Summary:
ZIP code 67642 has two schools in Graham County: Hill City Elementary, serving prekindergarten through grade 6, and Hill City Junior-Senior High, serving grades 7–12; together, they enroll 383 students. The clearest difference is that the elementary school’s all-grades proficiency is substantially higher, while the high school’s results are below or near state figures.
Hill City Elementary stands out, with 2025–2026 proficiency of 70% in ELA, 56% in math, and 58% in science—24, 15, and 20 percentage points above the state, respectively. Hill City Junior-Senior High has the lower all-grades results: 38% in ELA, 39% in math, and 38% in science, respectively 8 points below, 2 points below, and nearly even with the state. The schools’ figures differ by 32 points in ELA, 17 in math, and 20 in science, but they serve different grade bands, so these are not same-grade comparisons.
Both schools improved in all three subjects from the prior year: elementary gains were 12 points in ELA, 4 in math, and 13 in science; high-school gains were 10, 2, and 12 points. SchoolDigger’s elementary ranking rose from the 58th percentile in 2023–2024 to the 83rd in 2025–2026, while the high school moved from the 58th to the 39th and back to the 58th percentile. Grade-level results add nuance: the high school was above the state in grade 8 math by 8 points and grade 11 science by 7 points. Chronic absenteeism was 4% at the elementary school and 20% at the high school, compared with 18% statewide. The elementary school also had a higher reported free/reduced-lunch rate (67% versus 45%) and student-teacher ratio (10.6 versus 8.9); these describe different school profiles, not reasons for their results.
