Firstly, we endeavor to introduce teachers and teacher educators to the fundamental principles of inclusive education, shedding light on the barriers, roles of stakeholders, and the foundational elements of teaching competency. By establishing this strong foundation, we then delve into the realm of inclusive teaching, exploring various models, the development of competencies, and their profound significance in creating an inclusive learning environment that nurtures the growth of all students. Furthermore, this book serves as a practical guide, providing step-by-step processes and illuminating examples for developing competency models. Through comprehensive frameworks, we elucidate the various domains, areas, and elements that comprise inclusive teaching competency. Moreover, we provide behavior indicators that correspond to different stages of competence, offering educators a valuable resource for observing and evaluating their own inclusive teaching practices. This inclusive behavior indicator table, carefully crafted and thoughtfully presented, facilitates the assessment of teachers' inclusive teaching competency, paving the way for professional growth and improvement.
