West Oak Middle School, Mundelein IL

Original Research by School Decision on West Oak Middle School

West Oak Middle School serves grades six through eight in Mundelein, in Lake County's Diamond Lake School District 76. The school's enrollment is small for a middle school, distributed roughly evenly across its three grade levels.

The student body is predominantly Hispanic, with a much smaller white population and smaller representation of Asian and multiracial students. The school is a regular public school, not a charter or magnet.

On state assessments, West Oak shows weak proficiency results. In English language arts, the school's performance ranges from lower proficiency in sixth grade (at the upper mid-range) up through eighth grade (approaching the low-to-mid range). Mathematics performance is notably lower: sixth and seventh graders show proficiency rates in the low range, while eighth graders are only slightly higher. In science, eighth-grade results sit in the low-to-mid range. Across tested subjects and grades, the school's overall proficiency sits in the bottom quartile relative to other districts in Lake County. Participation in testing is strong, with most cohorts approaching or exceeding near-universal participation, so absenteeism on testing days does not explain the results.

The state modified its proficiency standards in these subjects this year, so year-over-year trend comparison is not available. A parent may want to look into further with the school what specific supports are in place for students working toward proficiency in math, where the need appears most acute.

Mundelein itself is a mixed residential and industrial Lake County village anchored by Medline Industries, the country's largest privately held medical supplies manufacturer. The community has a downtown core near the Metra station with growing walkable retail and housing, but is otherwise auto-oriented. The village is in active growth, with new apartment communities, townhomes, and single-family subdivisions opening or under construction, plus a major long-range traditional neighborhood development on a former farm. Housing values in the broader Lake County market are rising modestly, and median rent is also rising slightly. The local labor market includes manufacturing, healthcare, and retail, with the unemployment rate steady.

School district information about curriculum changes or new programs was not available; the district does offer a K-5 dual-language program that predates recent years.

No data on free-or-reduced-price lunch eligibility, special education enrollment, English learner enrollment, graduation rate, attendance, or discipline were available for this school.

Graduation rate (ACGR) reflects the federally published Adjusted Cohort Graduation Rate for the most recent year available. We refresh this data annually at the close of each academic year in June. The federal source publishes a banded rate (for example, "90-94%") instead of an exact number for cohorts small enough to risk identifying individual students. The state distribution chart, where shown, plots every school in the state with a published rate or band; schools whose rate is federally suppressed are excluded. Where the federal source publishes a band rather than an exact rate, the school is placed within its band using a stable, ID-derived offset, so its position is consistent across visits.
