The report details accomplishments of Texas's Early Childhood Intervention (ECI) program and describes the program's interagency organization and services. The history of early intervention in Texas is traced and the need for early intervention documented. Interagency cooperation among the departments of health, mental health and mental retardation, human resources, and education is emphasized. Program components are reviewed including the advisory committee, public awareness and training opportunities for service providers, monitoring and evaluation, and service delivery in areas without funded programs. Among ECI services discussed are those that represent individualized, comprehensive, and quality levels of services. Effectiveness data are reported from a random sample of 558 children and their parents. Data cite child progress and increases in parental ability to help train their children. (CL)
