Scientific performance evaluation of college teachers has unique significance to the development of universities with high competitiveness. This paper builds different index systems for different types of disciplines and sets different index weights for different kinds of teachers in the corresponding index systems. Finally, it realizes the classification and type-discrimination based on the performance evaluation of college teachers. Based on the analysis, we take a middle university as an empirical research which confirms the feasibility and science of this kind of evaluation method, and give some opinions or suggestions which benefit the development of this university. It is hoped that this paper can shed some light on the research on the performance evaluation of college teachers.
