These two theme issues of "Impact" discuss inclusive education for children with disabilities at the preschool to first grade level and at the kindergarten to grade 12 level respectively. The articles present different ways that families and professionals include children with and without disabilities in educational and child care settings, with the common element in their success coming largely through collaboration among many people and agencies. The articles include: "Early Education: Which Path to Inclusion?" (Mary A. McEvoy and others); "The Struggle, the Reward: Two Families' Experiences with Inclusion" (Debra Carroll and others); "Infants, Toddlers, and the Integrated Community" (Linda Kjerland); "Early Intervention in Day Care Settings" (Mary Beth Bruder); "Integration: A Cooperative Effort" (Betty Kasel); "Social Interaction Training for Young Children with Disabilities" (Richard J.
