The purpose of this study was to test and validate the Engaged Teacher Scale (ETS) in a Turkish context (ETS-TR). In order to test the construct validity of the ETS, data were collected from 388 teachers in two northeast cities of Turkey. First-order confirmatory factor analysis results supported the 16-item and four-factor model of ETS while second-order confirmatory factor analysis suggested that a single factor was also appropriate for representing teacher engagement. Additionally, four multiple linear regression analyses were conducted to provide further validation evidence. Results showed that subscales of the ETS-TR were found to be positively correlated with teacher self-efficacy. Given our evidence of validity and reliability, we recommend researchers interested in measuring the engagement of Turkish teachers to consider using the ETS-TR. The adaptation of ETS into Turkish also provides a measure for use when conducting research examining cultural comparisons between English-speaking and Turkish teachers.
