This study aimed to develop secondary stage students’ EFL oral communication skills via a proposed program based on integrating flipped classroom and inquiry learning. No previous studies dealt with this program, which is based on integrating flipped classroom and inquiry learning, so this is the novelty point of the current study. The quasi-experimental design of two groups was adopted. There are forty participants for the experimental group and the same for the control group. Questionnaire on oral communication was designed and juried. Then, the oral communication test was juried and administered to the participants of the two groups. The program was designed and administered in the second term of the academic year 2022/2023 and lasted for the entire term with two sessions per week for the experimental group. The study results revealed that the experimental group’s post-results exceeded its pre-results in the post-administration of the instructions. Furthermore, it could be determined that the proposed program substantially enhanced the stated variable.
