Community Unit School District 300 Calendar 2026-2027

Community Unit School District 300 is organized around three broad high-school patterns—Dundee-Crown, Hampshire, and Jacobs—but its official feeder page is not a one-to-one progression chart. Liberty and Sleepy Hollow elementary schools appear in more than one pattern, and Dundee Middle School is listed under all three high schools. Students sharing an earlier campus can separate later, while each high school receives students from several elementary and middle-school communities. The district’s address locator identifies the route attached to a property; a school name carried forward from an older record does not.

Dual-language education overlays that geographic system. Entry rules differ by language background, with native English speakers beginning in kindergarten, and placement can change the campus used for part of the sequence. It does not establish general open enrollment among District 300 schools. An address determines a K–12 route that may split a cohort before high school, while an approved language-program placement can alter one portion of that route without replacing the district’s underlying boundaries.
