In this article focus is directed towards Study Guidance in the Mother Tongue (SGMT) and SGMT tutors’ professional roles in Swedish compulsory school. The aim is to study how SGMT tutors are positioned and position themselves in relation to official documents and other actors in school. Questions that are highlighted in the article deal with forms for participation in school activities, opportunities to agency and voice as well as expressions of professionality in the SGMT tutor role. The empirical material builds mainly on interviews with SGMT tutors together with official documents. The results show that there is big variation between individual SGMT tutors when it comes to their possibilities for agency and to make their voices heard, as well as when it comes to participation and influence. Several co-operating factors have been identified that may strengthen the SGMT tutors’ profession where competence and possibilities for co-operation with class and subject teachers appear as crucial. Also questions of organisational art, such as time allocated for preparation, are important for SGMT tutors’ profession.
