Bristol Bay Elem Sch, Yorkville IL

Original Research by School Decision on Bristol Bay Elem Sch

Bristol Bay Elementary serves about a mid-sized enrollment across kindergarten through sixth grade in Yorkville, a fast-growing suburb in Kendall County southwest of Chicago. The school sits in a region experiencing significant residential expansion, with new townhome communities and subdivisions reshaping the area's character. Yorkville itself mixes a small historic downtown along the Fox River with newer commercial corridors and suburban residential patterns, though the city remains heavily car-dependent for getting around.

The school's academic results show mixed performance across tested grades. In third grade, math proficiency is above the midpoint for what the state tested; English language arts runs about a similar range. Fourth and fifth grades show steeper declines in math, with fifth grade science proficiency also below the midpoint. By sixth grade, English language arts improves notably, while math remains weaker. Performance across tested subjects and grades sits above the midpoint when compared to other districts in Kendall County, though the trajectory across upper elementary grades shows that math proficiency is a softer area.

The school's enrollment is roughly three-quarters white, with meaningful shares of Hispanic and Black students, plus smaller numbers of Asian and multiracial students. State testing data for free-or-reduced-price-lunch eligibility was not available, so a parent may want to ask the school directly about the share of students qualifying for these programs if that matters to their decision. English learner and special education enrollment counts were also not provided in the data, another detail worth checking with the school if those populations are relevant to your family.

Bristol Bay operates within Yorkville CUSD 115, a district in the midst of significant change. The district rejected a major bond referendum in March 2026 by a substantial margin, leaving an unresolved overcrowding crisis unaddressed. Enrollment has tripled over the past two decades, with further growth projected. A downsized referendum proposal is planned for November 2026, so the question of new facilities and tax increases remains in flux. For families considering a move to the area, this uncertainty around school capacity and infrastructure deserves attention.

The district has also implemented a new Learning and Grading Plan starting in 2024-25 that grades students on mastery of academic standards rather than behaviors like attendance and participation. Homework, effort, and attitude no longer factor into grades. Final exams or experiences will count for a portion of high school course grades. This represents a meaningful shift in how student achievement is measured and reported, one parents may want to understand fully as their children advance.

Housing in the Yorkville area has seen steady appreciation, with median home values modestly above state benchmarks and some increase year-over-year. Rental housing is available and carries costs in line with regional affordability. The community continues to attract families seeking newer suburban development with good schools, though the district's capacity strains and the failed referendum suggest that growth has outpaced infrastructure investment so far.

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.
