Summary:
Whiteside School District 115 serves 1,155 students at two schools: Whiteside Elementary School (pre-K–4) and Whiteside Middle School (grades 5–8). The schools have different strengths, but mathematics is the clearest shared challenge: their equal-weight average is 24% proficient, 16 percentage points below the state’s 40%; in ELA, the average is 44%, 13 points below the state’s 56%.
Neither school leads in both subjects. Whiteside Middle leads in all-grades ELA, with 46% proficient compared with 41% at Whiteside Elementary; both are below the state, by 10 and 16 points, respectively. Elementary leads in mathematics, at 30% versus 18% at Middle, though those results are 10 and 22 points below the state. The strongest grade-level result is Middle’s fifth-grade ELA: 54%, just 1 point below the state. Its seventh-grade ELA is the sharpest shortfall, at 38%, 20 points below the state. Middle’s mathematics results are below the state in every reported grade, by 15 to 23 points.
Recent changes are mixed: Elementary mathematics fell 5 points from 2024–2025 to 2025–2026 while the state rose 1 point, widening the school’s gap from 3 to 10 points. Middle ELA rose 2 points and its mathematics score was unchanged. Middle science improved more strongly, gaining 12 points in fifth grade and 14 in eighth grade, though the latest results remain 9 and 7 points below the state. SchoolDigger’s rankings also moved down: Elementary went from the 46th to the 20th percentile and Middle from the 36th to the 17th percentile over the three reported years. As context, in 2024–2025, 63% of Elementary students and 56% of Middle students were free/reduced lunch eligible; student-teacher ratios were 14.1 and 16.3, respectively. These are observations, not explanations for the differences in scores.
