INDIANAPOLIS (AP) — The director of the Indiana Department of Child Services says the agency is seeing a higher percentage of its family case managers leave the department.

Mary Beth Bonaventura spoke Thursday to the DCS Oversight Committee. The Indianapolis Star reports that agency records show September’s turnover rate of 24.1 percent is the lowest since at least 2007. That rate was 21.7 percent over the last fiscal year.

Bonaventura said case managers are leaving because of higher caseloads.

DCS has responded by adding 213 family case managers positions this year, but 75 of those jobs haven’t been filled. Bonaventura says state officials are determining which regional offices need those positions.

State law requires case managers handle a certain of cases at once. Just one of 19 DCS regions complies.
