Each year, child welfare agencies make over 40,000 requests for home studies to determine whether children in foster care can be placed with parents, relatives, and others living in another state. Each request is governed by the Interstate Compact on the Placement of Children (ICPC), a uniform law adopted by every state to coordinate the placement of foster children in other states. Under the ICPC, a child can only be placed in foster care in another state after the receiving state conducts a home study and approves the proposed placement. Despite its good intentions, the ICPC has become unworkable...A study I performed with support from the Annie E. Casey Foundation sought to gain a better understanding of these problems by obtaining data from states to answer basic questions about the ICPC.
