This study explores the speech therapists' transfer of learning in boundary crossing from the university to the field, in order to understand how to support students in developing an epistemic agency. Our case concerns the qualitative analysis of student's assignments about academic knowledge and professional experiences in order to explore the change (in epistemic agency and boundary crossing) that takes place within the course. The results show the students' difficulties to link their former readings with their present observations; the impact of emotions; and the types of expertise they need in terms of educational/therapeutic activities
