Connecticut made considerable progress reforming the state child welfare system under the leadership of Commissioner Katz. In 2015, the Annie E. Casey Foundation, one of the leading organizations in child welfare issues in the U.S., published a case study that described changes at Connecticut's DCF as the "Connecticut Turnaround". In this report, they indicated that, "Over five years, Connecticut has made substantial progress in turning around its troubled child welfare agency. ... the state has instituted improvements, driven down the number of unnecessary child removals and ensured that children entering state custody live in families whenever possible, not in group placements."
