The consequences of organisational commitment (OC) are of great importance to organisations. Considering the effect of teacher commitment on student success and the increasing teacher turnover rates in the world, studies focusing on the organisational commitment of teachers gained more importance. However there is still a significant gap about the demographic and other factors that affect teachers' organisational commitment. This meta-analysis examines the relation between gender and organisational commitment of teachers. The relation was investigated as overall and in sub-dimensions of organisational commitment: affective, continuance and normative organisational commitment. 33 studies that use the Allen Meyer Organisational Commitment scale and which were carried out between 2000-2014 were used in the study. The sample included 11,690 teachers (female 6,232, male 5,458). Although the mean effect sizes for overall, affective, continuance and normative OC show that the effect of gender on the organisational commitment of teachers is in favour of females, the results highlight that gender is not a significant variable in determining teachers' level of organisational commitment.
