The aim of this study was to investigate the longitudinal development of students having difficulties with reading and their decoding ability in Swedish compulsory school. Another aim was to relate this to the experiences of educational activities expressed by students and parents. The decoding ability was assessed by a word chain test given at three occasions and was compared with results on a letter chain test. Retrospective interviews were performed with students and parents. The decoding ability tended to improve for most of the students over time, although some of them failed to improve or even decreased their scores, indicating a lack of environmental adjustment. Special educational support was according to students and parents organised in small and often very heterogeneous groups where the students sometimes received adequate support but often felt deviant from friends in their regular classes. The responsibility for helping the children with their schoolwork was allocated to the parents. Research in this area demonstrates the necessity of a well-structured and stimulating learning situation. Yet, the development of these students' decoding abilities, personal experiences, and parental involvement indicate that competence and resources at school regarding children at risk for developing reading difficulties are often lacking in the Swedish educational system.
