About Downers Grove Grade School District 58
Downers Grove Grade School District 58 moved to a K–5 elementary and 6–8 middle-school structure for 2026–27. Sixth grade had previously remained in the elementary system, so older directories and school-supply materials can describe a route that no longer applies.
Students now leave elementary school after fifth grade and attend Herrick or O’Neill for all three middle-school years. Assignment between the two remains boundary-based; the reconfiguration did not create open choice.
El Sierra houses the district’s two-way dual-language route. The program reaches grades K–4 in 2026–27 and is designed to add a grade as its cohorts advance. Entry and continuation follow program rules, so a language-program placement can change the elementary campus without changing district residency.
After Herrick or O'Neill, governance passes from District 58 to an independent high-school district. Most students then enter Community High School District 99, whose North–South line is independent of the District 58 elementary and middle-school map. For 2026–27, sixth grade moves into Herrick and O'Neill; El Sierra placement and the later District 99 high-school boundary continue under their own rules.
