Decisions related to textbook selection and evaluation are of great importance. The purpose of this study is to evaluate the three English language textbooks currently used at high schools in Iran from the high school English teachers' point of view.For this purpose, a 46-item questionnaire was developed about the five sections of the textbooks (vocabulary, reading, grammar, language functions, and pronunciation practice), their physical make-up, and practical concerns. Fifty highs school teachers with more than five years of teaching experience were asked to reflect on the questions by checking one of the four options included.The results indicated that the textbooks are not acceptable from the teachers' point of view considering their five sections, their physical make-up, and some practical concerns.
