Nordic International School Trollhättan
Part of group: Watma Group AB
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.
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.

Certified teachers and SALSA score need extra caution
This applies only to the values listed here.
This value is missing in full or in part.
This affects
- Certified teachers
- SALSA score
- This staffing metric is affected by FTE definitions, local reporting practices, and temporary vacancies. For preschools without a compulsory or upper-secondary school, the same field instead holds the share of staff with pedagogical higher education (see the measure Share with pedagogical higher education).
- SALSA is model-based and becomes less stable for small pupil groups or schools with rapidly changing pupil composition.
Other values here do not have this specific note.

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.
Text summary of the chart:
- Pupils: Safety 7.7, Study environment 4.9, Stimulation 5.6, Support 6.2, Anti-bullying 5.4.
- Guardians: Safety 7.6, Study environment 5.9, Stimulation 6.6, Support 6.4.
Automatically flagged gaps
Pupils report lower study environment (4.9) than Guardians (5.9). (on the 0–10 scale)
Pupils often perceive the study environment as worse than guardians do — they spend the whole day in the classroom.
Pupils report lower stimulation (5.6) than Guardians (6.6). (on the 0–10 scale)
Staff results are not published per school by Skolinspektionen today, so the staff view appears only when available.
SALSA result
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.
