Abstract: Nursing interns who were educated in nursing college for 2 to 4 years will take the clinical position after the internship stage. Knowledge, techniques and competences obtained in school need to apply into the practice, and competency-based education provided us an idea for interns' training in emergency department. Based on literature review and group discussion, the article described our competency-based training model from three aspects, the competence orientation, training model design and supervision and reflection. According to this model, the clinical teachers have the evidence to teach the students and the students have the contents to learn. As a result, the interns improved their clinical practice ability, involved in the clinical work by stimulating their own competences, promoted their competency development, and the realized the improvment of teaching and learning.
