While the charter sector has much to celebrate, the country can do more to put great schools—including excellent charters—within reach for our most vulnerable students. Students with disabilities represent one such group. The best solutions start by partnering with the parent groups that advocate for students with disabilities, and have been doing so for decades. As partners, charter school champions and organizations working with parents of children with disabilities can collectively improve outcomes for students with disabilities, create better school options for them, and advocate for better policies. This call to action for charter champions to launch and deepen their partnerships with parent advocates explains how they are better together—why such partnerships are needed, the forms they might take from partnerships highlighted in Washington, DC, New York City, and Los Angeles, and how to get started.
