The study aimed at developing a hypothesized model and a validated questionnaire of language education glocalization (LEG) for the first time to accomplish systematic data generation and collection of the Iranian EFL teachers' perceptions regarding the LEG. In order to develop the model, extensive readings of the related literature were executed and expert consultation was conducted leading to formation of a hypothesized model. To test the model a questionnaire was developed and validated to tap the components of the model. Cronbach's Alpha coefficient was used to measure the reliability of the questionnaire estimating 0.96 for the whole questionnaire and exploratory factor analysis along with content analysis confirmed the validity of the questionnaire. After running exploratory factor analysis, to check whether the questionnaire data fits the hypothesized model of LEG introduced at the beginning of the study, a confirmatory factor analysis was done. Then, the final version of the questionnaire was administered to 270 language teachers to gather the data to feed it to the model to see the extent to which the model fit the data. The results of the study revealed that although the model has been the first one of its kind, it displayed a reasonable degree of reliability and validity.
