Forty-two preschool children participated in this 2-year Head Start research project conducted at the University of Hawaii. The objectives of the overall project were (1) to focus interest on the need for early intervention with poorly-functioning preschool children with the intent to offer services of a preventive rather than remedial function; (2) to demonstrate the need for and value of an interdisciplinary approach to diagnosis and educational planning; and (3) to serve as a training function for prospective teachers and pediatric residents. Two other objectives were added for the second, or followup, year of the project: (1) assessment of the ability of the members of the original disciplinary team to predict success in school at the preschool level and (2) assessment of the progress of problem children who received the special education intervention. The objectives were successfully realized, and it was found that there was a need for more interdisciplinary services for children in Hawaii and a need for early identification of and educational and medical intervention with high-risk children.
