The law will establish a new set of quality indicators for child care providers.
The quality indicators will help parents know if a child care provider meets certain criteria including, state licensure, health and safety requirements, use of curricula, additional staff training and any history of violations.
Senate Bill 869 and House Bill 1831 call for the Department of Social Services to establish a website detailing health and safety requirements, inspections and any history of violations by child care providers who receive state or federal money.
The law also calls for a hotline to be set-up for parents to submit complaints about child care providers.
Providers who care for four or fewer children will have to comply with safety, fire, health and building codes and be subject to tuberculosis testing and unscheduled on-site monitoring.
"The health and safety of our children is of paramount importance, and I appreciate the General Assembly working together in a bipartisan way to get this critical legislation to my desk," Gov. Nixon said. "These quality indicators will give parents the tools and information they need to choose the right child care provider for their family."
The new indicators will go into effect in the fall of 2015.
