This brief reviews the emerging practice known as marriage and relationship education (MRE) that is designed to promote healthy marriages and relationships between parents. It begins by explaining the goals of the Marriage-Plus approach to help more children grow up with their two biological, married parents in a healthy, stable relationship, and to help parents–whether never-married, separated, divorced, or remarried–to be financially capable and responsible and to cooperate, whenever appropriate, in raising their children. The brief discusses features of healthy marriages, societal trends affecting marriage, data indicating children benefit when parents have a healthy marriage or relationship, and components of MRE programs. Controversies over MRE programs are addressed and a chart is presented that delineates the opinions of proponents and critics of the MRE programs. Marriage facilitators and barriers are also described, and case studies are presented that highlight successful MRE programs. The brief closes with policy recommendations for governments and family service agencies, and a list of MRE resources. 35 references.
