The Illinois Class 1 Eligibility Bulletin is a document issued by the Illinois Department of Human Services (IDs) that outlines the eligibility requirements for Illinois residents to receive assistance from the state. This bulletin explains the eligibility criteria for a variety of programs, including the Supplemental Nutrition Assistance Program (SNAP), Temporary Assistance for Needy Families (TANK), Medicaid, and the Children's Health Insurance Program (CHIP). It also outlines the rules and regulations that must be followed when applying for and receiving these benefits. There are two types of Illinois Class 1 Eligibility Bulletins: the "Public" bulletin, which is intended for public use, and the "Contracted Services" bulletin, which is intended for contracted service providers.
