The purpose of this paper is to address changes in school placement and classroom participation with respect to children with disabilities of primary school age in Norway, as well as examining the factors which explain variation in school placement and classroom participation. School placement refers to whether children with disabilities attend regular school, while classroom participation refers to time spent in regular classrooms at regular schools. The analysis is based on longitudinal data drawn from surveys undertaken in 2003 and 2006, of parents of children with disabilities. Present findings suggest there are no major changes in school placement during primary school years, which is contrary to earlier findings. However, the amount of time children with disability are absent from regular classes does increase significantly as the children become older. Size of municipality population, type of disability and degree of impairment are the main factors which have an impact on school placement. In addition to these, the amount of special education also has an impact on classroom participation. There are small changes in mechanisms that lead children out of both regular schools and classrooms, during their primary school years. However, some of the identified factors strengthen in importance as the children become older. The apparent policy change for older children, from special school placement to an "out of class" practice, is discussed. It could be seen as regular schools' adaptation to the tension between the prevailing ideology of inclusion and schools' maintenance of existing practice. (Contains 6 tables and 1 note.)
