The major purpose of the present study was to construct an English Language Teacher Creativity Scale (ELT-CS). To this end, the questionnaire was designed by picking up the most influential factors of creativity. A total of 24 EFL teachers were rated by their 343 EFL learners on the ELT-CS. The WINSTEPS program was used to perform the Rasch measurement. Due to the fact that the data did not satisfy the criteria for adequate fit to the model, unidimensionality principle was rejected. As a result, consecutive approach was adopted to examine each subscale separately. Individual subscales functioned well and Rasch model held within subscales after removing items 12 and 39. Moreover, since the 5-category rating scale did not operate sufficiently, it was altered to 3-category rating scale. Finally, statistical results were discussed, and implications were provided in the context of English language teaching.
