This final report describes objectives, activities, and outcomes of a project to provide training to infant specialists employed within a total of 16 infant intervention programs in New York State. The project focused on the acquisition of skills necessary to provide services under Public Law 99-457. Training content and procedures were derived from an earlier demonstration project at the University of Connecticut Health Center. The New York project provided training within each regional planning group through an institute format. An institute consisted of approximately 6 to 10 didactic and activity-based sessions on a specific intervention topic. Topics included the Individualized Family Service Plan; infant curricula; transdisciplinary teaming; and programming for infants, toddlers and their families. Five to 10 infant specialists were enrolled in each institute. Competency tasks provided one measure of program effectiveness. Other measures included pre-post questionnaires, self-rating scales, and consumer satisfaction questionnaires. The major portion of the document consists of appendixes, including a list of institute participants, sample evaluation instruments, details on each of the 16 programs served, evaluation results, an inservice training manual, and an article by Mary Beth Bruder and Tina Nikitas titled "Changing the Professional Practice of Early Interventionists: An Inservice Model To Meet the Service Needs of Public Law 99-457."
