The purpose of this study was to shed light on how work-related teacher support in the form of special educational consultation can promote the professional development of teachers working in rural schools located in sparsely populated areas. The phenomenon studied was professional collaboration between class teachers and special educators in the context of special educational consultation. The empirical data were collected through interviews and observations in three rural schools in the northern part of Sweden. The findings indicate that special educational consultation is perceived as support and collaboration. The class teachers appreciate the support they receive from special educators. The collaboration is characterised by professional exchange and mutual problem solving. Distributed expertise seems to be a crucial element of the collaboration. The conclusion is that collaborative special educational consultation enables class teachers to support pupils with special educational needs and strengthens professional collaboration between class teachers and special educators.
