Research in inclusive education lacks studies in examining how teachers experience their work. The aim of the study was to contribute knowledge regarding teachers’ own perspective on the work with additional adaptations and the prerequisites to meet students’ different needs from classes year 7-9. The data collection method was semi structured interviews and nine interviews were conducted with teachers. The interviews were transcribed in full and empirical evidence condensed by qualitative content analysis. The result showed that teachers describe their work based on different themes; complexity, tacit knowledge and relational skills. The result also showed that the prerequisites that teachers receive in their work with additional adaptations are different types of support structures and that the organization around this work is different in different schools. We found that categorical, relational and the dilemma perspective were represented in teachers descriptions of their work with additional adaptations and that none of the perspectives dominated the empirical evidence. In organization with clear structure and procedures, principal prioritises collegial learning, competence development and support as conditions for the work the relational perspective dominated. Conversely, in organisation lacking support from principal and student health and teachers lack of knowledge in their work with additional adaptions, the categorical perspective dominated.
