The current study aimed to develop and analyze a dementia care center nurse (DCCN) job description using Developing a Curriculum (DACUM) in Korea. Seven DCCN panels participated in the DACUM workshop to define the duties and tasks. The developed duties and tasks were validated with a survey that included the importance, difficulty, frequency, and educational needs of the duties and tasks. Descriptive statistics were used to analyze the data collected from August to September 2020. Nine duties and 111 tasks were identified, with "dementia screening" ranking the highest among the duties and "management of cognitive programs" ranking the lowest. The task with the highest rank based on the determinant coefficient and educational needs was "conducting the first stage of the diagnostic test," whereas the task with the lowest rank was "recording special issues." Findings can be used as fundamental data for designing educational programs aimed at enhancing the competencies of DCCNs and as a tool for evaluating their job performance.
