This final report describes the Inclusion through Transdisciplinary Teaming (ITT) project, which provided support to personnel working in schools, child care centers, and Head Start programs as they designed and provided services that included young children with disabilities and their families. During its 3 years of outreach, ITT project staff offered 64 workshop presentations or on-site consultations where 1,787 individuals were trained or received technical assistance. The ITT model used strategic management theory to facilitate design and delivery of services within the primary target sites. An instrument, "Planning for Successful Inclusion," (PSI) was developed to help organizations produce change, facilitate the self-evaluation process, and focus on continuous improvement of quality services. Training and consultation were individualized to meet the needs of each site. Individual sections of the report describe the project's goals and objectives, theoretical framework, methodological problems and resolutions, and future activities. Extensive appendices include a list of instruments reviewed, the PSI Table of Contents, sample action plans, a sample of data collected, the training evaluation tool and data summary, and data on the use of the PSI by sites.
