This study examined the collaborative practices between teachers and speech and language therapists (SLTs) within an inclusive setting, interviewing 17 professionals' couples. Three distinct phases of collaboration were identified: planning (e.g. reviewing student performance), co-teaching in the classroom, and evaluation (reflecting upon joint activities). Conditions fostering collaboration were categorized into individual (interpersonal relationships), school-based (directive management) and policy (current regulations) dimensions. Findings suggest that the extent of collaboration varies and is influenced by interconnected conditions. This research enriches the literature by offering a classification of collaborative work between teachers and SLTs and underscores the conditions impacting it, and is invaluable for stakeholders aiming to advance inclusive educational settings.
