The collected data were analyzed with descriptive statistics, t-test, ANOVA, Scheffé test, Pearson’s correlation and stepwise multiple regression analysis using SPSS 25.0. @*Results@#Clinical performance showed a statistical difference depending on the number of education session for competency, and it showed a positive correlation with professional autonomy and teamwork. The factors affecting the clinical performance of the tertiary hospital nurses included in teamwork (β=.40, p<.001), professional autonomy (β=.27, p<.001). These factors accounted for 31% of clinical performance (p<.001). @*Conclusion@#It is important to find ways to improve clinical performance of tertiary hospital nurses. Furthermore, there is a need to include continuous and systemic education programs for professional autonomy and suitable programs to elevate teamwork.
