Summary:
Janesville Union Elementary has one school, Janesville Elementary, serving kindergarten through grade 8, with 313 students. With no other local schools to compare, the key picture is how the school’s results compare with the state and differ by grade. In 2025–2026, all-grade results were below the state in ELA (46% versus 49%), math (33% versus 38%), and science (33% versus 36%); the clearest concern is fifth grade, which was below the state in all three subjects.
Within the school, seventh and eighth grades stand out positively, while fifth grade is the weakest point in the reported results. Seventh graders were above the state in ELA, 55% versus 51% (4 points), and math, 44% versus 38% (6 points). Eighth graders were also ahead in ELA, math, and science, by 2, 5, and 7 points, respectively. By contrast, fifth-grade results were 34% in ELA versus 49% statewide, 13% in math versus 37%, and 26% in science versus 35%—gaps of 15, 24, and 9 points. As the only school in the area, Janesville is technically both the local highest and lowest; the data cannot identify a school-to-school leader.
Results moved in different directions over time: from 2024–2025 to 2025–2026, ELA rose from 45% to 46% and science from 28% to 33%, while math fell from 37% to 33%. Math’s gap with the state widened by about 5 points, while the ELA and science gaps narrowed; the simple average gap across the three subjects shifted from about 3 points behind to about 4 points behind. SchoolDigger’s school percentile went from 32 in 2023–2024 to 52, then down to 44 in 2025–2026. Separately, SchoolDigger lists the district at rank 406 of 968, in the 58th percentile, with 3 stars. Other context: the student-teacher ratio was 18.3 in 2024–2025, and 51% of students were free/reduced lunch eligible that year. Chronic absenteeism was lower than the state’s in 2025–2026: 15% versus 18%, a 4-point difference.
