The purpose of this study was to examine the relationship between nursing work environment perception, career barriers and career identity of graduating grade nursing college students and factors affecting career identity. The data collection was conducted from June 3 to June 28, 2019 with 212 students in grade 4 of C University in S city. Career identity, $2.65{\pm}0.46$, $3.23{\pm}.57$, and $2.28{\pm}.77$, respectively. Career identity was positively correlated with nursing working environment(r=-.654, p<.001) and career barrier(r=.319, p<.001). The nursing work environment was negatively correlated with career barriers(r=-.216, p<.001). The variables that affect the sense of course are the career barrier(${\beta}=-.527$, p=.000), recognition of nursing work environment(${\beta}=.131$, p=.014), practice satisfaction(${\beta}=-.154$, p=.009), and this variable showed an explanatory power of 50.1% on career identity. Therefore, it is necessary to make efforts at the school to enhance awareness of nursing work environment and satisfaction in practice, improve clinical practice, and lower the career barrier through support and support from hospital and nursing managers.
