01 · How it works

How Buckinghamshire grammar admissions work.

Buckinghamshire’s grammars share a single entry test — the Secondary Transfer Test (STT), set for The Buckinghamshire Grammar Schools (TBGS) consortium. Children sit it in mid-September of Year 6; you register over the summer beforehand. The qualifying standard is a standardised score of 121.

You then list your preferred grammars on your home council’s application form by 31 October. Offers go out on 1 March.

Qualifying makes a child eligible across the county — but each school then applies its own catchment area and distance rules to decide who actually gets a place.

02 · Catchments

How Buckinghamshire catchment areas work.

Every Buckinghamshire grammar uses a catchment area: a school-specific zone in which living gives you priority, with straight-line distance breaking ties inside it. None are purely super-selective on score.

Because the county is wholly selective, the practical question is less “will my child qualify” and more “which school’s catchment am I in” — the areas overlap and leave gaps that aren’t obvious from a glance at a map.
