This final report describes activities and achievements of Project TIE (Teams in Early Intervention), which developed, implemented, and evaluated an inservice training model to increase the competencies of team members from different disciplines as well as parents. The project was designed to assist in the implementation of Public Law 99-457 (later incorporated within the Individuals with Disabilities Education Act). The project was intended to impact early intervention services at the state level and and at the community-based early intervention program level. Project staff accomplished their goal by: (1) providing training of early intervention teams within a community; (2) developing training materials based on competencies needed by all team members; (3) developing training materials based on critical competencies needed by individual disciplines; (4) providing technical assistance and support; (5) disseminating effectiveness data and training materials; and (6) securing funding for Project TIE Outreach. The project developed four discipline-specific training modules, for health care professionals, occupational and physical therapists, speech language pathologists, and parents. Three model demonstration sites received assessments of their teams' procedures and training needs. Additional dissemination activities resulted in nearly 110 training activities throughout the U.S. Appendices include a discussion of the performance competence model, a description of the development of "community maps" showing various agency interactions at the Santa Fe (New Mexico) site, and two competency exams used in the program.
