This report provides information on the content, impact, and characteristics of over 50 model intergenerational programs across the United States. It is organized along a continuum starting with programs involving the most physically capable and mobile persons and moving toward those in which the older person is in increasing need of support and service. The report provides (1) ideas for types of intergenerational programs that might be appropriate responses to local needs, (2) models of sound practice, (3) information about individuals, organizations, and clearinghouses that provide expertise in special program areas, and (4) resources on program development. Programs in the first section describe complementary ways in which the need for suitable child care has been met by older persons needing stimulation, social contact, and/or added income. Fifteen programs incorporating intergenerational programs into elementary, secondary, and higher education are described in the second and third sections. The fourth section focuses on the supportive role played by many older persons in their relationships with children and youths who are "vulnerable" (e.g., abused and/or neglected children, juvenile delinquents, and runaways). Subsequent sections describe programs involving older persons in political action and community planning; arts, humanities, and enrichment; home sharing; grandparenting; chore services and employment; and informal family and community supports. A final section on the role of state units on aging in stimulating and promoting intergenerational programs is followed by an index of projects by title. (LH)
