The CSSE 11+ 2027 entry: one exam, ten Essex schools

If your child is aiming at an Essex or Southend grammar school, one Saturday morning decides it. The CSSE 11+ is neither a GL paper nor a CEM one. The Consortium of Selective Schools in Essex writes its own, and it sets two papers, English and maths, for all ten schools.

That is the part the market keeps getting wrong. Advice written for parents tends to sort a family into “GL or CEM” within a paragraph, and Essex belongs in neither column. Getting it wrong costs in a particular way: it sends children into a term of non-verbal reasoning practice for a test that does not contain any.

What papers does the CSSE set?

The consortium describes itself in its own guide as a voluntary association formed in 1993, and says the same selective test is used by all ten of its schools, which saves a child whose parents prefer more than one from sitting several tests . Its description of what a candidate faces is short enough to quote whole:

Candidates will sit two tests. One in English and one in Mathematics.

The same guide says both are based on Key Stage 2 of the National Curriculum. Two papers are named and no others: there is no verbal reasoning paper and no non-verbal reasoning paper in the CSSE examination . Kent, by contrast, sets reasoning in three named sections, which is why the Kent Test asks for something quite different.

Paper	Length as published	How it counts
English	60 minutes, with 10 minutes additional reading time	Standardised, then weighted at half the total
Mathematics	60 minutes	Standardised, then weighted at half the total

The weighting is not a detail. CSSE says the final scores for the individual papers are mathematically standardised and weighted, each being worth 50% of the marks. A child who is strong in one subject and shaky in the other is carrying that gap straight into the total, at full weight, with no third paper to dilute it.

Age is handled after the event rather than in the paper. The consortium’s own age standardisation statement says the results of all candidates are analysed by date of birth to determine whether a statistical age adjustment is required . It publishes the resulting formula each year, and how those two raw marks become one standardised total walks through the arithmetic with the consortium’s own published figures.

What do the papers look like on the desk?

Here the guide is thinner than parents want, and being straight about that beats filling the gap. CSSE publishes no question count, no section structure and no statement about how answers are recorded.

Two things it does publish are worth more than the guesswork. The first is the equipment list: a child “need only bring a pen, pencil, ruler and eraser”, and highlighters, dictionaries, electronic calculators of any description and smart watches are all barred from the room . The second is a sample mark scheme for English continuous writing, which bands a piece of writing across ideas, vocabulary and spelling, grammar, structure and punctuation . A paper that carries a banded writing task is not one a child gets through by shading boxes quickly.

The consortium is also blunt about commercial practice books, saying they are “not of the same format as the 11+ papers” . Its own free familiarisation papers, on its own website, are the only samples anyone can honestly call the right shape. Start there, before anything bought.

Does one sitting cover all ten schools?

The saving the consortium describes is the whole point of it. On the registration form you nominate a single CSSE school as the test centre, and once that centre is confirmed the consortium says it cannot be altered. If a centre reaches capacity another is allocated, and if every centre fills on the main day a child is moved to the alternative Tuesday sitting .

The test centre is not a preference. Sitting the papers in one school’s hall is not an application to it: CSSE states that the only way to apply is to name the school on your council’s common application form .

Is registering for the test the same as applying?

No, and this is where families lose the year. The consortium gives the point a heading of its own: completing only the test registration form does not constitute a valid application for a place at a CSSE school . Two separate acts, two separate deadlines, two separate organisations.

Essex and Southend run their own schemes. Essex says its common application form lets parents express a preference for up to six secondary schools in order of preference, including schools outside Essex , and that applications for September 2027 entry can be made between 12 September and 31 October 2026 . Southend opens on 1 September 2026, with the same national closing date, and asks families to use all five of its preferences . CSSE adds that you may name as many consortium schools as your council’s limit allows, in a genuine order of preference.

How does one score reach ten schools?

The mechanism lives in the councils’ co-ordinated schemes rather than on the consortium’s website, and it explains exactly what a good score does and does not buy.

CSSE does not offer places. It marks, standardises, ranks, and hands the councils Order of Merit lists for the selective schools, drawn up in accordance with the schools’ own admission policies, by 18 December 2026 . Essex says it communicates directly with the consortium about the three CSSE schools inside its area; Southend treats the CSSE registration as, in effect, a supplementary information form . The council then matches those rankings against each family’s preference order and makes exactly one offer: the highest preference it can meet, with every higher preference going onto a waiting list and every unmet preference carrying a right of appeal .

A family in Essex names three CSSE schools first, second and third, and a non-selective school fourth. The child scores above the consortium minimum and is ranked high enough for a place at the second and third preference schools, but not at the first. What arrives on National Offer Day?

The usual wrong route

Parents expect one of two things: offers from both schools that ranked their child inside the intake, or a penalty for having named a selective school first. Neither happens. The second belief is the damaging one, because it pushes families into putting their real first choice second.

The method

1. The council works down the preference list in the order the family wrote it.
2. The first preference cannot be met, so that application is placed on the school’s waiting list.
3. The second preference can be met, so a place is allocated there.
4. Once a preference has been met, nothing below it is considered at all. The third preference is never reached, so no second offer exists to choose between.
5. The fourth preference is not looked at either.
6. The refusal at the first preference carries the right of appeal to an independent panel for that school.

