Data coverageMedium2/5

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.

2 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.

What is the Skolkoll Score?

Kronan is a medium-sized municipal compulsory school with 150 pupils.
Kronan is a medium-sized municipal compulsory school with 150 pupils. The share of qualified teachers (84%) is above the national average of 72%.
