About these grades

Ofsted's report cards (from November 2025) grade each area on five steps and give no overall grade. Earlier grades come from a different framework; Ofsted says the two cannot be compared, so they are never converted here. Ofsted: "We normally inspect schools every 4 years or at any time if we have concerns." Methodology.
