Essex is unusual among grammar-school areas: instead of buying a paper from GL or Cambridge, its selective schools write their own. The test is run by the Consortium of Selective Schools in Essex, known simply as the CSSE, and it stands out for being genuinely written rather than multiple choice, with a real emphasis on writing. This guide explains the two CSSE papers, the all-important continuous writing task, how the score out of 420 works, the key dates, and how to prepare. The CSSE sets its own exam, and Pip is not affiliated with it.
- The CSSE 11+ is the Essex grammar schools' own test, not a GL or CEM paper.
- Two written papers, English and maths, each about an hour, with children writing their own answers.
- The English paper includes a continuous writing task, so writing really counts.
- Papers are standardised and combined out of 420; a score above 303 is needed to qualify.
What is the CSSE 11+?
The CSSE is the Consortium of Selective Schools in Essex, a group of around ten grammar schools across Colchester, Chelmsford and Southend that share one entrance test. Rather than use an external board, the consortium writes its own papers. That gives the CSSE a distinctive character: it is written rather than multiple choice, it has no separate verbal or non-verbal reasoning papers, and it places unusual weight on a child's ability to write well under timed conditions.
What is in the CSSE 11+
Children sit two written papers, English and maths, each lasting about an hour:
- The English paper mixes comprehension (both multiple-choice and written-answer) with a continuous writing task that rewards structure, original ideas, ambitious vocabulary and varied punctuation.
- The maths paper covers the KS2 curriculum, including arithmetic and problem solving, with some non-verbal reasoning, and children write out their own answers.
- There is no separate verbal or non-verbal reasoning paper: the core is strong written English and worked maths.
Written, not multiple choice
This is the feature that sets CSSE apart from GL-based tests like the Kent Test or the Bucks Transfer Test. Children do not shade boxes on an answer sheet; they write their answers out, explain comprehension in their own words, and produce a full piece of writing. That makes clear handwriting, planning and timing genuinely important, and it rewards children who can think on paper rather than only recognise the right option.
How the CSSE is scored
Each paper is marked and standardised separately, with a small adjustment for age so younger children are not disadvantaged. The two scores are then weighted equally and combined into a total out of 420, 210 per paper. A standardised score above 303 is needed to be considered suitable for a grammar place. As with other areas, the most competitive schools set higher thresholds on top: Colchester Royal Grammar School, for example, uses a minimum around 320. For more on the scale, see our guide to standardised scores.
Key dates and which schools
The CSSE is sat on a Saturday in September, at the start of Year 6, for entry to Year 7 the following September. The consortium covers around ten schools, including Colchester Royal Grammar School, Colchester County High School for Girls, King Edward VI Grammar School in Chelmsford, the Westcliff and Southend high schools, and others across the county. Details and the exact date are set each year, so confirm them on the CSSE website. For how Essex fits the wider picture, see our guide to every 11+ exam type.
How to prepare for the CSSE 11+
Because CSSE is written and writing-heavy, the best preparation looks a little different from a GL area. Make wide reading and vocabulary a daily habit, and practise continuous writing regularly, focusing on planning, paragraphs and varied sentences rather than tricks. For maths, work on showing clear method and solving multi-step problems on paper, not just getting to an answer. Timed practice helps, since both papers reward children who can write fluently within the hour.
Build the English and maths CSSE rewards
Pip generates unlimited English and maths practice, with comprehension and vocabulary at the core, so the reading, writing and worked maths behind the CSSE papers become second nature.
Frequently asked questions
What is the CSSE 11+?+
The CSSE 11+ is the entrance test for the Consortium of Selective Schools in Essex, a group of around ten grammar schools across Colchester, Chelmsford and Southend. The consortium writes its own papers rather than using GL or CEM, with two written papers in English and maths.
What does the CSSE 11+ include?+
Two written papers, each about an hour. The English paper combines comprehension with a continuous writing task that rewards structure, ideas, vocabulary and punctuation. The maths paper covers the KS2 curriculum with problem solving and some non-verbal reasoning, and children write their own answers rather than choosing from multiple choice.
How is the CSSE 11+ scored?+
Each paper is marked and standardised separately, adjusted for age, then weighted equally and combined into a total out of 420 (210 per paper). A standardised score above 303 is needed to be considered suitable, and the most competitive schools, such as Colchester Royal Grammar School, set higher thresholds on top.
How is CSSE different from GL?+
GL is multiple choice and includes separate verbal and non-verbal reasoning papers. CSSE is written, has no standalone reasoning paper, and puts real weight on writing through its continuous writing task. It rewards clear written English and worked maths rather than quick multiple-choice technique.
