The Model Classroom Initiative (MCI) was conceptualized to improve learning and IEP goal attainment while decreasing maladaptive behaviors in specialized instructional program classrooms. The MCI Coaching Model was utilized to assist teachers with the implementation of MCI components in three specialized instructional program classrooms, all of which served students with autism and developmental delays. Data were collected using Innovations Configuration Maps, observations, coaching, surveys, classroom data, and interviews and were analyzed using a mixed methods approach. Results indicate that the MCI coaching sessions increased participant teachers' feelings of support and being heard and slightly decreased stress, increased the implementation of the chosen components for two of the three teachers, increased the knowledge of and confidence in the MCI components, and increased the teachers' perception that the coaching helped to increase the students' academic, behavioral, and Individual Education Plan (IEP) goal progress.
