COLUMBIA, S.C. (AP) - The embattled director of South Carolina's Department of Social Services says she will begin personally inquiring about workers who are handling more than 30 cases.

Lillian Koller told a Senate panel on Wednesday that caseloads have improved but acknowledged the agency needs more people. She pledges to get a weekly report on employees whose caseloads exceed 30 and says she'll call county directors to ask why.

It is Koller's second appearance before a Senate panel investigating potential problems at the agency. It has met six times since January.

Senators are questioning the agency's reported average of six cases per worker. Senators say that number doesn't correspond with what they've been told. Employees have complained of high turnover because of the stress of being responsible for up to 100 cases.
