What this guide covers
This guide covers eight fully selective grammar schools in Chelmsford, Colchester and the Southend/Westcliff area. Southend-on-Sea is a separate local authority from Essex County Council, even though it belongs in many families’ wider Essex school search.
For the normal school application, use your home local authority’s CAF. Test registration is a separate step. The first distinction to make is CSSE versus Chelmsford County High School for Girls, which runs a different assessment route.

These are Year 7 intakes. KEGS is a boys’ school at Year 7, although its sixth form is mixed. Do not infer a child’s entry eligibility from sixth-form descriptions.
The admissions split that matters most
| Route | Assessment context | What to do |
|---|---|---|
| CSSE | Shared English and maths assessment used by seven grammar schools in this guide. | Use CSSE’s correct-year registration, information guide and official familiarisation materials. |
| Chelmsford County High School for Girls | Its published 2027-entry process uses FSCE and is separate from CSSE. | Use CCHS’s own registration and familiarisation guidance; do not assume a CSSE registration covers it. |
CSSE also serves some selective places at schools that are not fully selective grammar schools. Its membership list and this guide’s eight grammar schools therefore answer different questions.
A shared score does not create a shared admission policy. Each CSSE school has its own rules for eligibility, priority groups, geography and allocation. CCHS has its own policy too. Check the actual entry year before selecting preparation materials or relying on a previous test format.
Chelmsford, Colchester, or Southend and Westcliff?
Chelmsford
KEGS and CCHS are different Year 7 intakes and use different assessment routes. For a girl considering CCHS alongside a girls’ CSSE school elsewhere, the family needs to understand both registrations and assessments.
Colchester
Colchester Royal Grammar and Colchester County High School for Girls are on different sites and have different Year 7 intakes. Check the last part of the journey from the station or bus stop, rather than relying only on arrival in Colchester.
Southend and Westcliff
The four schools share CSSE context but not an identical school site or admission policy. Compare the relevant boys’ or girls’ options, including their priority-area rules and the actual door-to-door trip. Southend and Westcliff labels do not make journeys interchangeable.
Compare schools and results carefully
- Identify eligibility and category
Read Year 7 intake, qualification, priority areas and evidence requirements at each school.
- Check historical figures precisely
A last-offered score needs its school, entry year, category and allocation round. It is not a guaranteed future cut-off.
- Use dated result measures
Compare the same GCSE or A-level measure and year. An unexplained composite score cannot establish which school is best for your child.
- Try the ordinary week
Include fares, station walks, clubs and support needs alongside curriculum and school visits.
Use rankings for the published measure shown there, then return to admissions and travel. This guide does not assign permanent ranks to schools.
Your Essex application record
Keep a shared CSSE test record where relevant and a separate CCHS record if applying there. For every school, save the correct-year policy, priority category and any separate forms. Check score-sharing or preference instructions rather than assuming registration finishes the application.
After results, use the CSSE score guide where applicable and read CCHS’s own result guidance for its route. Submit the home council CAF in genuine preference order, with acceptable alternatives. For visits, use open-day listings and confirm booking with the school.
A few more answers
Common questions
How many grammar schools are covered here?
Eight: two in Chelmsford, two in Colchester and four in Southend/Westcliff. Seven use CSSE; Chelmsford County High School for Girls has a separate route.
Is KEGS mixed at Year 7?
No. King Edward VI Grammar School in Chelmsford admits boys at Year 7. Its mixed sixth form does not make the Year 7 intake mixed.
Does CCHS use CSSE?
No. Chelmsford County High School for Girls publishes its own assessment and registration process; the 2027-entry route uses FSCE.
Is there one CSSE score that guarantees any Essex grammar school?
No. Interpret the score with each school’s eligibility, priority and allocation arrangements. Historic final offer scores also vary by school, category and round.
Do Southend residents apply through Essex County Council?
For the normal coordinated application, use the local authority where the child lives. Southend-on-Sea is a separate local authority; test registration remains separate.
