The main objective of this paper is to present a ranking model for social security healthcare centers using a multi-level performance evaluation. This applied research has a mixed approach. The data collection tools are library studies and questionnaires, and the data were analysed using a one-sample t-test and exploratory factor analysis. The multi-level performance evaluation model for social security hospitals was reviewed through a questionnaire survey, and the themes of individual, group, and organizational levels were identified, which examine various aspects of individual and organizational performance. Simultaneous attention to the performance of employees, organizational units, and the entire organization in the performance evaluation of healthcare centers can lead to a more comprehensive understanding. It can help rank and improve the effectiveness of performance improvement programs. The findings of this research can be used as a model for other healthcare centers. https://ijnaa.semnan.ac.ir/article_10332_b974006f61bd5a3f95e3e9530a579d14.pdf
