Abstract: Objective Based on the current situation of Beijing "3+2" assistant general practitioner training in Beijing distributed in 10 teaching hospitals in the suburbs, we discuss how to improve the teaching level between different teaching hospitals, in order to achieve the homogenization of teaching effects. Methods From 2013 to 2018,the clinical comprehensive course joint teaching and research section conducted a test paper analysis of the completion test papers of the "3+2" assistant general practitioner "Clinical Comprehensive Course" trained in 10 teaching hospitals in the suburbs and searched according to the results of the test paper analysis. The difference points of teaching effects, and took measures such as organizing collective preparation for common corrections, establishing and enriching test questions, compiling "exercise set", and revising teaching courseware, were analyzed and evaluated. At the same time, in 2015, the relevant teachers were compiled and confirmed by the group discussion, and the "Key Points of Teaching Key Points" was published as the teacher's teaching support manual. The manual was implemented in the 2016 teaching process, with the aim of making different teaching units. In the teacher's teaching process, while exerting personal subjective initiative, uniformly teach the key teaching content, pay attention to the difficulty of the course, and jointly evaluate the teaching implementation effect. Results The difference in teaching effect between the 10 teaching hospitals was reduced from 40% in 2013-2015 to 17%-18% in 2017-2018 by compiling and using the key points of the course teaching. Conclusion Compiling and using the key points of teaching points has effectively promoted the overall improvement of teaching level of 10 teaching hospitals. At the same time, it can serve as a reference for teaching reference, focus on reviewing and reviewing students, correcting teaching deviations, and as a basis for assessing and understanding the knowledge of students. In order to further improve the teaching level and give full play to the effective role of key points in teaching, the key points of teaching points also need to be refined and sublimated through use and argumentation.
