This pamphlet provides an overview of current research on home-school collaboration and strategies that schools can use to develop partnerships with their students' parents or guardians. An introduction lists the benefits of increasing parent involvement (higher grades and test scores, long-term academic achievement, positive attitudes and behavior, more successful programs, and more effective schools). Section 1 describes three approaches to parental involvement (influencing parent-child interaction at home; involving parents in specific programs within the school; and creating a systematic and comprehensive relationship between parents, the school, and the community). That section also states research findings concerning each of the approaches and discusses the role of the educator in home-school partnerships, the role of the school, and critical issues in parent involvement. Section 2 suggests strategies that can be grouped into five categories (home-school communication, parents as supporters, parents as teachers, parents as learners, and parents as advisors and decision-makers). This section also includes strategies to involve the hardest-to-reach parents (parents who work outside the home, low-income parents, single parents, divorced parents without custody, and parents of minority race or language). Section 3 describes 12 parent involvement programs in Massachusetts. The document concludes with a 24-item bibliography. (CML)
