Colchester Grammar Schools: Your Complete 11+ Guide

Colchester's Grammar Schools

Colchester has two grammar schools: Colchester Royal Grammar School (CRGS) for boys and Colchester County High School for Girls (CCHS). Both are among the highest-performing state schools in Essex and the wider East of England.

Colchester Royal Grammar School has a long history dating back to the reign of Henry VIII. It is renowned for its academic rigour, strong sciences provision and extensive extracurricular programme. The school typically admits around 120 boys into Year 7 each year.

Colchester County High School for Girls is equally prestigious, with outstanding results across all subjects and a strong reputation for music, sport and the arts. It also admits approximately 120 girls into Year 7 annually.

Both schools are part of the CSSE, which means they share a common entrance test with other grammar schools in Essex, including those in Southend and Chelmsford. This consortium approach means that sitting a single test can qualify a child for consideration at multiple grammar schools across the county.

The schools draw applications from a wide area, including north Essex, south Suffolk and parts of Cambridgeshire. This cross-border demand means that competition for places is significant. Families should attend open days at both schools to understand their individual character and decide which best suits their child.

The CSSE 11+ Exam Format

The Consortium of Selective Schools in Essex (CSSE) administers a common entrance test for all consortium grammar schools. The test has evolved in recent years and currently consists of papers covering English, mathematics and reasoning.

The English component includes comprehension, children read one or more passages and answer questions testing retrieval, inference, vocabulary and summarisation. There may also be a writing element, where children produce a short piece of creative or discursive writing.

The mathematics paper covers the Key Stage 2 curriculum with a focus on number, fractions, decimals, percentages, ratio, measurement, geometry and data handling. Multi-step word problems feature prominently, and mental arithmetic fluency is essential for working within the time limit.

The reasoning section may include verbal reasoning, non-verbal reasoning, or both, depending on the year. Question types follow standard GL Assessment formats, including sequences, codes, matrices, analogies and spatial reasoning.

The test is sat in September of Year 6 at designated test centres across Essex. Registration is handled online through the CSSE website, with the window typically opening in May and closing in late June. Results are released in October. EdifyPod Nexus covers all CSSE question types, giving children targeted practice for each component of the exam.

Preparing for the Colchester 11+

Because the CSSE test covers a broad range of skills, comprehension, writing, mathematics and reasoning, preparation needs to be comprehensive. Starting early and building gradually is far more effective than intensive cramming in the final weeks.

From Year 4, encourage daily reading across a range of genres. Children who read widely develop the vocabulary, comprehension skills and general knowledge that give them a significant advantage in the English paper. Discuss what your child reads with them, asking questions about character motivation, themes and the writer's craft deepens their analytical skills.

In mathematics, focus on building rock-solid arithmetic fluency. A child who can add, subtract, multiply and divide quickly and accurately will have more time for the complex problem-solving questions that carry higher marks. Fractions, decimals and percentages are particularly important and should be practised regularly.

Introduce reasoning practice at the start of Year 5. Both verbal and non-verbal reasoning require familiarity with specific question types, and children who encounter these for the first time in the exam are at a serious disadvantage. Work through question types systematically, building from untimed practice to timed conditions.

If the CSSE includes a writing component in your child's test year, practise timed writing regularly. Focus on planning, paragraphing, varied sentence structures and a strong vocabulary. Quality of expression and originality matter more than length.

Mock exams from spring of Year 5 onwards help build exam readiness. Find structured practice at edifypod.com/11plus to keep preparation consistent and targeted.

Admissions Timeline and Practical Tips

The CSSE admissions process follows a clear timeline. Registration opens on the CSSE website in May, with a firm deadline in late June. Parents must register for the test even if they have not yet decided which grammar schools to list on their application form, the test registration is separate from the school application.

The entrance test is held in mid-September at test centres across Essex. Children are allocated a centre based on their home address, and parents receive notification of the arrangements in August.

Results are released in mid-October, providing families with their child's standardised score. This score can then be used for applications to any CSSE grammar school, not just those in Colchester. The common application form must be submitted to Essex County Council by 31 October.

When listing school preferences, families in the Colchester area may wish to list both CRGS/CCHS and other Essex grammar schools if their scores are competitive. Including a non-selective school as a backup is strongly advisable.

National Offer Day is 1 March. Families who do not receive their preferred school can appeal, and the process is free and independent. Waiting lists also operate until at least December, so children can be allocated a place after the initial offer round.

One practical tip: ensure your child is familiar with the test centre environment. If possible, visit the area beforehand so the journey and surroundings are not completely unfamiliar on test day. Reducing unknowns helps manage anxiety. EdifyPod Nexus supports families throughout this process by tracking preparation progress and aligning practice with CSSE requirements.
