This article describes the development of an English language textbook evaluation checklist. The researchers first reviewed existing textbook evaluation checklists and identified common criteria. They then developed a tentative checklist organized into two main categories: general attributes and learning-teaching content. The general attributes section includes subcategories like relation to syllabus, methodology, suitability to learners, and physical attributes. The learning-teaching content section includes criteria for areas like listening, speaking, reading, writing, vocabulary and grammar. The researchers considered issues of validity, reliability and practicality in developing the checklist. They intend to further refine the checklist through additional research studies. The checklist is intended to help educators evaluate and select textbooks.
