How we rank these schools
  1. Headline Ofsted grade orders: Outstanding (1), then Good (2), then RI (3), then Inadequate (4).
  2. More recent graded inspection dates rank higher.
  3. Where available, we use the Quality of education sub-judgement as a tie-breaker.
  4. We may consider contextual signals (e.g., %FSM, roll size) to break remaining ties.

Ungraded visits don’t replace the last graded judgement.
