Purpose: To examine school nurses' perception of job performance difficulties, stress, identity, and satisfaction, and to identify the factors that affect job satisfaction. Methods: Data were collected through online survey questionnaires distributed to 189 regular school nurses working in Metropolitan I. The self-report questionnaire consisted of three instruments and demographic questions. The data were collected from June 29 to July 31, 2020, and analyzed using frequency, percentage, mean and standard deviation, t-test, ANOVA, Pearson's correlation coefficient, and multiple regression statistical techniques. Results: Perception of job performance difficulties showed a significant positive correlation with job stress (r=.20. p=.007), job identity (r=-.55, p<.001) and job satisfaction (r=-.39, p<.001), and each showed a negative correlation. Job stress showed a negative correlation with job satisfaction (r=-.65, p<.001), and job satisfaction and job identity showed a positive correlation (r=.53, p<.001). Job stress (β=-.58, p<.001), job identity (β=.43, p<.001), school-level elementary school (β=.19, p<.001), and middle school (β=.13, p=.011) were found to have a significant effect on job satisfaction. Conclusion: As job stress, job identity, and school level are important factors influencing job satisfaction, interventions are needed to lower the job stress of school nurses and strengthen their job identity. In addition, since the job satisfaction of school nurses can have a great impact on the health and happiness of students as well as the quality of life of future generations, it is necessary to improve policies and systems to increase the job satisfaction of school nurses.
