This study investigated the attitudes of Saudi female EFL students and teachers, and the barriers to the uptake of the extensive reading program at a preparatory year program in Saudi Arabia. In order to enhance the effectiveness of the extensive reading research, a mixed method research design was employed using an online questionnaire followed by semi-structured interviews in a Saudi university context. 111 Saudi female EFL students participated in the questionnaire. The quantitative result revealed positive attitudes toward extensive reading. It found that students understand the benefits and importance of reading extensively in the English language. In addition, interviews with six Saudi female EFL students and two Saudi female EFL teachers further demonstrated that students possess positive attitudes toward extensive reading programs supporting the quantitative findings. However, the qualitative interviews also highlighted the barriers to extensive reading related to the materials, students, teachers, program, and culture. Limitations, suggestions for the improvement of the existing extensive reading program at PYP, and recommendations for future research are also included.
