This study evaluates the quality of the English textbook for Grade XI of senior high school in Indonesia, titled Pathway to English Tingkat Lanjut, using a qualitative document analysis methodology. The research examines the textbook based on established criteria for high-quality English learning materials, including practical considerations, layout and design, activities, skills development, language types, and subject content. Data were collected through a systematic review of the textbook's structure, exercises, and content, which were then compared to pedagogical standards and best practices in English language teaching. The findings reveal that the textbook meets expectations in terms of practical considerations, layout, design, activities, and basic skills development. However, it lacks essential supporting materials such as workbooks and audio resources, which are critical for comprehensive language learning. It also provides a general overview of content rather than a detailed introduction and offers limited coverage of grammar and vocabulary, with no emphasis on natural pronunciation, authentic language usage, or diverse registers and accents. The grammar explanations are not concise or user-friendly, and the examples provided are insufficient for learners' needs. Moreover, the subject matter lacks variety, reducing its ability to engage and motivate students. These findings underscore the need for targeted revisions to address these shortcomings, aligning the textbook with modern pedagogical standards and enhancing its effectiveness in fostering real-life English communication skills. Future research should explore the integration of multimedia resources and evaluate the textbook's impact in classroom settings.
