This booklet presents licensing standards for day and night care centers as updated by the Illinois Department of Children and Family Services with the aid of a federal grant from the Office of Child Development to the State of Illinois. These standards provide broader coverage in existing areas as well as expanded coverage for school age children, transportation, infant care, special children and nutrition. The standards and compliance requirements in this document are designed to be brief, concise, understandable and enforceable, with as little subjective interpretation as possible on the part of all who read and use them. The standards also reflect administrative experience with the revised 1971 licensing standards. Standards are grouped under the following broad headings: philosophy; licensure, organization and administration; personnel; services to children; plant and equipment; and records and reports. The Child Care Act of 1969 is included in this document. (MS)
