Amends the Children and Family Services Act. Redefines the term "children" to include persons under the age of 23 (rather than 21) who were committed to the Department of Children and Family Services pursuant to the Juvenile Court Act or the Juvenile Court Act of 1987 and who continue under the jurisdiction of the court. Requires the Department to provide or authorize child welfare services, aimed at assisting minors to achieve sustainable self-sufficiency as independent adults, for any minor eligible for the reinstatement to wardship pursuant to the Juvenile Court Act of 1987, whether or not such reinstatement is sought or allowed, provided that the minor consents to such services and has not yet attained the age of 23 (rather than 21). Makes conforming changes in the Juvenile Court Act of 1987, the Illinois Identification Card Act, and the Medical Assistance Article of the Illinois Public Aid Code.
