Competency-based medical education (CBME) has become a trend in global medical education. Entrustable professional activities (EPAs) are one of the means to implement CBME. To provide up-to-date teacher training for implementing radiographers’ CBME, the Taiwan Association of Medical Radiation Technologists has organized a Three-Stage Radiographer CBME program. The three stages are as follows: (1) Competency development: establishing EPAs for radiographers. (2) Competency-oriented teaching and learning experience: promoting CBME teacher training. (3) Planned and systematic competency development and assessment: promoting and implementing the CBME teacher training program nationwide. Through the promotion of CBME, teaching based on direct EPA observations, as well as the establishment of a competency development framework and a systematic assessment model for in-service radiographers, the Association expects to improve the competency development of and education quality for radiographers in Taiwan.
