This document presents general information about State Interagency Coordinating Councils (SICCs) which participate in the Early Intervention Program for Infants and Toddlers with Disabilities (formerly Part H Program, now Part C) under the Individuals with Disabilities Education Act (IDEA). The information was gathered from questionnaires returned from 42 out of 57 states and jurisdictions. It reports on topics such as: each SICC's composition and membership; parent roles and participation; strategies for outreach to underserved populations; structure and organization; roles and functions; and SICC documents available to share with other SICCs. Each section contains a summary of respondents' comments. Also included is information about local or regional interagency coordinating councils and their relationships to the SICCs. The primary purpose of the document is to share this information among SICC chairs and to provide examples of successful practices. The information is also to be shared with the broader early childhood community. Contact information for the chair or co-chairs of each SICC is given and the full text of those portions of the Code of Federal Regulations (CFR), issued by the U.S. Department of Education under IDEA, which pertains to SICCs is provided.
