The upper secondary school had around 450 students last academic year. The decision means that they, a bit into the summer vacation, must get a place at some other upper secondary school.
"It is now important that each student contacts their home municipality or an independent upper secondary school as soon as possible to secure their continued education", writes the School Inspection in a press release.
The deficiencies at the school are, among other things, that the students have not received the teaching time they are entitled to, special support and grading.
The principal for the upper secondary school is AF Affärseffekt Framtidsskola AB, which with the decision is not allowed to conduct upper secondary education. The School Inspection's decision can, however, be appealed.
