Extensive reading (ER) is a valuable yet often overlooked approach to improving English proficiency, particularly among Information Technology students who primarily engage with technical content. This mixed-methods study at Ho Chi Minh University of Industry and Trade investigates ER’s impact on vocabulary acquisition, reading comprehension, and language development. Data from 150 students, collected through surveys and interviews, explore their reading habits, challenges, and perceptions of ER. Findings emphasize ER’s role in academic success and professional communication, highlighting its adaptability to technical education. The study also identifies barriers such as low motivation, limited reading materials, and time constraints, while proposing strategies for integrating ER into the curriculum. This study offers insights into adapting ER for technical education, equipping students with essential English skills. Ultimately, this study aims to foster a reading culture that enhances language proficiency and prepares students for global career opportunities.
