Purpose: This study purposed to develop a model of self-regulatory body in nursing (SRBN), which is efficient under the current situation of Korea. Method: The study was conducted in three stages: 1) Analysis of the functions and roles of domestic institutes related to SRBN in their activities 2) literature review and case studies of overseas SRBN; and 3) development of the proposal. Result: Mostly, in foreign countries, SRBN performs the functions of improving the quality of nursing through education, standardization, regulations, researches and activities toward the government and, consequently, enhances the reliability and quality of healthcare services. As a measure against the opening of the domestic medical market to the world in the future, this study proposed a model of SRBN in order to be equipped with functions to protect people and qualities to compete with healthcare services in advanced countries. Conclusion: This study explains the significance of SRBN to nurses and policy makers who do not recognize the necessity of a SRBN, and its results may be utilized as reference materials for the Korean Accreditation Board of Nursing, which is currently playing the role of a SRBN, to perform activities toward the government for expanding, improving and maintaining its roles.
