In this study, the direct and indirect relations between school culture and the organisational commitment of primary school teachers were analyzed. The subjects of the research consisted of primary school teachers who worked at a district in Istanbul in the academic year 2007-2008. The sampling group was defined by the cluster sampling method. In total 200 teachers participated. Two scales were used to collect data, the organisational commitment scale (OCS) and the school culture scale (SCS). Linear regression and path analysis were used to explain the influence of school culture on organisational commitment, and LISREL 7 was used as a structural equation model. The findings indicated that although there was a positive correlation between school culture and organisational commitment, the direct effect of school culture on organisational commitment was not meaningful.
