The selection of the best appropriate textbook to a particular context requires a careful evaluation to ensure whether it is suitable to learners and match the teaching and learning purpose. The study was predominantly conducted to identify the strengths and weaknesses of New English Grade 10 after two years of pilot implementation at An Phuoc high school, Vietnam under six EFL teachers’ appraisal. The data were collected via a semi-structured interview with total 40 questions covering different criteria such as aims, attractiveness, language and topics, language skills and language areas, and methodology. In overall, the strengths of this book outweighed its weaknesses.
