Summary

Union Hill Elementary is a K–6 school in Grass Valley, California, with 542 students. Its latest schoolwide results are mixed: math is slightly above the state, while English language arts (ELA) and science are below. Attendance is a bright spot, with chronic absenteeism at 8% in 2025–2026, compared with 18% statewide. The clearest academic takeaway is the sharp difference by grade: third-grade math is a standout, while sixth-grade ELA and math are significant concerns.

Third-grade math proficiency was 66%, 19 percentage points above the state, and higher than the reported results at Alta Sierra Elementary (53%) and Bell Hill Academy (60%). In contrast, sixth-grade ELA was 28%, 21 points below the state and below results at Twin Ridges Home Study Charter, Grass Valley Charter and Chicago Park Elementary. Across all grades, ELA was 45%, 4 points below the state and close to the nearby-school average of 44%. Math was 40%, 1 point above the state but below the nearby average of 44%. Science was 31%, 5 points below the state but 2 above the Union Hill Elementary district; nearby results at Alta Sierra Elementary and Chicago Park Elementary were higher, at 55% and 73%.

Math has improved over time: it rose 4 points from 2022–2023 to 2025–2026 and moved from slightly below to 1 point above the state. ELA gained 2 points but fell further behind the state, while science declined by 1 point overall after a higher result in 2023–2024. Chronic absenteeism fell 27 points from 2021–2022. SchoolDigger ranks the school at the 54th percentile with 3 stars, close to the district’s 56th percentile and 3 stars. Its 2024–2025 student-teacher ratio was 20.2, near the nearby-school average of 19.6; 46% of students were free/reduced lunch eligible that year. A notable SchoolDigger subgroup result is its measure for Special Education Students: the school ranked at the 86th statewide percentile in 2025–2026, up from the 61st percentile in 2023–2024 and 32 points above its overall percentile. Nearby schools differ in grade spans, so all-grade comparisons are not perfectly like-for-like.
