Summary:
Zip code 49250 is home to just one elementary school, Williams Elementary School, which serves grades K-5 in the Jonesville Community Schools district, with 512 students and a moderate-to-high level of economic need (54.5% eligible for free/reduced lunch).
For parents considering this area, Williams Elementary is a school with clear strengths and some areas to watch. The most impressive statistic is its chronic absenteeism rate of just 11.6%—less than half the state average of 27.9%—which signals strong daily attendance and a positive school culture. Academically, the school shows a notable bright spot in 5th-grade science, where proficiency reached 56.6% in the 2024-2025 school year, well above the state average of 40.3%. However, more recent 2025-2026 data shows a dip in that subject to 35.6%, and reading and math scores are mixed: 3rd-grade math (45.8%) beats the state average, but 4th and 5th-grade math, along with all ELA grades, fall below state averages. The school also demonstrates significant grade-level swings—for example, 3rd-grade math proficiency was 58% in 2024-2025 but dropped to 27.6% by 5th grade, suggesting the school may excel in early grades but struggles to sustain momentum.
One interesting contradiction is that the school’s overall state ranking has improved over three years (from the 41st to the 60th percentile in 2023-2024), yet its most recent proficiency scores are mostly below state averages—this may reflect a different cohort of students or a ranking that factors in growth. With per-student spending of $14,592 and a low student-teacher ratio of 15.1, the school is well-resourced, though those resources haven’t yet produced consistently above-average test results across all subjects. The district itself is ranked in the middle of Michigan (49th percentile, 2-star rating). For parents, this is a school with excellent attendance, strong early-grade math, and a standout science program, but one where reading proficiency and upper-grade performance will require attention.
