Oak Grove Elem School, Libertyville IL

Original Research by School Decision on Oak Grove Elem School

Oak Grove Elementary School is a kindergarten-through-eighth-grade school in Libertyville, Illinois, serving a school community of roughly mid-size enrollment in an affluent residential area. The school sits within Oak Grove SD 68 Green Oaks, a single-school district.

The school's test performance, measured by the Illinois Assessment of Readiness, shows strength in elementary grades and variation in the middle grades. In third and fifth grades, proficiency runs strong across both math and reading. By fourth grade, math proficiency dips noticeably below the upper elementary range, while reading stays higher. Sixth grade shows the most visible challenge: math proficiency falls to roughly mid-range, while reading proficiency remains solid. Seventh grade rebounds sharply in reading to among the school's highest marks, though math stays in the upper-middle range. Eighth grade rounds out with reading and math proficiency both in the high seventies. Science proficiency, measured in fifth and eighth grades, shows strong results. Test participation is consistently high across grades.

When placed against Lake County school districts, Oak Grove's overall proficiency index sits in the top quartile, reflecting solid aggregate performance across tested subjects and grades.

The student body is predominantly white, with a substantial Asian population making up roughly a quarter of enrollment. Hispanic and multiracial students together form roughly one in seven students. The school reports no students identified as Native Hawaiian or Pacific Islander. Data on free-or-reduced-price lunch eligibility, special education enrollment, and English learner enrollment were not available.

Libertyville itself is a built-out residential village roughly a half-hour north of Chicago in central Lake County, with a historic downtown anchored by Cook Park and the Cook Memorial Library along Milwaukee Avenue. The downtown core, served by a Metra commuter rail station, is highly walkable and hosts regular farmers markets and community events, though the broader village is more car-oriented. Advocate Condell Medical Center, a major regional hospital, and Hollister Incorporated, a medical-products firm, are among the area's largest employers. Housing values in the area are above state averages and have appreciated in the past year. Rents are moderate relative to home prices, and rental costs consume roughly one-third of median household income.

The village is pursuing growth through incremental redevelopment rather than expansion, with recent approvals for multifamily housing, senior apartments, and a new municipal police station. The Metra station underwent renovation in the preceding years, and the village has adopted zoning plans for transit-oriented and corridor-focused development.

No recent district-level referendums, tax shifts, or curriculum overhauls meeting a lasting-impact threshold were confirmed in public sources. The district operates literacy program pilots and TAG program updates tracked in internal newsletters, but these do not carry the scale of change that a parent moving into or within the district would typically research as a deciding factor.

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.
