Objective To establish an evaluation model for the competency of clinical teachers based on the McClelland competency model. Methods Core elements of the competency of clinical teachers were investigated by literature reviews, expert interviews, behavioral event interview (BEI), and questionnaires. The questionnaire of the competency of clinical teachers was prepared and the data relevant to characteristic items of the competency were obtained. The investigation data were proceeded by the exploratory factor analysis and confirmatory factor analysis. Results A distribution and classification model for characteristic items of the competency of clinical teachers was established, which included 6 class I factors and 20 class II factors. The efficiency and stability were proved by the confirmatory factor analysis. The classification of class III evaluation was performed for each class II factor. Conclusion This paper establishes a proven evaluation model for the competency of clinical teachers. The model is based on the solid theory basis. It has a comprehensive indicator system for factors and clear description for classes. The model is helpful for improving the scientificity of evaluating clinical teachers, teaching ability, and teaching quality.
