Summary:
The four schools in Silo serve students from prekindergarten through grade 12 and list a combined enrollment of 1,249. Test scores are available for the elementary, middle, and high schools, but not Silo Ecc. Across those three schools, the average proficiency results are below state averages in ELA, math, and science; science has the largest gap, though the middle school is a notable exception. The most important takeaway is that the area’s results vary sharply by subject: the average is below the state in all three, while Silo Middle School stands out in science.
The strongest results differ by subject, and the weakest school changes with it. In 2025–26 all-grades results, Silo Elementary School leads math at 32%, 7 percentage points above the state; Silo Middle School leads science at 42%, 12 points above the state; and Silo High School leads ELA at 31%, 5 points above the state. At the other end, High is at 14% in math and science, respectively 11 and 16 points below state results. The largest school-to-school spread is in science: Middle’s 42% is 28 points above High’s 14%. High also posts 44% proficiency in U.S. History, 3 points above the state.
Recent averages moved down in all three tested subjects: from 2024–25 to 2025–26, the unweighted three-school averages fell by 4 points in ELA, 2 in math, and 1 in science. ELA shifted from above the state average to below it, while math and science gaps widened slightly. SchoolDigger’s latest rankings place High at the 51st percentile with 3 stars, Elementary at the 45th with 2 stars, and Middle at the 43rd with 2 stars; since 2023–24, Elementary and High have risen 24 and 20 percentile points, while Middle has slipped 2. Class-size context also varies: Middle has the lowest student-teacher ratio at 12.5, compared with 16.0 at High. In 2024–25, the free/reduced lunch eligible share ranged from 50% at High to 71% at Silo Ecc; these figures are context, not an explanation for results. High’s graduation rate was 81%, matching the district and 3 points above the state.
