摘要：AbstractThe highest purpose of the present paper is to carry out an evaluation of the EFL course book “English Result” series in two levels of intermediate and upper-intermediate being currently trained in several language institutions in Iran. In order to accumulate data, Litz's questionnaires (2005) were conducted on the basis of the students’ and instructors’ responses to the subdivisions in the checklist. One hundred two EFL teachers and one hundred eighty students appraised the series. Cronbach's Alpha 0.875 and 0.884 were accompanied to estimate the reliability of the students and instructors questionnaire respectively. Regarding the accomplished results, the researcher specified that lack of TTC program; i- tools features, the clattered passages and pictures were the main week points of this series.
