Sixty pre-service teachers were surveyed about their confidence, concerns, and efficacy for inclusive classroom teaching before and after a course on inclusive education. Some students experienced a practicum in an inclusive setting alongside the coursework, and some students did not. Both groups made significant gains in all dependent variables and their subscales from pre-to post-treatment. However, the students who experienced a practicum in an inclusive setting developed greater teacher efficacy in classroom management than those students with no practicum. Given the importance of successful classroom management to teacher retention and student success, the findings support the importance of high-quality inclusive practica as an essential feature of effective inclusive teacher preparation programs.
