The nation's six million students with disabilities have graduation rates nearly 25 percent lower than their general education peers and significantly lower postsecondary enrollment and completion rates. For the last decade and a half, state policy leaders have decried No Child Left Behind's lack of flexibility and one-size-fits-all design for failure to meet these students' needs. With the passage of the Every Student Succeeds Act (ESSA), states will have greater flexibility and responsibility for these students' outcomes, and they should take this opportunity to better meet their needs. This policy update is part of a series that suggests strategies that state boards of education can use to address the challenges and inequities facing some of the most disenfranchised, at-risk student populations in the country. While a one-sized-fits-all system affects many students that learn differently, it poses significant problems for students with disabilities through its lack of personalized learning, low expectations, lack of accommodations for assessments, and gaps in accountability and educator capacity. In this policy update, ESSA addresses all of these issues and offers states and school districts opportunities to enhance their education systems in these areas.
