This study examined the predictive relationships between collective teacher efficacy, job satisfaction, and burnout. In addition, the mediating role of job satisfaction in the relationship between collective teacher efficacy and burnout was tested. Three hundred fifty teachers participated in the research in which the correlational research design was used. Collective Teacher Efficacy Scale, Short Form Minnesota Satisfaction Questionnaire, and Maslach Burnout Inventory were used as data collection tools. Pearson Correlation Coefficients were calculated to examine the relationships between collective teacher efficacy, job satisfaction, and burnout. Structural equation model analysis was applied to test the mediating role of job satisfaction in the relationship between collective efficacy and burnout. The results indicated that collective teacher efficacy predicts job satisfaction positively and burnout negatively. Collective teacher efficacy and job satisfaction have a large effect on burnout. Evidence has been obtained that teachers' job satisfaction can increase and, accordingly, burnout can be prevented when collective teacher efficacy is achieved.
