This study investigates the impact of professional development programs in English Language Teaching (ELT) on the quality of instruction provided by EFL instructors and the subsequent impact on students’ academic achievement in Saudi universities. The hypothesis suggests that higher educational attainment results from instructor professional development. The researcher used a questionnaire to gather ideas, perspectives, and opinions from English language instructors at Saudi universities. Findings indicate that continuous professional development is essential and influences instructors’ effectiveness, the quality of educators, and students’ academic achievement. Implementing new ideas and methods inspires instructors, improves their capacity to address students’ needs, and results in improved instruction and student achievement. Recommendations include instructors being lifelong learners, using effective techniques and tools to assess programs, and considering cross-cultural perspectives in future research comparing studies in Saudi Arabia and other countries.
