Mossville Jr High, Mossville IL - Test Scores & Data

Original Research by School Decision on Mossville Jr High

Mossville Junior High is a small middle school serving grades six through eight in an unincorporated valley community between Peoria and Chillicothe in Peoria County, Illinois. The school enrolls roughly mid-sized cohorts across its grade band, with a student body that is predominantly white and drawn from the surrounding residential subdivisions and the local Caterpillar Technical Center campus area.

The school's test results show mixed performance across Illinois Assessment of Readiness and Illinois Science Assessment tests. In English language arts, sixth-grade proficiency runs solidly above half, while seventh and eighth grades cluster in the low-to-mid range. Mathematics proficiency is more uneven: sixth grade sits just below half, seventh grade improves, but eighth grade drops to the lowest point in that subject. Eighth-grade science proficiency sits just above half. Participation rates across the assessments are strong, running near universal participation. The school's overall proficiency index places it above the midpoint among Peoria County's school districts in tested subjects and grades, suggesting performance roughly in line with the county median, though individual grade-subject pairings show considerable variation. A parent may want to discuss with the school what specific supports are in place for eighth-grade mathematics, where performance dips noticeably.

The immediate locale is car-dependent and low-density, without a walkable town center or fixed-route public transit. Mail delivery routes through neighboring Chillicothe and Dunlap rather than a Mossville post office underline the community's dispersed, residential character. Caterpillar's Technical Center dominates the economic landscape and has shaped the area's character since the 1960s, though the company announced manufacturing-footprint reductions in recent years. Housing in the broader Peoria County market is relatively affordable and has appreciated modestly, with home prices a good bit lower than state and national benchmarks. The county market shows active inventory and steady demand, which may be relevant for families considering a move to the area.

State assessment data for grades below grade six were not available; the school serves only middle grades, which fall outside the full state testing span. No data on free-or-reduced-price lunch eligibility, English learner status, special education enrollment, or graduation rate appear in the available records, which is typical for a school that serves only grades six through eight. The district brief turned up no recent referendums, policy shifts, or curriculum changes meeting the threshold for parent awareness, suggesting relative stability in district operations. The school's website or district office would be a good source for program offerings, after-school activities, course sequences, and other details not covered in this assessment data.

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.
