This brief introduces four research projects testing promising interventions funded under the Head Start University Partnerships (HSUP): Dual-Generation Approaches grant program. Two-generation approaches are typically designed to address problems associated with poverty by combining child-focused services with adult-focused services. Head Start programs provide a unique opportunity to serve as a platform for meeting the needs of children and families together. In this brief, the four HSUP grantees introduce their research projects, highlighting the goals and key features of each intervention, their approach to meeting the needs of children and parents together, and the targeted outcomes of the interventions. Future briefs will discuss implementation and impact findings. (author abstract)
