Districts across the country are using federal COVID relief aid to bring mental health professionals into schools. But this unprecedented infusion of federal aid also creates a challenge: how to sustain new school staff positions when the funding expires at the end of 2024. In this analysis, Phyllis W. Jordan and Bella DiMarco of FutureEd, an independent, nonpartisan think tank at Georgetown University’s McCourt School of Public Policy, and Anne Dwyer of the McCourt School’s Center for Children and Families explain how Medicaid, the federal-state partnership that already provides health care for millions of public school students, could be part of the solution - as long as states take the necessary steps to use it and federal agencies back them up.
