Following a 5-year planning and development cycle, Illinois has completed its first year of full implementation of a statewide, comprehensive, coordinated system of early intervention services for eligible infants and toddlers and their families under provisions of the Individuals with Disabilities Education Act (IDEA). Among accomplishments noted are: adoption of mission and philosophy statements; use of IDEA funds to expand services at 56 sites; implementation of a statewide system of services; development and implementation of a public awareness program; enactment of the Illinois Early Intervention System Act; establishment of 45 local interagency coordinating councils; establishment of Interagency Agreements between the State Board of Education and seven participating agencies; establishment of a statewide network to coordinate diagnostic services; and appointment of an Early Intervention Ombudsman. Illinois activities and progress are reported in relation to the 14 components required by federal IDEA regulations. A description of each of 10 state agencies represented on the Illinois Interagency Council on Early Intervention is also provided. Additional information addresses interagency agreements, interagency coordination, additional early intervention activities, and the Federal fiscal year 92 budget/expenditure report. (DB)
