Original Research by School Decision on Old Quarry Middle Sch
Old Quarry Middle School serves grades six through eight in Lemont, a suburban village southwest of Chicago with a historic character anchored by a compact downtown along the I&M Canal and a surrounding base of single-family homes and newer subdivisions. The school draws from a community that has grown steadily in recent years, with a competitive housing market and ongoing development adding single-family homes, duplexes, and townhomes.
The school's student body is predominantly white, with smaller populations of Asian, Hispanic, and multiracial students. Free and reduced price lunch data was not available, so a reader cannot assess from this profile the share of students qualifying for economic assistance. Special education enrollment counts and English learner status were also not reported.
In state testing, Old Quarry shows uneven performance across its grade band. In English language arts, the school's proficiency rises with grade level: sixth graders show solid proficiency, seventh graders perform stronger, and eighth graders score substantially higher. Math proficiency tells a different story. Sixth grade math proficiency is respectable, but seventh grade proficiency dips noticeably, before rising again in eighth grade. Science results are available only for eighth grade, where proficiency is in the mid-range. The state testing data for grades three through five appear in the data sections but were not reported for this school, likely because Old Quarry serves middle grades only and those earlier grades are tested elsewhere. Participation in state assessments was complete or nearly complete across all tested grades.
When compared against other districts in Cook County, Old Quarry's overall proficiency index places it in the top quartile. This positioning reflects the school's stronger eighth-grade performance and solid sixth-grade showing in English language arts, even though seventh-grade math proficiency moderates the overall picture.
The school is a regular public school, not a charter or magnet, and sits within the Lemont-Bromberek Consolidated School District 113A. In 2021, the district passed a 29-cent operating rate increase referendum, its first operating tax increase in over four decades, which has funded reduced class sizes, added staff, and expanded programs. The district also reopened Central School in 2022-23 and launched full-day kindergarten district-wide, moves that signal ongoing investment in student support and program breadth at the elementary level.
Lemont itself is a mixed-use village with civic anchors including the Lemont Public Library, a Metra station on the Heritage Corridor line in the downtown, and proximity to parks and forest preserves such as Waterfall Glen and Red Gate Woods. Argonne National Laboratory is the region's largest employer. The housing market is competitive; homes in the area have appreciated and median home values reflect suburban Cook County pricing.
A parent may want to look into the school's seventh-grade math performance further with the district to understand what drives the dip and what support or intervention structures are in place. Staff counts, attendance data, discipline records, and detailed course offerings were not available in the provided data, so readers interested in those specifics should consult the school or district directly.
