How we rank

Our composite weights eight categories. Each is scored 0–100 by our editorial panel and audited against 30 sub-criteria drawn from school records, university placement audits, alumni surveys, campus visits and parent interviews. Schools cannot pay for placement or preview scores.

Score key

Reading the scores

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.

    90–100

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.
