The final report of the Health Start evaluation of the second year program is presented in three separate documents. This paper presents an overview of the Urban Institute's evaluation of the Health Start program and covers two broad areas: health service coordination and health service delivery. The two major questions for the 1972-73 evaluation were the following: (1) How can health services for low-income children best be coordinated?, and (2) What are some innovative ways to provide health detection, treatment, entry into an on-going program and education that could be adopted by summer and full-year Head Start programs? Recommendations made as a result of the evaluation study were to strengthen federal program management and to design the Health Start program to yield more useful information. Limitations of the evaluation study are noted. The appendix presents an overview of the health service component of the Health Start program. (CS)
