This foundation guide is addressed to Head Start staff, parents, and consultants to help them develop a broader view of their roles and to support the program's efforts to include children with disabilities in the various worlds around them. The guide includes the following sections: (1) "Module 1: There's Room for All of Us," which helps participants identify ways in which their own perceptions and experiences influence how they interact with children with disabilities and their families; (2) "Module 2: Communication Counts," which helps participants identify and practice ways of communicating about disabilities that foster a sense of belonging in children with disabilities and their families; (3) "Module 3: Making It Work!" which helps participants identify how the principles underlying the laws and regulations that protect the rights of individuals with disabilities apply to everyday practice; (4) "Continuing Professional Development," which offers strategies that supervisors can use to help staff apply new skills and extend their learning; and (5) "Resources," which lists print and audiovisual materials and resources that staff can use to learn more about the key issues presented in the guide.
