Frontier ethnic regions are endowed with unique traditional Chinese medicine(TCM) resources, while specialized talent reserve serves as a core element to activate industrial development and inherit ethnic medical culture. This study addresses the regional needs for TCM talent cultivation by constructing a "2 + N" student value-added evaluation model with multi-stakeholder participation based on a multiple linear regression model. By establishing dynamic individual growth profiles, tracking students‘ developmental trajectories in dimensions such as professional competence and comprehensive quality, and implementing personalized cultivation guidance, the research aims to activate students‘ intrinsic motivation for self-development, achieving the integration of all-round development and professional capability enhancement. The "2 + N" evaluation model, which distills the collaborative mechanism of multi-stakeholder education, provides a new framework for improving the theoretical system of TCM talent cultivation evaluation and offers a practical paradigm for characteristic talent training in ethnic regions. This exploration holds significant theoretical and practical significance for enhancing TCM talent cultivation quality and promoting the sustainable development of TCM undertakings in frontier ethnic regions.
