A total of 1054 primary, secondary, and high school teachers at three different stages were included in the study. In the final stage of the process, the confirmatory factor analysis data were collected through the online administration. The findings of the research have indicated that Teacher Professional Motivation Scale consists of four sub-dimensions as inschool factors, out-of-school factors, professional development and respectability, and physical facilities. The results of the confirmatory factor analysis revealed that the four-factor structure of the scale showed acceptable agreement. The factor structure of the paper-pencil administration was also confirmed by the online administration. The internal reliability coefficients of the sub-scales are above acceptable limits for both for paper-pencil administration and online administration. As a result, the study shows strong evidence that both the paper-pencil form and the online form of the scale are a valid and reliable assessment tool that can be used to evaluate teacher motivation in schools.eninfo:eu-repo/semantics/openAccessteacher motivation; scale development; online administration; paper-pencil administrationArticle5147949810.9779/pauefd.707619501601WOS:000609186300019N/A
