Objectives: The purpose of this study was to examine of practice transition shock, resilience, and professional self-concept of nursing students and factors affecting career identity. Methods: The subjects of this study were 142 nursing students attending two universities in G city. Data collection was conducted from September 15 to September 30, 2023. Data were analyzed using independent t-test, ANOVA, Pearson’s correlation and multiple regression analysis with SPSS 27.0 program. Results: Career identity was significantly positively correlated with resilience (r=0.79, p<0.001) and professional self-concept (r=0.85, p<0.001), and significantly inversely correlated with practice transition shock (r=-0.86, p<0.001). Factor affecting career identity for nursing students were practice transition shock (β=-0.45, p<0.001), major satisfaction level (β=0.23, p=0.001), resilience (β=0.14, p=0.039). It showed an explanatory power of 83.1%. Conclusions: The results of this study show the development of programs of major satisfaction, mitigate practice transition shock, and enhance resilience were required to improve career identity among nursing students.
