Instructors with a high sense of inclusive teaching efficacy appear to create classroom climate where learners with a range of learning styles and abilities perform well. There is quite limited research on inclusive teacher efficacy, a construct gaining considerable attention by scholars globally. This transcendental phenomenological study of (n=17) education general teachers working in inclusive classrooms in three participating school districts located in Northeastern Ohio aimed to identify their perceptions regarding levels of self-efficacy developed through their lived experiences working in this environment. Data were collected through classroom through observations and semi-structured interviews. Results of the study were processed using thematic analysis. Six themes were identified: (1) teachers' confidence in their ability to provide rigorous and accessible instructions to all the students regardless of their level of ability, (2) technology, (3) cooperative learning, (4) whole group sessions, (5) Internet sources, and (6) institutional support. Overall, results showed that teachers had developed a high level of self-efficacy. The findings of the research were consistent with Bandura's theory of self-efficacy, the guiding framework for this study. Study findings prompted three recommendations for practice regarding the inclusive classroom: using collaborative learning to facilitate classroom learning and instruction; using technology as a vital tool in inclusion classrooms; using internet sources and ensuring adequate administrative support. Recommendations for future research include, replicating the study in other study contexts and quantitative studies on relationship among the six themes identified, teacher self-efficacy, and student learning outcomes.