Naming a selective school first costs nothing at the schools below it. Essex tells schools how many first, second, third, fourth, fifth and sixth preferences they received, but never what preference any individual child gave them.

Answer: One offer, from the second preference school. The first preference goes onto that school’s waiting list, with a right of appeal.In the paper: Two minutes.

What does the consortium’s floor actually promise?

CSSE publishes one number that binds all ten schools. Under the heading Minimum Score its guide states that offers are not made to any child who has scored under a total standardised score of 303, and adds that successful appeal places, and places awarded under special considerations criteria, sit outside that rule.

A floor is not a target. Above it, each of the ten schools applies its own admission policy to the children who named it, and those policies differ in ways that change the answer completely: some rank purely on score, some hold a priority area, some reserve places. This article restates none of them, because a per-school figure copied into an article goes stale the year it is published. Each school’s own page carries its arrangements, checked against what the school publishes.

Results reach families by email after the close of business on 12 October 2026, and contain the raw score for each subject as well as the overall standardised score, with the standardisation formula published on the consortium’s website shortly afterwards .

What are the dates for 2027 entry?

What happens	Date
CSSE registration opened	12 May 2026

National Offer Day	1 March 2027

The registration window is the trap in Essex, exactly as it is in Kent. It opens and closes in the summer term of the school year before the test, months before most families have begun thinking about secondary transfer at all .

What will the consortium not do?

All three sit in its own guide . It gives no special consideration to a child’s circumstances when papers are marked, and will not adjust scores. The CSSE schools have a joint policy of not re-marking test papers. And a confirmed test centre cannot be changed. Circumstances belong in front of an independent appeal panel at a chosen school, after offer day, and how results day and an appeal actually run sets out what that involves.

Which ten schools share the test?

School	What it is	Published admission number for 2027
Colchester County High School for Girls	Girls grammar	192
Colchester Royal Grammar School	Boys grammar	128
King Edward VI Grammar School, Chelmsford	Boys grammar	150
Shoeburyness High School	Mixed comprehensive, selective places only	28
Southend High School for Boys	Boys grammar	180
Southend High School for Girls	Girls grammar	224
St Bernard’s High School	Girls Roman Catholic bilateral, selective places only	30
St Thomas More High School	Boys Roman Catholic bilateral, selective places only	30
Westcliff High School for Boys	Boys grammar	185
Westcliff High School for Girls	Girls grammar	192

Three sit in Essex proper: Colchester County High School for Girls, Colchester Royal Grammar School and King Edward VI Grammar School in Chelmsford. The other seven are Southend schools: Southend High School for Boys, Southend High School for Girls, Westcliff High School for Boys, Westcliff High School for Girls, Shoeburyness High School, St Bernard’s High School and St Thomas More High School.

Together they publish 1,339 places for 2027 entry, but three of the ten are not grammar schools and their published number covers the selective block only. Shoeburyness is a mixed comprehensive with a set of selective places inside it, and St Bernard’s and St Thomas More are Roman Catholic bilateral schools whose selective places are a small part of a larger intake ranked on faith criteria. A child can meet the consortium floor and still be ranked under an entirely different set of rules at those three.

What should you do next for your child?

• Diarise the registration window rather than the test date. It opens and closes in the summer term before the papers are sat, and missing it costs the whole cycle.
• Prepare English and maths, evenly. Each is half the total, and there is no reasoning paper to rescue a weak one.
• Do not buy a general 11+ pack and assume it transfers. Work through the consortium’s own free familiarisation papers first, then practise in the same shape with two timed papers of the CSSE structure.
• Treat registration and application as two separate jobs with two separate owners, and put both deadlines in the same calendar.
• If your child is in Year 4 or early Year 5, the useful question is not which book to buy but when preparation should actually begin.

Then read the school pages before you rank your preferences: the consortium’s rules stop at the floor, and everything above it is set school by school. Each of the ten has its own record on our Essex school pages, dated and checked against what the school publishes.

Common questions

Is the CSSE 11+ a GL or a CEM test?

Neither. The Consortium of Selective Schools in Essex sets its own papers, and its own guide says candidates sit two tests, one in English and one in Mathematics, both based on Key Stage 2 of the National Curriculum. No verbal reasoning or non-verbal reasoning paper is named anywhere in it .

Does my child sit a separate test for each Essex grammar school?

No. The consortium says the same selective test is used by all ten schools, which saves families sitting several. You nominate one CSSE school as the test centre, and that choice does not limit which of the ten you may name on your council application form .

What is the 303 score?

It is the consortium-wide floor. CSSE states that offers are not made to any child who has scored under a total standardised score of 303, with successful appeals and special considerations placed outside it. It is a minimum to be considered, not the score that wins a place .

Is registering with CSSE the same as applying to the schools?

No, and it is where Essex families most often come unstuck. Registration enters your child for the test. The only way to apply for a place is to name the school as a preference on your home council’s common application form by the national closing date .

Can I ask for my child’s papers to be re-marked?

No. The CSSE schools have a joint policy of not re-marking test papers, and the consortium does not adjust scores for a child’s circumstances. Those circumstances can be put to an independent appeal panel at a chosen school after National Offer Day .
