PURPOSE: This study was done to analyze the job of clinical research coordinators (CRCs). METHODS: Through the "developing a curriculum (DACUM)" workshop, the definition of CRCs' role was described and CRCs' duties and tasks were identified. Finally, the developed duties and tasks were validated for importance, difficulty, and frequency. RESULTS: A CRC is defined as the one who coordinates and performs tasks related to clinical research/trials among investigators, participants, and sponsors according to the Good Clinical Practice at institutions conducting clinical trials. Twelve duties and 78 tasks were identified on the DACUM chart which represented the importance, difficulty, and frequency of tasks represented as A, B, and C respectively. Based on determinant coefficient (DC) of the task, the highest ranked task was confirming the eligibility of participants for research (DC=8.03) and the lowest was inventory management for clinical study materials (3.95). CONCLUSION: In this study, the job of a CRC was analyzed through the DACUM process and it was found that CRCs were doing various duties and tasks. Based on these results, it is suggested that it is necessary to develop CRC education programs considering the career ladder of CRCs.
