Educational lessons based on the conversational material Toolkit "Children - what does it involve?", will be delivered in the classroom at school and caring for the RCB simulator during three days and nights.

Education as usual.

Thirteen educational lessons based on the conversational material Toolkit will be delivered in the classroom at school, two lessons per theme. The themes consists of: 1) a card game: "What i wish" 2) Time 3) Money 4) Skills 5) Relations 6) Housing. The material is prepared and same for all schools. This intervention will be given 1-2 lessons per week over a period of 8-14 weeks. During this period the students also care for the RCB simulator during three days and nights, but with a break for "day care" for the simulator which was between 7 am and 5 pm when the students were in school. All students will practice handling the simulator to be familiar with all types of needs: to rock, change diaper, feed and burp and were taught the skills of head support, techniques to avoid rough handling.

The original ISA consists of 38 items of which most are statements with four response alternatives ranging from strongly agree to strongly disagree. It was translated to Swedish and to the cognitive level of students with intellectual disability. Statements were changed into questions and one response alternative "I do not know" was added. The items related to sexual activity and to contraception were omitted since it was not the focus of the intervention and also to ease the all over burden of lengthy questionnaires for the students.

The S-GSE contains 10 items and it has already been used in Sweden. The investigators adapted two of the items and added the response alternative "I do not know". The layout of the response alternatives was adapted to individuals with cognitive disability and the students were given the opportunity to use pictures or sign language for ease of understanding.
