The purpose of this study is to determine the effect of gender, marital status, subject matter, school type, educational status and seniority variables on teacher burnout. In this regard, a meta-analysis was conducted for the studies on teacher burnout in Turkey. The effect size analyses were performed with 100 studies for gender, 73 for marital status, 17 for subject matter, 15 for school type, 34 for educational status, and 54 for seniority variables. In the study, the possibility of a publication bias was examined. The results of the study conducted with a random effects model revealed that gender, marital status, subject matter, and educational status had a very low effect on teacher burnout, whereas this effect was very low or low for seniority, and low or medium for school type variables. Besides, the variance among the studies for study-type, grade-level, and region moderators did not differ significantly apart from gender variable.
