The concept of parent engagement has been used to describe parent behavior, expectations, and activities that have the potential to promote children's learning and development. Here the term is used to refer to parents' support for their young children's learning fostered through relationships with child care and early education programs and providers, which includes parent engagement with programs, as well as their involvement in their children's learning activities. This Topic of Interest highlights a recent review of research on the role of parent engagement in promoting young children's early mathematics and literacy skills and social-emotional learning. Other resources examine parent engagement in the context of Head Start programs, features of family-provider and family-program relationships that may influence parent engagement, and opportunities to strengthen parent engagement through state policies. This Topic of Interest includes journal articles, reports, data sets, and webinars from the Research Connections collection published since 2010. (author abstract)
