ABSTRACT
The purpose of this study is to develop a reliable and valid scale that measures teachers’ commitment. Thesample of the study consists of two separate teacher groups. The first group consists of 310 voluntaryteachers working in primary and secondary schools in Malatya province. The second group consists of 201teachers working in 20 different schools. In order to test the construct validity of the scale, the data obtainedfrom the first group were subjected first to exploratory factor analysis and later to confirmatory factoranalysis. In order to test the criterion validity of the scale Minnesota Satisfaction Questionnaire (MSQ) andMaslach Burnout Inventory (MBI) were administered on a second group of teachers. For reliability studies,internal consistency coefficient and test-retest correlation coefficient were estimated using the relevantsoftware. Findings obtained from exploratory factor analysis and confirmatory factor analysis showed thescale has one factor structure with 17 items. Results revealed that Teachers’ Organizational CommitmentScale (TOCS) has a high positive correlation with MSQ and average negative correlation with MBI. Theinternal consistency of the scale was found “.96”, and test-retest correlation coefficient was found “.88”.These results show that TOCS is a valid and reliable scale to measure teachers’ commitment.
