The right to attend school tuition-free at New Trier High School is extended to residents who live within the District 203 boundaries. To be a legal resident of District 203, a student must reside with one of the following:
- Natural or adoptive parents listed on the birth certificate
- An adult that receives public aid on behalf of the student
- An adult who has assumed and exercises responsibility for the student and who provides him/her a fixed, 夜间的住所. The student must eat and sleep at the adult's residence on a regular basis.
Property owners in District 203 who do not live at the property are NOT legal residents and their students DO NOT QUALIFY to attend school on a tuition-free basis.
