The performance appraisal (PA) system establishment in scientific research institutes on traditional Chi-nese medicine (TCM) plays an important role in the management of TCM research work, which can set up both well-defined guidance and favorable appraisal regimen for scientific researchers, so that leads to the accomplishment of the scientific objectives. However, current PA system establishment has fallen seriously behind the real demand in most TCM research institutes. As a result, there is a serious lack of a mature, efficient, standardized, propagable PA system in TCM research field. In this paper, we tried to discuss the current situation and key issues in building modern PA system in TCM research institutes. The PA system development in scientific research institutes on TCM was pointed out. The PA system should be based on existed referenced similar platforms, with full consideration on professional features and Chinese culture. The PA system establishment should be with most science, systematicness, objectivity, and guidance. The PA system should also be established to evaluate the scientific researchers equitably, guide the scientific trend, provide proper institute, and promote scientific research.
