With only one school in the area, there is no local school-to-school comparison; the clearest picture comes from comparing its results with Illinois and looking at changes over time. The most important finding is that mathematics is the school’s biggest challenge: in 2025–26, 20% of students were proficient overall, compared with 40% statewide—a 20-point gap.
Riverton is both the top and bottom school in this one-school list, so no local school stands out against another. Compared with the state, its strongest result is grade 8 ELA: 62% proficient versus 63% in Illinois, a 2-point shortfall. Its weakest is grade 6 math, at 15% versus 36%, or 21 points below the state. Overall ELA is closer to the state than math: 52% versus 56%, a 4-point gap. The math shortfall appears in every grade, ranging from 13 points in grade 8 to 21 points in grade 6.
