To support the national and international aims of inclusion, "special teacher" training in Sweden was replaced in 1990 by "special educator" training. These special educators would supervise the teachers in their school and would not exclusively teach students. The aim of this study was to investigate what the principals of 14 municipal compulsory schools in Stockholm County thought about the organisation and realisation of special education in 1996 and 2006 respectively. According to the results, there were fewer segregated groups in these schools in 2006, but an increasing number of students were placed in segregated groups that were common to several schools or municipalities. Principals at schools with teaching teams usually saw the special educator as a coordinating and supervising resource while others preferred the special teacher function. The former approach led to a more inclusive school and the latter in the direction of exclusion.
