The aim of this study is to evaluate “English for Palestine IV”. To achieve this aim, the researcher used several evaluative criteria such as: a questionnaire that contains important items through which a person can judge the suitability of a good TEFL or ESL textbook. Additionally, the researcher used the characteristics of a good textbook in order to see whether the textbooks mentioned above are suitable or not. The characteristics of a good textbook and the questionnaire are adopted from Solicits, (1978); Al- Makhzoumi (1992) and Macmillan (1997). The questionnaire was given to 60 of the English teachers who teach the fourth graders from Jenin and Qabatia districts. After the thorough observation and analysis of the textbooks regarding the different evaluative measures, the researcher noticed that these textbooks are suitable and he strongly recommended using these textbooks in private as well as in government schools after carrying out the suggested modifications mentioned in the researcher’s suggestions and recommendations.
