In this research, it was aimed to determine the level of teachers' proactive personality traits predicting the problemsolving skills consisting of the sub-dimensions of confidence in problem-solving ability, personal control and approach-avoidance. The relational screening model was used in this research which was prepared in accordance with the quantitative research paradigm. Accordingly, the concept of proactive personality was discussed as an independent variable, and problem solving skills were discussed as dependent variables. It is seen that there is a positive and significant relationship between teachers' proactive personality traits and problem solving skills and confidence in problem-solving ability, approach-avoidance and personal control, which are the sub-dimensions of problem solving. Based on the ANOVA values are examined for all three sub-dimensions, it could be said that the value p is significant, in other words, the regression model is valid. According to the t-test results regarding the significance of the regression coefficients, it is seen that proactive personality traits are a significant predictor on the sub-dimensions of confidence in problem solving ability, approach-avoidance and personal control. Furthermore, according to Durbin-Watson values for all sub-dimensions, the assumption that there is no relationship between error terms is confirmed.
