Henry Winkelman Elem School, Glenview IL

Original Research by School Decision on Henry Winkelman Elem School

Henry Winkelman Elementary serves pre-kindergarten through fifth grade in Glenview, a prosperous North Shore suburb with two distinct commercial centers and strong civic institutions. The school enrolls a small-to-moderate-sized cohort with a notably diverse composition: roughly two-fifths of students identify as Asian, with additional representation of White, Hispanic, and multiracial families. A smaller share identify as Black or Native Hawaiian. Data on free-or-reduced-price lunch eligibility and on students receiving special education or English language instruction was not available.

The school's state testing results, from Illinois's most recent assessment administration, show a mixed picture across grade levels. In third-grade math and reading, students perform above the midpoint for schools in Cook County, with solid majorities meeting proficiency standards. By fourth grade, performance dips meaningfully in both subjects, dropping to roughly just above half. Fifth grade shows more uneven results: reading rebounds substantially, while math proficiency sits between the third and fourth-grade levels. Fifth-grade science proficiency, the only science data reported, reaches just above half. The school participates fully in state testing, with participation rates near or at full in all grades measured. Because the school serves pre-K through fifth grade and state testing begins in third grade, no results are reported for earlier or later grades by definition.

When positioned against other Cook County schools, Winkelman's overall proficiency index—a mean of performance across tested subjects and grades—places it in the top quartile. This reflects the strength of its third and fifth-grade English results and the decent baseline in early elementary math, even accounting for the fourth-grade dip. The combination suggests solid foundational instruction in younger years with room for continued support as students move into upper elementary.

The school's peer environment reflects Glenview's affluent, well-educated suburban character. The housing market in the area is active, with home values appreciating and sales moving relatively briskly. The district itself adopted a comprehensive strategic plan beginning in 2021, which now guides curriculum, calendar, and broader school programming decisions.

A parent may want to look into the school's approach to the fourth-grade transition in particular, where results decline noticeably in both core subjects. Understanding what support structures exist for students at that level—whether through small-group intervention, additional instruction time, or curricular adjustments—would help clarify whether this represents a known inflection point the school addresses deliberately or a gap worth exploring with staff.

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.
