How we ranked

The list contains compulsory schools in Södertälje that offer Years 7–9 (both F-9/1-9 units and stand-alone lower-secondary schools) and have published a Year 9 final-grade score. Schools are sorted on the Skolkoll score, the same 0–100 measure shown on school pages — it combines results, staffing, value-added, safety and resources. Where a dimension lacks school-specific data the neutral value 50 is used. The SALSA deviation is also shown separately as context. For compulsory schools, the SALSA residual is part of the value-added score dimension when available, but it is not a standalone quality grade.The Year 9 score, teacher certification and pupil counts are shown so you can read the ranking in context.

Note: "Best" here is a data-driven comparison based on public statistics — not necessarily the best school for your child. Location, pedagogical profile, well-being and pupil composition also matter. Read the full methodology →
