The purpose of this Information Memorandum (IM) is to strongly encourage all child welfare agencies and Children’s Bureau (CB) grantees to work together with the courts and other appropriate public and private agencies and partners to plan, implement and maintain integrated primary prevention networks and approaches to strengthen families and prevent maltreatment and the unnecessary removal of children from their families. Coordinated and robust primary prevention efforts are critically important to strengthen families, prevent the initial occurrence of and ongoing maltreatment, prevent unnecessary family disruption, reduce family and child trauma, interrupt intergenerational cycles of maltreatment, and build a well-functioning child welfare system.
