Child care requirements and regulations are determined by individual state governments, and therefore vary widely throughout the United States. The federal government is not responsible for regulating who is required to obtain a child care license or what training is needed both to receive and maintain the license.
Child Care Aware of America has an interactive map of the United States that gives state-by-state requirements for child care licensing, available for viewing at Naccrra.org. The National Association for the Education of Young Children is an organization that educates child care providers in every state and issues accreditation to programs nationwide that adhere to their high standards. More information about the standards, and a list of NAEYC-accredited programs, is available at Naeyc.org.
