This research brief builds on existing guidance about supporting children and families during the transition to kindergarten by broadening the way parents and stakeholders think about this transition to include the school-age programs many young children attend. During their child’s early years, working parents of low income may have used child care subsidies through the federal Child Care and Development Fund (CCDF) to obtain full-day child care, or sent their child to a part-day Head Start program that used CCDF funding to offer extended-day coverage to children from qualifying families. The shift from this type of comprehensive child care coverage to a much-shorter school day schedule means working parents must secure additional child care and prepare their children for the transition to these new care arrangements as well as to kindergarten.
