This document is designed to enlarge and expand the intergenerational community service mission and serve as a practical tool to anyone (including policymakers and program planning professionals) who wishes to learn about or start intergenerational community service programs (ICSPs). The following ICSP topics are discussed: rationale (building citizenship and understanding in a diverse society); best practices (guiding principles, components, myths); planning (assessing needs, engaging community partners, setting goals/objectives, selecting projects defining roles, developing a resource and funding base); implementing (recruitment, participant orientation and training, sample activities); sustaining (support, community visibility, dissemination, program evaluation); the state of the art (Delta Service Corps and Partners for Tomorrow); and tips from three ICSP experts (Billie Ann Myers, John Briscoe, and Lynn Thornton). Appended are the following: 97-item annotated bibliography; annotated list of 11 selected ICSP specialists; contact information for 17 featured programs; information about national/community service grants, the National Senior Volunteer Corps, Title V of the Older Americans Act, and selected multicultural organizations and organizations serving persons with disabilities; and exercise for building intergenerational understanding.
