What ought authorizers do to ensure that the charter schools they approve provide a quality education to students with disabilities who enroll in their school? That is the question many authorizers wrestle with as they strive to strike a balance between fulfilling their responsibilities under the Individuals with Disabilities Education Act (IDEA) while providing the autonomy that is central to the charter school ideal. As the gatekeepers monitoring entrance to the charter sector and, thereafter, the groundskeepers responsible for ensuring the maintenance of quality programs, authorizers are charged with making certain that applicants demonstrate the capacity to operate a quality school and then holding them accountable for doing so. Consequently, authorizers are uniquely positioned to ensure that charter school operators can adequately address the challenges associated with providing quality special education programs. This Issue Brief is the second in a two-part series on navigating special education in the charter sector. The first brief introduced the key constructs underlying the provision of special education in charter schools and identified strategies charter schools are using to build capacity to provide special education and related services. This installment, based on a decade of research on special education in the charter sector, outlines tangible steps authorizers can take to assess applicants' ability to meet special education obligations, support the development of special education capacity in charter schools and hold charter schools accountable for delivering quality special education programs.
