A workload study was conducted for the Child Safety and Permanency Division to develop time standards for investigative, in-home and permanency caseworkers. Using the results of the study, HZA developed an analytic tool which enables counties to correlate staffing need with the ability to achieve positive outcomes for children and families. In the U.S. Department of Health and Human Services' Issue Brief "Caseload and Workload Management," April 2010, HZA’s study conducted for Minnesota is described along with the Workload Analytic Tool. The Child Welfare Information Gateway reports the "tool has been well received by county administrators who described it as 'awesome' and found it useful in considering staff workloads." The tool is described as “an innovative and easy-to-use tool to help counties manage their child welfare workloads.
