Children are increasingly diagnosed with neuropsychiatric disorders which is an expression of the contemporary increase in the medicalization of deviance. In several countries there have been fierce debates about the pros and cons of diagnosing children. Yet little is known about the teaching of these pupils. The purposes of the presented studies were to provide an overall picture of the education of children with AD/HD in the Swedish comprehensive school and to more closely analyze educational arrangements designed in order to meet the needs of these children. Two studies were made. Firstly, a questionnaire was sent to all Swedish municipalities regarding their education of children diagnosed with AD/DH. Several measures were taken in order to secure valid and reliable data and to achieve a high response rate (76 %). Secondly, case studies were made in 5 municipalities with groups especially designed for children with AD/HD and 5 municipalities without. Data from both studies will be presented. However, the focus will be on educational arrangements and teaching strategies in the groups specifically designed for children with AD/HD in comparison with school situations for pupils with AD/HD in municipalities without such groups.
