摘要：An increased enthusiasm on teacher accountability, in recent times, has led policymakers and teachers to a significant care over evaluating teachers’ success. To thisaim, a 40-item Teacher Success questionnaire was developed and validated by theapplication of the Rasch model. The Rasch model is used to decide whether thescores of an instrument are meaningful, significant, and purposive. The test wasdeveloped in Persian to be used for Iranian teachers. The Rasch rating scale modelfor polytomous data was used to examine the psychometric qualities of the scale interms of dimensionality, use of response category, sample appropriateness, andreliability. The test was administrated to 828 Iranian EFL students. The resultsrevealed that the Rasch model fits the test after deleting 8 items from the scale.Moreover, it is confirmed that the scale enjoyed suitable reliability. This proposesthat the questionnaire is potentially valid and can be used as a measure of teachers’success in the Persian language settings.
