How we ranked schools
Schools are sorted by Skolkoll score, the same 0-100 composite quality measure shown on individual school pages. The canonical calculation combines results, staff, added value, pupil safety and resources. Missing school-specific dimensions use the neutral value 50 so absence of data does not by itself lower a school.
