The main purpose of the Child Care Workforce Act is to improve the availability and quality of child care services in the United States. It aims to achieve this by providing funding to states and tribal organizations to enhance the wages of child care workers. The ultimate goals are to attract and retain more child care workers, improve their well-being, and make child care services more affordable for families. Key provisions of the Act include the establishment of a pilot program that offers competitive grants to states and tribal organizations.
