The goal of this study was to see how well the "Bahasa Inggris" textbook met Alan Cunningsworth's eight criteria for a good textbook: Aims and Approaches, Design and Organization, Language Content, Skills, Topic, Methodology, Teacher’s Book, and Practical Consideration. The study employed a descriptive qualitative method, which is also known as content or documentary analysis. The results show that the textbook fits the majority of Alan Cuningsworth's criteria, which are Aims and Approaches, Design and Organization, Language Content, Skills, Topic, Methodology, and Practical Consideration in Bahasa Inggris, but there is no teacher's book included in the course package. Bahasa Inggris is a decent textbook with a total score of 71.79 percent. The textbook can still be utilized to teach English in Vocational High School, according to this study, but it is not the only source of material. It is preferable for teachers to supply more resources. Furthermore, if it is possible to meet Cunningsworth's requirements for an excellent textbook, the author of the Bahasa Inggris textbook can rewrite the textbook.
