The New York State Office of Mental Retardation and Developmental Disabilities initiated a project to produce a description of existing state and local programs and models of service delivery for early intervention services for children aged 0-5. A survey of 72 public and private service providers in 12 New York counties determined that 11,185 children were served, 15.9% of whom were identified as at risk for developmental delay. Early intervention services available were categorized as: entry services, direction services, and specialized services. Measures of capacity/coordination indicated that some counties needed increased capacity, and others showed a greater need for coordination than increased capacity. The largest single referral source was pediatricians. The mean age at start of services for all children in the sample was approximately 2 years, 6 months. The mean waiting time for services was approximately 1.5 months, while the median waiting time was 1 month. Inadequate transportation services did not appear to be a major problem. A rating of problems indicated that major problems were the lack of a legislative mandate which clearly indicates responsibility for this population and inadequate community education regarding the needs of disabled children and their families.
