This study surveyed local interagency coordinating councils (LICCs) required under Part H of the Individuals with Disabilities Education Act concerning: the composition of council membership; information regarding frequency of meetings, membership turnover, and other demographic characteristics of the groups; and how well the LICCs are functioning, the tasks they have accomplished, and what remains undone. Nine diverse communities with varying sociodemographics and population/resource densities in three states (Colorado, North Carolina, Pennsylvania) were selected. A questionnaire, the Coordination of Infant-Toddler-Preschool Services Questionnaire, was sent to 57 individuals in groups responsible for service coordination, and 43 responses were received. Results are detailed and then analyzed in terms of a four-state model of the development of interagency groups. Responses indicate that positive outcomes of efforts by LICCs include a more efficient service system, improved quality of services, an increase in the number of children and families served, an increase in referrals, and a service system that is easier for families to use. However, LICCs appear to be avoiding the more difficult tasks, such as performing needs assessments of the service system and analyzing agencies' policies. Analysis suggests that the development of many LICCs has been thwarted in the early stages. (Contains 23 references.) (DB)
