The expanded prekindergarten programs in Georgia, Oklahoma, New York, and New Jersey had some similarities in their design features. For instance, programs were offered at no direct cost to parents, regardless of family income, and each state incorporated some level of collaboration with community-based providers such as Head Start and large child care facilities. Some key differences in their design features also existed. For example, Georgia and Oklahoma had statewide programs providing prekindergarten services to over half of their four-year olds, while New York’s and New Jersey’s programs were more geographically targeted. States and school districts also varied in offering full- or half-day prekindergarten programs.
