The Individuals with Disabilities Education Act has undergone revisions roughly every 5 years since inception. Despite these modifications, the academic and social outcomes for students with disabilities lag behind those of their regular education peers. Results-Driven Accountability (RDA) was initiated to improve special education outcomes and efficacy. This case study examined the implementation science framework used for RDA. The results surfaced successes and concerns with the implementation process and illuminated barriers unrelated to the RDA initiative but critical for implementation and scaling. The findings from this study may contribute to identifying best practices in large-scale systemic initiatives.
