About Community Consolidated School District 21
Community Consolidated School District 21 currently assigns prekindergarten-through-eighth-grade students through an active address map covering portions of Wheeling, Buffalo Grove, Arlington Heights, Mount Prospect, Prospect Heights, and Northbrook. At the same time, a community Map Design Committee is developing possible future configurations.
The two timelines are explicit. Current registration continues under the existing map, while any redesigned map would take effect no earlier than 2027–28 and only after board approval. Drafts and community scenarios belong to the design process rather than the 2026–27 assignment system.
Bilingual and dual-language services create placements at selected schools according to home language, student need, and capacity. After eighth grade, students enter independently governed high-school districts. For the present school year, the active District 21 map and current language-service criteria remain the two controlling sources for K–8 placement.
