Aim: The educational approach towards practice placement education in health-related disciplines has changed in recent years. The use of collaborative or peer learning models has increased, associated with positive effects on desired outcomes such as learning, competence and reflective practice. At present, there is little published literature on the implementation or use of such models in dietetics practice placement education. The aim of this study was to conduct a pilot study of a collaborative peer learning 2 students to 1 educator (2:1 model). Methods: Experienced practice placement educators from four clinical sites in the discipline of dietetics in the Republic of Ireland were invited to participate in the study and form an advisory group. Feedback from this group was used to inform the design and development of a framework to guide the wider implementation of the 2:1 model. Results: Feedback from the pilot study was largely positive, with all four sites willing to facilitate a 2:1 model again. The main recommendation was that the practice placement educators require more practical information on the implementation of a 2:1 model, particularly the facilitation of the peer feedback process. In response to this feedback, the Lynam framework was designed, which is the focus of this paper. Conclusions: This pilot study of a 2:1 model in dietetics practice placement education informed the design and development of a framework for implementation of the model. Further research into the use of the 2:1 model for practice placement education and the effectiveness of the Lynam framework to guide the implementation of this model is required.
