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.

School survey perspectives
Pupils, guardians and staff — same school, different answers
Survey results broken down by respondent group on a 0–10 scale. Groups can experience the same school very differently — notable gaps are highlighted below.
PupilsGuardians
Text summary of the chart:
- Pupils: Safety too few responses, Study environment too few responses, Stimulation too few responses, Support too few responses, Anti-bullying too few responses.
- Guardians: Safety too few responses, Study environment too few responses, Stimulation too few responses, Support too few responses.
Results with fewer than 5 responses are shown as “too few responses”.
Automatically flagged gaps
At least one respondent group has too few responses on the overlapping measures, so gaps cannot be calculated.
Staff results are not published per school by Skolinspektionen today, so the staff view appears only when available.
SALSA result
+9.0A statistical model that compares schools’ results with what is expected given the student composition.Read more in glossary →Performs as expectedThe residual is actual minus expected merit value; positive means the school lifts pupils more than the model predicts.
How should SALSA be read?
SALSA is a statistical comparison metric, not a school rating. Small cohorts and individual year groups can create uncertain signals, so read it together with pupil counts, survey data and other sources.
