About O’Fallon Community Consolidated School District 90
An O’Fallon mailing address does not by itself establish residence in O’Fallon Community Consolidated School District 90. The PK–8 district borders several other public-school systems, and its own map is described as a guide; parcel and taxing-district information may be needed before the elementary or junior-high assignment can be interpreted.
District 90 operates five elementary schools and two parallel grades 6–8 junior highs, Carriel and Fulton. Students attend one or the other—Carriel is not a stage followed by Fulton. After eighth grade, responsibility passes to an independent high-school system, commonly O’Fallon Township High School District 203. The sequence begins with parcel-level district verification, continues through a District 90 elementary and junior-high route, and ends with a fresh high-school eligibility decision under another board.
