Teacher competency has always been a comprehensive ability closely linked to educational outcomes in schools. The formulation of the Southeast Asia Teachers Competency Framework (SEA-TCF) questionnaire provides quantifiable indicators for improving the overall performance of teachers in Southeast Asia. Given that the validity of questionnaires in different contexts may not always be consistent, this study examined the reliability and construct validity of the Thai version of the Southeast Asia Teacher Competency Framework (T-SEA-TCF) using SPSS, Amos, as well as Excel software. The research results showed that it has excellent internal consistency. Besides, its construct validity including factor loadings, convergent validity, and discriminant validity was tested by confirmatory factor analysis (CFA), indicating that the T-SEA-TCF was equally valid in the Thai context. A larger sample size and modifications to some of the items would contribute to a more effective T-SEA-TCF.
