Therefore, the competencies of its employees must be improved to make it possible for them to have their best performances. In this regard, the present study aimed to investigate and identify the factors that affect the development of key human resource competencies in the Iranian Red Crescent Society and design an appropriate model for its evaluation. METHODS: The present applied qualitative research used an exploratory approach. The statistical population of this study consisted of managers and experts in the field of human resources of the Red Crescent Society who were selected using the snowball sampling method. Moreover, the required data were collected through semi-structured in-depth interviews and we reached saturation after 26 interviews. The collected data were analyzed using the Straussian version of grounded theory. Finally, the collected data were analyzed in the MAXQDA software (version 10). In total, 72 concepts, 568 sub-concepts, and 19 categories were identified in this research. FINDINGS: Five out of the seven fundamental principles of the Red Crescent Society and the International Committee of the Red Cross, including the principle of humanity, voluntary service, neutrality, impartiality, and independence are among the foundational factors and necessities of the development of human resources competencies and were axially coded in causal conditions. Improvement and development of individual, organizational, social, and professional competencies were the four main categories of this research that were selected as the main strategies for the development of human resource competencies. CONCLUSION: According to the results of data analysis, employing appropriate strategies for the evaluation and development of key human resources competencies can have beneficial consequences. More specifically, these categories include human resource efficiency, provision of desirable social services, enhancement of the community health, improvement of human values, increase of public trust and participation, and improvement of the financial position of the organization.
