Reading the scores
Bands out of 100
Every category, sub-criterion and composite total across this issue uses the same six-band editorial palette. Bands are calibrated against the full 300-school cohort — a "Distinguished" mark is meaningfully harder to earn than a "Strong" one.

The same colour bands are used inside each school profile, on category chips, radar charts and the annual score-history line — so a colour glimpsed on the Rankings page always means the same thing everywhere else.
