ABSTRACT. This study outlines the professional development of teacher educators. More specially, teacher educators' descriptions and definitions of professional development and their participating professional development activities are examined. Further, to what extent teacher educators develop themselves in the professional sense, and supports and obstacles are explored. Within a case design, fourteen teacher educators were interviewed. Data were triangulated with annual performance reports. Findings point to high enthusiasm of participants in developing their knowledge, skills and attitudes in their profession despite some obstacles. However, their descriptions of professional development are not clear and confused with in-service training. The findings also highlight the discussion about who should support teacher educators' professional development.
