Data coverageHigh4/5
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.
4 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.
