Arizona's struggling child-welfare agency faces a continuing increase in its backload of cases while the number of caseworkers remains short of the state's own standards.

Those are among findings in two new reports on Child Protective Services' workload and staffing during the past half-year.

The Arizona Republic reports that the studies are being reviewed as lawmakers work on a new state budget.

Gov. Jan Brewer is requesting $70 million of additional funding for CPS and related state programs that provide foster care and adoption services. She signed emergency legislation in January to give C:PS $4.4 million for immediate hiring of 50 caseworkers.

The reports say CPS is still short of meeting caseload standards. Meanwhile, there's a backlog of just under 13,000 inactive cases, up from 10,000 in mid-2011.
