Maths school vs. grammar school sixth form

Both models select students academically, which is why they're often mentioned in the same breath — but the selection happens at different ages, on different criteria, and the resulting experience is quite different.

The core difference

Grammar schools select on general academic ability, usually via the 11-plus, and teach a broad curriculum from age 11 straight through to the end of sixth form. A maths school selects specifically on mathematical aptitude, at 16, and teaches a curriculum built entirely around maths and complementary STEM subjects.

Practically, that means a grammar school sixth form is a continuation — same school, same friends, same building, just a narrower subject choice within a broad curriculum. A maths school is a fresh start at 16: new school, new peer group, often a genuinely different commute.

If you're at (or considering) a grammar school already

Students at grammar schools with strong maths sixth forms sometimes ask whether moving to a specialist maths school at 16 is worth the disruption. The honest answer depends on how much your current sixth form can stretch you in maths specifically versus how much a specialist environment and cohort would add — and on how much the research paper's selection-effects caveat (see our research page) should temper any assumption that the maths school route is automatically stronger.

Grammar schools are themselves selective on general ability at 11, which means their sixth-form maths cohorts are already a self-selected group — worth bearing in mind when comparing outcomes between the two models, since neither is starting from an unselected baseline.
