This study explored the role of preparing teachers’ understanding of the co-teaching and collaborative teaching models. This research aims to significantly advance inclusive education practices by offering novel perspectives on the functions of co-teaching models and the preparation programs for pre-service teachers. This investigation employed a descriptive research technique to understand the essential elements and strategies of effective preparation programs for pre-service teachers that promote co-teaching and inclusive education, as perceived by teachers. A total of 30 individuals participated in the research project, consisting of 20 pre-service teachers in their last year of college and 10 full-time teachers in public schools in Saudi Arabia. The survey revealed that 80% of the pre-service teachers considered that peer-to-peer learning activities, such as group discussions and collaborative projects, were the most effective means of acquiring knowledge regarding co-teaching approaches. The comprehensive findings of this study challenge conventional notions regarding the preparation of teachers and highlight the urgent necessity of formulating novel and all-encompassing approaches for pre-service teacher training.
