This final report describes a 3-1/2 year project to establish model technology assessment procedures and to train early intervention personnel and families of young children with moderate to severe disabilities to function as effective members of a core assistive technology assessment team. The project's outreach goals focused on stimulating services via dissemination, training and replication, assisting states, providing state-of-the-art product development, and serving as a national technology assessment resource. Training materials developed included written and multimedia materials, procedures for assessing appropriate applications for specific children, examples of follow-up activities, case studies of children, and suggestions for problem solving. Evaluation found the program effective in four areas: (1) appropriateness of the process and recommendations for this population; (2) positive outcomes for children and families; (3) child progress reported by families; and (4) child progress reported by teachers. Overall, the project's replication and continuation sites directly affected 697 children and their families, and over 1,241 people attended project presentations at conferences. Individual sections of this report describe the project's goals and objectives, its theoretical and conceptual framework, its major features, problems and solutions, evaluation, and impact. (DB)
