Studying and reviewing textbooks can be considered essential steps in any curriculum. Therefore, the present nationwide study evaluated the strengths and weaknesses of the book "English for 10th Degree of High School Students". So, 400 students and 40 teachers of the 10th degree from Hamedan, Mashhad, Rasht, and Ahvaz participated in this research by completing the questionnaire developed by Abdolvahab (2013). In order to confirm the validity and reliability of the research instrument, first, the mentioned questionnaire in the scale of 100 students and 30 teachers was tested so that the reliability or Cronbach's alpha was equal to 0.86, and its validity was proved by Factor Analysis. According to the results, teachers found the book appropriate regarding the themes and content; however, they regarded the appearance and the sociocultural aspects of the book weak. The students believed that the book is suitable in terms of its content, themes, and appearance. But, they believed the book is to some extent weak considering the listening skill and the sociocultural aspects. It can be concluded that, generally, the book is successful based on the appearance and application, in achieving its goals, content, and language skills, and it has attracted the attention of both teachers and students respectively.
