According to the Center for Law and Social Policy TANF legislation includes two rules specific to minor parents (parents under age 18). One rule requires that minor parents live in an approved arrangement, usually with their parents. The other rule requires that minor parents typically participate in education leading to a high school diploma or GED. This issue brief reviews how Illinois approached eligibility under the two minor parent rules, and it explores why and how Illinois moved forward with a transitional compliance administrative rule. It also examines the effect the rule has had--notably that the process led to a better understanding of minor parents' individual circumstances and thus led to fewer inappropriate denials.
