High school students in Indonesia face challenges with Extensive Reading (ER) due to limited materials, a test-focused curriculum, and low reading motivation. Intensive reading dominates classrooms, leaving little space for reading for pleasure. This study explores ways to integrate ER in schools using a qualitative approach, including case studies, teacher interviews, and classroom observations. Data from teachers and students highlight effective strategies such as graded readers, digital libraries, and student-led reading groups. Findings show that encouraging book selection, storytelling, and discussions boosts engagement, while using students’ first languages improves comprehension and confidence. Collaboration among teachers, schools, and communities is essential for building a strong reading culture. The study emphasizes the benefits of ER in enhancing fluency, vocabulary, and comprehension. Future research should examine long-term ER programs and their impact on multilingual literacy development.
