The research instrument in the quantitative phase was a researcher-made. Findings: The face and content validity of the questionnaire was confirmed by experts in the field of education. Confirmatory factor analysis, convergent validity, and divergent validity were used to evaluate the construct validity, and hybrid reliability was used to evaluate the construct reliability. As well as, in the quantitative phase of research, structural equations under Smart PLS software were used to evaluate the standard model of teachers' professional competence. All factor loadings were significant at 99% confidence level in developing the standard model of teachers' professional competence on the basis of high-level documents of Education.
