The so-called CARE team named on Dec. 2 by Gov. Jan Brewer provided the latest update Monday.
It said nearly 2,400 children identified in the reports now have been seen and more than 2,000 cases have had a response.
The team is led by the head of the state's Juvenile Corrections department, Charles Flanagan.
Department of Economic Security Director Clarence Carter revealed the uninvestigated reports called into a hotline on Nov. 21.
He's placed five senior Child Protective Services workers on administrative leave while an investigation is underway on how the cases were illegally closed.
