Original Research by School Decision on Yorkville Grade School
Yorkville Grade School serves children from preschool through third grade in Yorkville, a mixed-use riverfront city about 45 to 60 miles southwest of Chicago in Kendall County. The school enrolls a small enrollment typical for an early-grades building, with roughly even cohorts across the grade bands and a student body that is approximately half white, with meaningful shares of Hispanic and Asian students, along with smaller numbers of Black students. The racial composition mirrors broader Kendall County demographic patterns.
The school's academic pathway is limited by its grade span. Third grade is the only year the state tests students, so test results exist only at that level. In reading, third-grade proficiency sits in the lower range, with fewer than half the students meeting state standard. Mathematics performance is considerably stronger, with about two-thirds of third graders proficient. Participation in both tests was very high, near universal. When comparing this school to other public school buildings in Kendall County, overall proficiency ranks above the county midpoint, though this reflects a single grade and subject band and cannot be generalized across the full student career.
The measured data does not include free-or-reduced-price lunch figures, special education rates, or English learner enrollments, so those dimensions of family circumstance and support are not available here. Staffing, curriculum details, and program breadth are also absent from the record. Discipline, attendance, and other operational metrics were not provided.
The school sits in a fast-growing exurban county where housing values have risen and suburban development is accelerating. Yorkville itself combines a walkable historic downtown along the Fox River with auto-oriented retail corridors and newer residential subdivisions spreading westward from the Chicago region. The community is anchored by civic institutions like the courthouse and library, but serves primarily as a bedroom suburb with big-box retail and service employment.
The school's parent district, Yorkville CUSD 115, faces a significant unresolved crisis. Enrollment has tripled over the past decade, with more students projected. In March 2026, voters rejected a major bond referendum by a substantial margin that would have built two new schools and expanded the high school. The district is preparing a downsized proposal for November 2026, leaving capital infrastructure and tax questions unsettled. Classroom crowding is documented as real. The district has also implemented a new grading and learning plan as of 2024-25, shifting grades away from behavioral factors toward mastery of standards and introducing final exams in high school courses. Families considering this school should understand they are entering a district managing rapid growth with deferred facility needs and operating within a new academic framework.
A parent may want to look into the district's specific support for early grades during this period of transition and confirm what instructional materials and space constraints exist at this particular building.
