Summary:
ZIP code 62864 has eight schools—six elementary schools, one middle school and one high school—serving students from the early grades through grade 12, with results that vary widely across the area. Across the seven schools reporting all-grades IAR results, the average was 45% in ELA and 30% in math in 2025–2026, about 11 and 10 points below state results. Because schools serve different grade spans, all-grades results are not perfectly like-for-like comparisons. The most important takeaway is that these area averages hide large differences between individual schools.
Summersville Grade School is the clearest standout: its all-grades results were 66% in ELA and 53% in math, respectively 9 and 13 points above the state; in grade 8, it reached 97% in ELA and 74% in math, versus state results of 63% and 35%. McClellan Elementary School had the second-highest all-grades ELA result, 60%, though its 35% math result was below the state. At the lower end, Dr Nick Osborne Primary Center recorded 27% in all-grades ELA, 30 points below the state, while Zadok Casey Middle School had the lowest all-grades math result, 13%, 27 points below the state. Mount Vernon High School was also below state results on grade-11 ACT proficiency by 23 points in ELA, 21 in math and 21 in science.
Recent changes are mixed: the seven-school average rose by about 3 points in both ELA and math from 2024–2025 to 2025–2026, while McClellan improved 19 points in ELA and 16 in math; Summersville fell 2 points in ELA and 4 in math. SchoolDigger rankings also shifted: Summersville moved from the 74th to the 50th percentile and Zadok Casey from the 23rd to the 8th between 2023–2024 and 2025–2026. All eight schools report free/reduced lunch eligible for 2024–2025: the measure was 38% at Summersville and 45% at McClellan, compared with 92% at Osborne and 85% at J L Buford Intermediate Educational Center. These figures are context, not explanations for test results; enrollment and ratios differ too, from 56 students and an 8.3 student-teacher ratio at McClellan to 283 students and a 12.2 ratio at Summersville.
