In recent years, media revelations about religious free schools have attracted a lot of attention and strong emotions.
In the past year alone, the School Inspectorate has closed 12 religious free schools.
All of them are Muslim schools that were closed for financial reasons or because Säpo sounded the alarm that students are at risk of radicalisation.

But the Commission's review can show that schools that engaged in so-called spiritual abuse have been able to continue for a long time.
For example, it is about teaching students that there are demons, that impure thoughts lead to hell and that homosexuality is a sin.
The concept of spiritual abuse is accepted in psychological research.
In various religious contexts it is used to understand the trauma it can mean for a child to be subjected to intimidation, guilt and manipulation by a person in a position of spiritual power.
- I believed in demons, I knew they existed.
I was afraid of them, which meant that I always slept with the lamp on at night, says Madde, who finished the ninth grade at Kristna skolan in Stockholm almost 15 years ago.
The Christian Free School Council: We are doing a good job
According to Swedish law, teaching in schools must not be characterized by religious elements and must rest on a scientific basis.
Religious elements may be present in school, but they must be voluntary and must not take place during class time.
Assignment review has gone through the School Inspectorate's reviews, compiled media revelations about misconduct - and interviewed several former students at religious free schools.
The testimonies of spiritual abuse stretch back 20 years to the present day.
The survey shows that no religious free school has so far been forced to close due to deficiencies related to spiritual abuse.
According to the interest organization Kristna friskolerådet, this is proof that the schools are doing a good job,

But many former students that Uppdrag gränskning spoke to say that it is only in adulthood that they understood what they had been through.
They also say that they have been told what to say if the School Inspectorate comes.
- We were not allowed to mention that the morning prayer was obligatory and we were not allowed to say that we laid hands on people to heal them from diseases.
It wasn't lying.
If you say something that is not true regarding this particular matter with the School Inspectorate, then it is not a lie, there it is not a sin.
That's when you stand up for this movement, says Stefan, a former student at Kristna skolan in Stockholm.
The School Inspectorate: We have the tools
The School Inspectorate believes that they have the tools they need to find spiritual elements in the teaching at religious free schools.
- I think it would be a skewed picture to say that we wouldn't be able to handle this at all.
But I'm not saying that we don't have challenges or that there are several complex issues that can be tricky for inspectors, says Helén Ängmo, director general at the School Inspectorate.

Psychotherapist Helena Löfgren says that she is very badly affected by the children's suffering and the authorities' ignorance and naivety.
According to Löfgren, the students' descriptions are clear examples of spiritual, psychological abuse.
- To understand the children, try to remove the word God: "Me and my boss have you under constant surveillance.
We know everything you do, think and feel.
If you disobey my rules, or even think a wrong thought, at any moment he will subject you to never-ending torture”.
Kristna skolan i Stockholm writes to Uppdrag gränskning that they as a school want to try to absorb both positive and negative reviews, but decline to participate in Uppdrag gränskning.
