The purpose of this study was to detect nursing professional self-concept, clinical practice satisfaction, clinical competence, career identity, to identify factors that affect career identity for nursing students who have experienced clinical practice until the first semester of the fourth grade, and to use it as basic data to develop nursing education programs that form the right career identity of nursing students. From June 15 to July 10, 2022, an online survey of 191 fourth-year nursing students at two universities in G City was conducted through a self-reported questionnaire to collect data. The data collected in this study were analyzed using the SPSS 19.0 program. As a result of this study, the average of career identity and nursing professional self-concept on a four-point scale were 2.52 points and 3.19 points, respectively, and the clinical performance ability and clinical practice satisfaction on a five-point scale were 4.0 and 3.81 points, respectively. The factors affecting the subject's career identity are professional self-concept (β=.34, p<.001), selection motives (β=.27, p<.001), major satisfaction (β=.22, p<.001), clinical practice satisfaction (β=.21, p<.001), and these variables showed 56% explanatory power for career identity. In conclusion, this study suggested that grade-specific major adaptation programs and theory and practice education-linked nursing education programs that can improve nursing professional self-concept, major and clinical practice satisfaction are needed to establish a career identity of nursing students. In addition, it is suggested that each university needs to strengthen career experience programs so that high school students can choose a nursing department in consideration of their correct understanding and aptitude for nursing major.
