A composite of five open data sources — a starting point, not a grade.
The score reflects results directly. Given the pupil intake, the school still performs in line with expectations — see value-added.
Data coverageMedium3/5
Why this score?
Skolkoll score is Skolkoll's composite indicator based on available data sources. It is not an official quality measure and should be read together with the underlying data.
3 of 5 score dimensions have school-specific data.
When school-specific data is missing for a dimension, the neutral value 50 is used. That does not automatically lower the school, but it makes the score less informative.
Results in line with the pupil intakeA statistical model that compares schools’ results with what is expected given the student composition.Read more in glossary →What is value-added?The school's own contribution given its pupil intake (Skolverket's SALSA model) — not a quality guarantee, and not comparable between years.
