Despite its importance to achieving positive outcomes for vulnerable children and families, use of evidence by child welfare managers and practitioners remains limited. This study describes four types of organizational supports that child welfare agencies may use to facilitate evidence use. Data collected in 2016 from a six-state sample of private child welfare agencies are used to examine agency investment in different supports for evidence use and their association with managerial evidence use. We also identify contextual, organizational, and managerial factors associated with agency investment in these supports. Findings suggest that technical infrastructure is necessary but not sufficient for promoting managerial evidence use in the absence of other supports. Implications for policy and practice are discussed
