The use of corpus linguistics in ELT is a modern method of developing the teaching the researcher has made use of the Corpus-based, genre-analytic approach to design an English text book for the first year of medical laboratory sciences students (MLS). The content teachers of the medical laboratory sciences have provided the designer with a large collection of medical terms and texts and the designers drew language and academic skills around those corpora. The designer has followed the basic criteria of syllabus design and materials development to design this text book. A text book evaluation check list is designed for the English language teachers who had taught the book to evaluate it and find out whether corpus based approach through which the book is designed help to develop it as considerable English text book that can be easily assigned to be taught for the medical lab students in the whole Sudanese universities. The results reveal that the textbook has helped the students to enhance their language competence as well as critical thinking. It also paves the way for the English language teachers to make use of the corpus based approach to develop the materials they teach for their ESP classes.
