Williamsville Jr High School, Williamsville IL

Original Research by School Decision on Williamsville Jr High School

Williamsville Jr High School serves fifth through eighth grade in a small central Illinois village, drawing from a community that straddles rural-residential character and growing suburban influence from nearby Springfield. The school enrolls around mid-sized numbers within its grade band, with enrollment split roughly evenly across the grades. The student body is predominantly white, reflecting the broader village demographics.

On state assessments, Williamsville Jr High shows a mixed profile across tested subjects and grades. In English language arts, the school performs stronger in the upper grades, with proficiency rising into the low-to-mid range by eighth grade. Math proficiency is more uneven. The school is strongest in sixth and eighth grade math and seventh grade English, where proficiency falls in the upper-mid range. Fifth grade math and seventh grade math are noticeably softer areas, closer to half of students meeting proficiency. Science shows similar ground. The school's overall proficiency index positions it in the top quartile among Sangamon County districts, a meaningful distinction that reflects relative strength within the regional context. State assessment data for third and fourth grade is not available; this appears to reflect that those grades are not tested under Illinois's assessment program. Participation rates in tested grades are high, generally above ninety-five percent, suggesting testing was conducted and data collection was solid.

The district recently passed a substantial bond referendum to restructure the school from a 6-8 to a 5-8 facility, with a new fifth grade wing now under construction to accommodate growing enrollment. This is a visible change in school size and grade composition. A parent considering enrollment or a family weighing a move into the area would want to clarify with the district the timeline and any interim arrangements for the fifth grade transition, as this represents both facility expansion and a shift in the school's operational structure. The renovation effort signals district investment in physical plant and growing enrollment pressure from the Springfield area.

Housing in the 62693 ZIP code is modestly valued and shows year-on-year appreciation. The Williamsville area offers a small-town setting with a compact downtown along historic Route 66, a community center and library clustered downtown, and tree-lined residential streets. Schools sit a few blocks south of the downtown core on Walnut Street. The village population has been relatively flat, though suburban growth from Springfield is visible in newer housing stock in the broader Sherman-Williamsville area. The locale has an agricultural economic base alongside small retail, a grain elevator, fertilizer supplier, and the school district as institutional anchors.

Whether this school is the right fit depends on family priorities around academic trajectory, school size, and community feel. The proficiency numbers warrant direct conversation with the school about support structures, curriculum changes, and any measures being taken to strengthen areas like seventh grade math. The bond-funded expansion offers a window into future facilities but also creates short-term operational questions. Parents seeking a small, tight-knit village school setting will find that here; those prioritizing schools with consistently high state assessment results across all grades may want to explore other options in the county.

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.
