What to weigh before you make an offer in Mascoutah:

Schools in Mascoutah, IL

Mascoutah is served by one K-12 unit district, Mascoutah Community Unit School District 19, so there is no separate elementary and high school district the way there is in Belleville or Shiloh. The complication here is the opposite one: the district is much larger than the city.

District 19 schools:

District 19’s attendance area covers Mascoutah plus unincorporated St. Clair County including Scott Air Force Base, and reaches into parts of Belleville. Wingate Elementary, which opened in 2015, is listed by the district as serving The Orchards, Plum Hill Estates, Brookhill Estates, Green Mount Manor and Wingate Manor. Families in those subdivisions have a Belleville address and attend Mascoutah schools through high school.

It runs the other way too. A rural address with a Mascoutah 62258 mailing address is not automatically in District 19. The district maintains a school boundary page, and that is the place to settle it for a specific parcel.

Sources: Mascoutah CUD 19 district and Wingate Elementary pages. School assignment must be confirmed by parcel address with the district.
