Promoting family economic security and mobility requires collaboration across key systems that serve families. This report describes opportunities for the early childhood and higher education systems to support each other's key goals for system advancements to increase economic mobility among America's families. It provides examples of early education/higher education partnerships at multiple levels that use a variety of funding sources and that often benefit from leaders and champions who understand the importance of addressing families' postsecondary and early education needs in an integrated fashion. This report also provides a set of principles and recommendations for establishing effective partnerships, informed by the guiding voices of parents. Engaging leaders at all levels, improving data availability, and modifying policies to improve the flow of information, supports, and resources available to families, programs, institutions, and innovative partnerships are key steps to integrating systems to better support families.
