What Swedish schools can legally ask parents to pay
Compulsory education must be free, although limited one-off costs are permitted. A timely back-to-school guide draws the line for parents.

A back-to-school request can look small on its own: a bus ticket, an entrance fee or money for a class trip. The important question is whether a family is being invited to help or being made to pay for education that should be free.
The Swedish National Agency for Education says compulsory school must be free. Pupils must receive the books, learning tools and equipment needed for their education without charge, as well as nutritious school meals.
A school may occasionally allow an insignificant cost, such as public transport or museum admission. Even small sums can break the rule if they recur. Schools also cannot charge an application or queue fee.
For a school trip, parents may be asked for voluntary contributions on isolated occasions. Every pupil must still be able to join, and the payment cannot exceed the school's cost for that pupil.
The practical line is simple. A school can ask for truly voluntary help or an occasional trivial expense. It cannot make a child's access to ordinary teaching, essential materials or a shared activity depend on a parent's ability to pay. The school organiser is responsible for keeping education free.
