In response to economic distress, schools are increasingly serving as providers and distributors of social service resources. However, even when schools offer resources that respond to needs, they struggle to attain high levels of uptake. We examine the family-level correlates of participation in school-sponsored resources during the early months of the COVID-19 pandemic and find that uptake increases with economic need. In addition, net of need, families who report maintaining communication with parents of their children's classmates take up more resources; and take-up of key meal and digital technology resources is associated with higher levels of take-up of other resources. These findings contribute to efforts to reposition schools as social service hubs by highlighting promising practices to improve resource uptake.
