Sea | 180 | Catholic boys' school, partly selective: up to 30 places for boys in SS0–SS9 who pass; the rest by faith criteria. |
| Chelmsford County High School for Girls | Chelmsford | 180 | Its own test, not CSSE. 144 places for girls within 12.5 miles (up to 30 for pupil or service premium girls), up to 36 from anywhere. |
Places are each school's published admission number for September 2027, from its own admission arrangements. Looked-after children and children with an EHCP naming the school come first everywhere; the details of each school's priority places are in its arrangements.
The part most families need
The number that decides everything: 303
CSSE publishes a floor, and it is unambiguous. No CSSE secondary school offer is made to any child who has scored under a total standardised score of 303. Southend's admission booklet explains the pass mark as one set each year so that the entrance standard stays comparable with 1990 to 1994.
Places awarded on appeal, and places awarded under special considerations criteria, sit outside that figure.
303 is a floor, not a pass mark that guarantees anything. At the most popular schools the score that actually won a place was far higher, as the table below shows. The score needed at each school depends on demand that year and is only known after offer day in March.
- On results day CSSE publishes a guidance sheet of historical data, showing what scores were needed in previous years at each school. It is explicitly historical — there is no guarantee attached to it.
- CSSE's own advice is that it may still be worth applying to a school even if your child scored below the lowest mark recorded there in previous years, because the picture changes every year.
Scores that won a place in recent years
Three schools publish the lowest score that was offered a place on offer day. They show how different the schools are: close to 303 for local girls at Westcliff High School for Girls, over 350 at KEGS.
| School | Entry | Living nearby | From further away |
|---|---|---|---|
| King Edward VI Grammar School | September 2026 | 353.5 (within 12.5 miles) | 370.1 |
| Colchester County High School for Girls | September 2025 | 323 to 324 (within 25 miles) | 332 to 333 |
| Westcliff High School for Girls | September 2025 | 306.7 (SS0–SS9) | 345.9 |
| Westcliff High School for Girls | September 2024 | 303.3 (SS0–SS9) | 346.9 |
Lowest scores offered on offer day, as each school publishes them. KEGS's figures are for boys without pupil premium or looked-after priority. Some places are offered later as families decline: CCHSG's lowest eventual offer for 2025 was 318 to 319. The other schools do not publish cut-offs on their own sites; CSSE's guidance sheet covers them.
What is in the papers
Candidates sit two papers on the day, one in English and one in mathematics. Both are based on Key Stage 2 of the national curriculum, which makes this a curriculum test rather than a reasoning test.
- English
- Sixty minutes, with ten minutes of additional reading time. KEGS describes it as comprehension, grammar and vocabulary questions, and two pieces of creative writing.
- Mathematics
- Sixty minutes, on the Key Stage 2 maths curriculum.
- Marks
- KEGS gives 60 marks for each paper.
- Scoring
- The final scores for the individual papers are mathematically standardised and weighted, with a statistical age adjustment where one is required.
- Change worth knowing
- From September 2024, which was the 2025 entry round, the English paper no longer contains Applied Reasoning questions.
Registering is not applying
The CSSE registration form registers your child to sit the examination. It is not an application to any school. You can only apply by naming the schools as preferences on your home council's common application form, which opens on 12 September and closes on 31 October.
The order of your preferences matters. Essex County Council offers the highest preference that can be met. If your child scores well enough for a grammar school but you named another school above it, and that school can offer a place, you will be offered the higher one. Essex asks families to use all six preferences.
- Your child's name, date of birth and address on the CSSE form must match your council application exactly, or the result cannot be matched to the application.
- You nominate one CSSE school as a test centre. That choice does not affect which schools can consider your child.
- Children from outside Essex can sit the test: KEGS, CRGS and Colchester County High School for Girls all say so in their arrangements. Out-of-area places are fewer, and usually need a higher score.
- If you move house, Essex accepts evidence of the new address until 20 November 2026 for the first round of offers.
- Several CSSE schools reserve places for children on free school meals, entitled to Pupil Premium, or who are or have been in social care. This must be declared on the CSSE registration form.
No re-marks, and no special consideration in the marking
CSSE does not give special consideration to a pupil's circumstances when papers are marked, and scores are not adjusted afterwards. The consortium schools also have a joint policy of not re-marking test papers.
Circumstances are heard instead by an independent appeal panel at the schools you have chosen, after offer day on 1 March 2027.
- That is why the 26 June deadline for special adjustments matters so much: adjustments are arranged before the test, because nothing is adjusted after it.
- Children with an Education, Health and Care Plan who want a grammar school place must sit the test like everyone else: register with the CSSE and include the grammar schools on the application. If the score is high enough, Essex names the school in the plan.
Chelmsford County High School for Girls: a separate test
CCHS is the one Essex grammar school outside the CSSE. It uses the FSCE test (Future Stories Community Enterprise), which covers subjects across the Key Stage 2 curriculum up to the Year 5 programme of study, plus a creativity task. The school says it has multiple-choice and written questions, and girls must reach an eligible score in each part.
- For September 2027 entry, registration ran from 13 April to 3 June 2026, the test was on Thursday 3 September 2026, and results come by email in mid-October.
- There are no practice papers, only a familiarisation guide, and the test can be taken once.
- A girl who wants both CCHS and a CSSE school has to register for, and sit, both tests.
Getting there
The CSSE runs its own buses to all of its schools, with a termly ticket; families offered a place are sent an information pack. Essex provides free transport to a selective school for children from low-income families who live two miles or more away.
Questions parents ask
Does the Essex 11 plus include verbal or non-verbal reasoning?
No. The CSSE test is English and maths only, one hour each, based on the Key Stage 2 curriculum. There is no separate verbal or non-verbal reasoning paper.
What score do you need to pass the Essex 11 plus?
No CSSE school makes an offer below a total standardised score of 303, but that is a floor, not a guarantee. The score that wins a place depends on the school: King Edward VI Grammar School's lowest local offer for 2026 entry was 353.5, while Westcliff High School for Girls offered local girls places from 306.7 for 2025 entry.
Which schools use the CSSE test?
Ten: Colchester County High School for Girls, Colchester Royal Grammar School, King Edward VI Grammar School, Southend High School for Boys and for Girls, Westcliff High School for Boys and for Girls, and the partly selective Shoeburyness High School, St Bernard's High School and St Thomas More High School. Chelmsford County High School for Girls uses its own test.
Can children who live outside Essex sit the 11 plus?
Yes. KEGS, Colchester Royal Grammar School and Colchester County High School for Girls all say the test is open to children from outside the county. Most schools keep most of their places for children living nearby, so out-of-area places usually need a higher score.
When are the Essex 11 plus results?
For September 2027 entry, CSSE emails results after the close of business on Monday 12 October 2026. Chelmsford County High School for Girls emails its own results in mid-October.
Does registering for the test mean we have applied?
No. You still have to name the schools on your home council's application form by 31 October 2026, in your genuine order of preference.
