This final report describes Project I-TIP (Inservice Training for Infant Personnel), a 3-year project which developed and demonstrated a comprehensive model of inservice training for personnel serving children with handicaps (ages 0-5 years). Specifically the project provided training at 17 sites to over 900 individuals. Training protocols were developed on a variety of topics including a language enriched environment model. A model for inservice training was developed and implemented using a needs assessment technique called, "build a model." Using a case study approach to analyze each program system, the project developed a working model to classify program needs according to Maslow's hierarchy of needs and to identify critical factors which influence the success or failure of staff development efforts. Project participants evaluated the program as extremely effective and useful. Individual sections of the report address: goals and objectives; conceptual framework; training model activities and participants; project evaluation; need for continuing inservice training opportunities; and products.
