At a time of increasing and unprecedented homelessness--with more children and youth living without safe, stable housing than during the pandemic--schools are running out of time to use federal pandemic-era funds dedicated to helping homeless students. While the pandemic is officially over, the crisis of homelessness is unabated and growing. Without urgent action at all levels, an extraordinary opportunity to help some of our nation's most vulnerable students will be missed, prolonging and exacerbating broader educational challenges for schools and students. This report presents key findings from a national survey of school district homeless liaisons about the impact of and challenges using American Rescue Plan--Homeless Children and Youth (ARP-HCY) funds. Key findings include: (1) Child and youth homelessness has increased since the pandemic, creating a greater need for targeted support for students experiencing homelessness; (2) ARP-HCY funds have proven to be impactful in schools across the nation; and (3) Despite these positive impacts, a number of challenges are preventing ARP-HCY funds from helping vulnerable students at a time of heightened need. Recommendations are provided to Congress, the U.S. Department of Education, State Education Agency Leaders, Local Educational Agency Leaders, and State Legislatures to ensure that these funds are used effectively now and sustained into the future.
