What does "superselective" mean?

“Superselective” gets used constantly in 11+ forums, tutoring guides, and newspaper league tables. It has no official definition. The Department for Education doesn’t use the term. Neither does Ofsted. When we researched the full list of England’s 163 grammar schools, we specifically went looking for an authoritative, school-by-school classification — checking the Sutton Trust, FFT Education Datalab, Comprehensive Future, and the House of Commons Library’s own grammar school briefing — and none of them names individual schools. They all define selectivity at the local authority level, not the school level. The commonly cited figure of “around 25 superselective schools” traces back to secondary analysis of 2023 DfE data, not a published list with named schools and a stated method.

So every superselective determination on this site is our own judgement call, made from primary evidence, school by school — and we try to show our working rather than asserting a label.

The test we actually apply

We look for evidence that a school draws from a meaningfully narrower or higher-scoring band than an ordinary grammar-eligible cohort, in one of two ways:

1. A documented score requirement above a shared baseline. Dartford Grammar School requires most of its intake to score 40 points above Kent’s standard grammar-qualifying threshold — a number we could check directly against the school’s own admissions arrangements. That’s about as solid as evidence gets.
2. No catchment plus extreme, demonstrated oversubscription. The Henrietta Barnett School accepts applicants from anywhere, and its own paperwork records over 3,100 applications for 120 places in a recent year — more than 25 to one. That ratio is doing the work, not just the absence of a catchment map.

Where it gets genuinely contested

A no-catchment, rank-by-score admissions mechanism looks superselective on paper. But the same mechanism can produce very different real-world selectivity depending on how many people actually apply — and we found cases in our own research where that mattered:

• Torquay Boys’ Grammar School has no catchment and ranks purely by score, which matches the mechanism above. But the local council’s own admissions data puts demand at roughly 1.8 applicants per place — nowhere near Henrietta Barnett’s ratio — while a sibling school with an almost identical mechanism was independently assessed as not superselective. We reported that as unresolved rather than picking a side.
• Altrincham Grammar School for Boys carries a strong local reputation as one of the tougher schools to get into — but its own published qualifying score turned out to be numerically identical to Urmston Grammar’s, the school in the same consortium most often described as the least selective. Reputation and documented evidence pointed in opposite directions, so we went with the evidence.
• All four Bournemouth/Christchurch/Poole grammar schools share one entrance test and none of them publishes a qualifying score at all — so for that whole group, we report the classification as genuinely unresolved (null) rather than guessing either way.

What this means for you

If a school’s page here says “not established” or flags the superselective field as contested, that’s not us being cagey — it means the evidence didn’t clearly support a confident answer either way, and we’d rather tell you that than manufacture false precision. See our methodology for the full verification standard this applies to every fact on the site, not just this one.
