The Party building of high school teachers plays an important role in promoting the professional development of teachers and improving the level of school education and teaching. It helps to clarify the direction of teaching，contribute positive energy to the moral education and provide positive impetus for the daily work of teachers. In order to play the role of party building in promoting the professional development of high school teachers，we should strengthen theoretical learning to enhance teachers’ learning and innovation ability，deepen the practice process to cultivate teachers’ responsibility ability and standardize the system construction to strengthen teachers’ organizational and disciplinary ability. Based on the above measures，the High School Affiliated to UIBE has made solid progress in Party building and achieved outstanding results in teacher professional development. At present，we should pay attention to three combinations in promoting the Party building work in senior high schools：the combination of Party building work and moral education，the combination of theoretical education，practice cultivation and system norms，and the combination of the Party building work and the needs of Party members.
