Preparing educators to teach in inclusive classrooms is a critical first step in ensuring that all students in P-12 programs receive exemplary educational services. The need to restructure personnel preparation in response to the increasing diversity and inclusiveness of public school classrooms has evolved from discussion and debate more than a decade ago to an array of initiatives in teacher education programs across the country today. In the Department of Teaching and Learning at Northern Illinois University, Project ACCEPT (Achieving Creative & Collaborative Educational Preservice Teams) was developed in response to implementation of standards-based certification requirements for special and general education teachers in Illinois as well as recognition within the college and department that new teachers would benefit from program enhancements focusing on education of all learners. The primary goals of Project ACCEPT were to prepare educators for inclusive schools and to encourage collaboration across different disciplines. This article presents a study that examines the impact of Project ACCEPT on the attitudes, knowledge, skills, and in-service performances of participating special and general educators.
