Best grammar schools in Essex 2026

Essex is one of the larger surviving grammar school counties in England, with eight state grammar schools spread across Colchester, Chelmsford and Southend. Most of them use the CSSE entrance exam, taken on a single Saturday morning in September of Year 6.

This guide walks through the eight schools, how admissions work in practice, the catchment quirks that catch parents out, and a sensible way to prepare without burning your child out. We've tried to be honest where Essex differs from the picture painted by national 11+ guides – it isn't quite Kent, and it isn't quite London.

There are eight maintained state grammar schools in Essex, plus a handful of borderline cases (Westcliff and Southend sit in the Southend-on-Sea unitary authority, but many parents still group them with Essex). Some 11+ guides count up to 11 schools by including selective Catholic schools in Southend (St Bernard's, St Thomas More) or partially-selective options like Shoeburyness High, so the headline number depends on definition. They split into three clusters by town: Colchester, Chelmsford and the Southend area.

Chelmsford County High School for Girls is the odd one out. It runs its own FSCE entrance exam rather than the CSSE, which means parents applying to both CCHS and a CSSE girls' school in 2026 need to sit two separate tests. CCHS is a destination school in its own right and is consistently among the strongest performing girls' grammars in the country.

A few selective Catholic schools in the Southend area (St Bernard's, St Thomas More) also use CSSE-style entry. They're sometimes counted in Essex 11+ guides and sometimes not, depending on whether the author is going by ownership or geography.

The CSSE (Consortium of Selective Schools in Essex) runs a single shared entrance exam for most Essex grammars. Children sit it once and the result is shared across all the schools they've applied to inside the consortium. This is a real time-saver compared with counties where each school runs its own test.

The exam is taken on a Saturday morning in mid-September of Year 6. Children sit two papers: English (60 minutes plus 10 minutes' reading time, with comprehension and a creative writing task) and maths (60 minutes, mixing arithmetic, word problems and multi-step questions). There is no separate verbal or non-verbal reasoning paper, unlike the GL Assessment tests used in some other counties. Both papers follow the KS2 national curriculum but stretch into Year 6 / early Year 7 territory.

A small number of Essex-borderline schools that sit close to London (notably Redbridge and Havering grammars) use GL Assessment-style tests rather than CSSE. If your child is also looking at schools like Ilford County High, you'll want to plan for two test formats rather than assuming one will cover both.

Each Essex grammar publishes its own oversubscription criteria. The detail varies more than parents often realise, but the broad pattern is the same: After looked-after children and any sibling priority, places go to qualifying applicants by either rank order of score or by distance from the school, or a combination of the two.

The Chelmsford and Colchester schools tend to lean on distance-banded criteria, with priority bands extending several miles from the school gate. The Southend schools have a tighter, more competitive catchment. Westcliff High for Boys publishes a chart of the previous year's furthest successful applicant, and in recent years that has sat well under three miles for the inner priority band.

This is among the most important things to check before paying for tutoring. A high CSSE score doesn't guarantee a place if you live outside the catchment band, especially in Southend.

A common mistake is treating the CSSE test as the application. It isn't. You still have to list grammar schools on your local authority's Common Application Form by 31 October. If you skip that step, you can score brilliantly and still end up with no offer at a selective school.

Sensible prep for the CSSE looks like this: Build a habit of daily reading in Year 4 and 5 (mostly fiction, but stretch into newspaper articles and short non-fiction by Year 5), shore up KS2 maths arithmetic so your child has fast, accurate written and mental methods, and do timed practice papers in the last six months before the test.

The English paper rewards children who read for pleasure. The comprehension passages aren't unusual in difficulty, but the writing task is where confident readers pull ahead – they have the vocabulary, sentence variety and reference points that a few months of intense tutoring can't really manufacture.

For maths, the focus areas worth practising specifically are: Fractions, decimals and percentages; word problems with multi-step working; ratio and proportion; basic algebra (simple equations and substitution); and the kind of two-step reasoning question where you have to spot what the question is asking before doing the maths.

Honestly, it depends. Most successful CSSE applicants have done some form of structured 11+ prep, whether through a tutor, an online platform, or a parent working through past papers at the kitchen table. Whether you pay for it is a question of time, budget and your child's working style.

If your child is already reading widely and the maths basics are solid, a few months of weekly past-paper practice from January of Year 5 onwards is usually enough. If there are real gaps – particularly in written English – starting earlier and getting an outside view is reasonable. What rarely helps is panic-tutoring four nights a week from September. Children who reach the test in October already exhausted tend to under-perform on the day.

Most Essex grammars are heavily oversubscribed. A child who scores well but lives outside the catchment can miss out on the school you applied for and still end up at a strong comprehensive in your area. Essex non-selective state schools include several Ofsted Outstanding-rated all-throughs and academies, and a few have results that hold their own against the grammars on Progress 8 measures.

If the appeal route matters to you, read the school's published admissions arrangements before September. Appeals against non-selective decisions at a grammar are very hard to win on academic grounds alone; appeals on catchment / distance grounds need supporting evidence and are usually heard in the spring.
