BROOKLYN - Officials and advocates are calling for the Administration for Children's Services (ACS) to prove how well it is doing its job in Brooklyn and the rest of the city.A recent report by the Department of Investigation said up to 10 children died because the organization didn't do its job. City Councilman Bill De Blasio (D-Brooklyn) and other advocates Monday will ask ACS to bring real-time information to a hearing in September, hoping to determine potential problems and avoid deadly outcomes.The information is being gathered through ChildStat. The program is modeled after the NYPD's CompStat, which tracks weekly meetings. The program was put in place after a 7-year-old girl died at the hands of her stepfather.Councilman De Blasio claims the information can probe if the way ACS investigates cases is improving, if field officers are facing the same problems and whether recent reforms have helped improve ACS.
