In today's classrooms, textbooks play a very crucial role in the realm of language teaching and learning. And after teachers, they are considered to be the next important factor in the second/foreign language classroom. Therefore, selecting a proper textbook for a class has been one of the most important tasks for teachers. Whether the teacher should have the freedom to select the materials for evaluation and adaptation or not still remains controversial. One thing is clear, however and that is evaluation is usually done and no one denies its necessity. Along the lines of arguments presented so far, the main thrust of the present research is to carry out an evaluation on a series of ELT materials namely, Interchange 3rd edition. For this purpose Littlejohn's detailed framework (1998) is employed in this attempt. The scheme attempts to evaluate the selected textbook regardless of how it is used in the classroom, what he calls analyzing the material 'as it is'. Interchange is not completely along with the objectives intended for it. It doesn't use learners or even the teachers as a source for its content. Supra sentential level as well is ignored for both the expected output and input of the learners. More importantly these are not the learners who initiate the tasks. Interchange series; on the other, hand focus mainly on pair works and meaning. They also encourage students to use the language and more importantly they more often require them to express themselves than to be a listener.
