MADISON, Wis. (AP) -- The number of complaints against licensed daycare centers in Wisconsin has risen 30 percent in the last seven years.

But state officials say that's largely because parents are becoming more involved.

The state received about 1,150 complaints in 2000. Last year that number jumped to almost 1,500.

Jill Chase is a director with the Department of Health and Family Services. She says one reason for the increase is that parents are learning to take an active role in their children's care.

She says 40 daycare providers had their licenses revoked in 2007.

Chase calls it an "average number" and estimates one in 10 valid complaints last year involved unlicensed providers.
