DETROIT (AP) — A review of 20 Michigan home day cares found that each wasn't in compliance with at least one state licensing requirement for children's health and safety, according to a report released Monday by the U.S. Health and Human Services inspector general's office. Ten providers had not properly completed criminal background checks for assistant caregivers, according to the report, which was obtained by The Associated Press. "The (state's) licensing department does not often identify health and safety violations when they first occur or identify when a provider might need additional training," the report said. [...] some health and safety violations may exist several years before a state licensing inspector discovers a problem that places children at risk. Similar reviews have been conducted in other states to determine if day care providers receiving money through a federal fund that helps parents pay childcare costs are meeting health and safety requirements. The Child Care and Development Fund is designed for low-income families, families receiving temporary public assistance and those transitioning from public assistance to obtain childcare so they can work, receive training or go to school.
