Grammar School vs Comprehensive School

If you are a parent in England and you've heard the words "grammar school" mentioned for the first time, the first question you're likely asking is: what exactly is the difference between a grammar school and a comprehensive school? The answer matters, because the two types of school operate on fundamentally different principles — and understanding that difference is the first step in deciding whether to pursue grammar school entry for your child.

What Is a Grammar School?

A grammar school is a state-funded secondary school that selects its pupils based on academic ability, assessed through the 11+ examination. Children typically sit the 11+ in September of Year 6, at around age 11, for entry to Year 7 the following September. Only those who score highly enough are offered places. Grammar schools are free to attend — they are state schools, and GOV.UK says all children in England between the ages of 5 and 16 are entitled to a free place at a state school — but there is an entrance test to get in.

In January 2022, around 188,000 pupils attended 163 grammar schools in England, 5.3% of state-funded secondary pupils. On the House of Commons Library's January 2022 count, only 35 local authorities had any grammar schools and around 60% of grammars were in just 11 of them; Buckinghamshire Council says there are 13 grammar schools in Buckinghamshire. The House of Commons Library defines highly selective areas as those where 25% or more of state-funded secondary school places are in state-funded selective schools. In London, Queen Elizabeth's School (QE Boys) describes itself as selective, non-denominational and non-fee-paying, and The Henrietta Barnett School admits Year 7 pupils by academic selection through a two-round entrance test, with a Published Admission Number of 120 for September 2027 entry.

What Is a Comprehensive School?

A comprehensive school is a non-selective state secondary school that admits pupils of all academic abilities. Most state-funded secondary pupils attend non-selective schools: grammar schools had 5.3% of state-funded secondary pupils in January 2022 (House of Commons Library). Each school's admission criteria are usually set by the school or local council, and may give priority to children who live close to the school, who have a brother or sister at the school already, or who are from a particular religion (for faith schools) — but not to academic ability, because state-funded schools are generally prohibited from selecting by academic ability.

Comprehensive schools vary enormously in quality. Averages favour grammar schools, but that is partly intake: after adjusting for prior attainment at key stage 2, the House of Commons Library says the difference between grammars and non-selective schools narrows. The key difference is that entry is not determined by academic ability.

Key Differences: Grammar School vs Comprehensive

Academic Performance

Grammar schools as a group tend to achieve strong GCSE results on average (Attainment 8: 74.1 in 2022, House of Commons Library). This is partly because they select academically able pupils, and partly because being surrounded by peers with similar academic motivation can support achievement.

However, this comparison requires care. Grammar schools' results are partly a function of intake, not just school quality. A comprehensive school serving an affluent area may achieve results comparable to a grammar, while a grammar school in an area of socioeconomic deprivation may see lower outcomes than people expect. Raw results should always be looked at in context.

Does It Cost Money to Get Into a Grammar School?

The school itself is free — grammar schools are state-funded and charge no fees. Getting in depends on passing an entrance test, and some families choose to prepare their child for it. This is not compulsory. Kent County Council's Kent Test pages point to resources to support your child, and The Henrietta Barnett School's admissions page links to GL Assessment familiarisation booklets for its first-round test. See our guide on private tuition for more detail.

Which Is Better: Grammar School or Comprehensive?

This depends entirely on your child and your local options. A grammar school is not automatically better for every child — it is better for academically able children who will thrive in a highly academic environment with peers at a similar level. For children who are academically able but thrive on a wider range of learning experiences, a strong comprehensive or an independent school might serve them better.

The most important questions to ask are:

• Is my child academically strong enough to pass the entrance test for the grammar schools in our area?
• How good are the comprehensives in our local area?
• Would my child enjoy a school where the expectation is fast-paced academic work across all subjects?
• Is the commute feasible? (Grammar schools often draw from wider areas than local comprehensives)

What About Grammar Schools vs Private Schools?

Grammar schools charge no tuition fees, while independent schools do: the Independent Schools Council's Census, taken in January 2026, reports average termly fees for day schools, excluding VAT, from £4,473 in the North West to £7,580 in London, and VAT at the standard rate of 20% applies to private school fees from 1 January 2025 (HMRC). Independent schools educate 6.3% of all pupils in England (560,300 in 2025/26, DfE). Separately, grammar schools had 5.3% of state-funded secondary pupils in January 2022 (House of Commons Library). For families who value academic rigour but cannot afford independent school fees, grammar schools represent an excellent option. However, ISC schools have smaller classes: a pupil-teacher ratio of 8.5 to 1, which the ISC Census 2026 describes as substantially lower than in the state-funded sector.

The Selective vs Non-Selective Decision: Practical Considerations

The decision between grammar and comprehensive schooling is rarely straightforward because it depends on a child's individual academic profile, geographic location, and how the family weighs different educational priorities. In areas where grammar schools exist, families effectively face two parallel secondary systems — selective state, non-selective state, and often independent selective schools as a third option.

For families considering the selective state route, the 11+ examination is the entry mechanism. Councils and schools point families to familiarisation or practice material so that a child can see the format before the test; in Buckinghamshire, for example, the dates for entry in 2027 show a Practice Test that was held on 8 September 2026 and the Secondary Transfer Test that was held on 10 September 2026. Our 11+ tuition pages cover the preparation process in detail, including which skills the test emphasises and how preparation timelines typically unfold from Year 4 onwards.

For families weighing grammar against independent selective schools, the calculus includes not just academic environment but also fees, bursary availability, co-curricular provision, and the specific culture of each school. ISC schools report a pupil-teacher ratio of 8.5 to 1 in the January 2026 Census, substantially lower than in the state-funded sector; grammar schools select their pupils on academic ability and charge no tuition fees. Where no grammar school is within reach, the comparison is between non-selective state schools and independent schools. Our admissions tests pages cover the range of tests used by selective state and independent schools, including the 11+, ISEB Common Pre-Test, and others relevant to secondary transitions.
