Given the importance of evidence-based practices (EBPs) for improving outcomes for students with disabilities, it is key that preservice special education teachers have the opportunity to implement EBPs with high levels of fidelity during their teacher preparation program. For this reason, the authors conducted a systematic review of the literature to answer the question: Does providing performance feedback improve preservice special education teachers' fidelity of implementation of EBPs and outcomes for students with disabilities? Five studies were found which met inclusion criteria. These studies demonstrated a clear functional relationship between performance feedback and preservice teachers' increased fidelity to the EBP(s). Across studies, there were mixed effects in student outcomes when preservice teachers increased their fidelity to EBPs. Limitations of the current analysis and the included studies are discussed along with future implications for researchers and practitioners.
