Extensive research has identified many quality-related challenges in the K-12-practicum. However, no previous literature reviews have synthesised the challenges of the various activities involved in the practicum supervision process (planning, teaching and observation, preparations for supervision, supervision sessions and post-supervision reflection). This review identifies interrelated challenges for the experiential supervision process, such as limited student activity, and qualitative challenges of observation, feedback, reflection and collaboration. The review highlights the lack of research on certain components and the need for a more holistic research focus regarding the interrelationship of activities involved in the supervision process, specifically in terms of quality. © 2024 The Authors.
