This research examines the impact of teachers' positive psychological capital (PPC) on their job satisfaction (JS) levels. In the study, the relational survey model was used by conducting hierarchical regression analysis. The sample of the study consists of randomly selected 376 teachers in Batman, Turkey. The data were collected with the "Positive Psychological Capital Scale" and "Minnesota Job Satisfaction Scale (MSQ-Short form)". According to the results, the PPC levels (total scores and dimensions) of the teachers are at a very high level; only the optimism dimension of the PPC scale and JS were found to be at a high level. In the regression analysis, the model (Model 6) that measures the effect of all dimensions of PPC on JS is significant. This finding implies that PPC is a significant predictor on JS and approximately 22% of the total variance in job satisfaction is explained PPC. The results of the study imply that self-efficacy and optimism components of PPC can be used to increase JS of teachers even the economic needs are not adequately met.
