The mission of the Center of Families, Communities, Schools & Children's Learning is to conduct research, evaluation, and policy analyses aimed at increasing knowledge about how families, schools, and communities influence student motivation, learning, and development, as well as how to strengthen the connections between these three major social institutions. This report examines federal and state efforts to deliver comprehensive family services through interagency cooperation and family empowerment policies. An introductory section defines comprehensiveness, collaboration, and empowerment, provides a typology of family and community involvement activities, and describes the Center's focus on reviewing policies in four promising areas: Service Integration; Easing Transitions from Early Childhood To School; Parent Involvement in Education; and Migrant and Homeless Families. These are the subjects of the four main sections of the report. They examine: (1) service integration initiatives involving families in collaboration and empowerment, using programs in Florida as examples; (2) selected federal and state efforts to support the transition from preschool to kindergarten through collaboration and empowerment, citing initiatives such as Head Start and New Jersey's GoodStarts; (3) empowering families through comprehensive parent involvement policies, including Chapter 1 programs, special education, Head Start, Even Start, and the Kentucky Education Reform Act; and (4) federal and state efforts to provide comprehensive services to migrant and homeless children in Texas, Michigan, Florida, Minnesota, and Illinois. A concluding section presents some lessons learned from past programs and proposes solutions to specific difficulties of comprehensive, collaborative, and empowering initiatives. An appendix provides a list of organizations advocating service integration, school transition programs, comprehensive parent involvement, and migrant and homeless programs. (MDM)
