Summary:
ZIP code 73834 has two schools: Buffalo Elementary School, serving prekindergarten through grade 8, and Buffalo High School, serving grades 9–12. The most important takeaway is that reported proficiency differs sharply between the schools, especially in math and science, so the elementary results do not describe what families should expect at the high school.
Buffalo Elementary stands out among the two schools in all three subjects they share: in 2025–2026, it had 23% proficiency in ELA, 26% in math and 32% in science, compared with 21%, 11% and 13% at Buffalo High. The elementary school’s leads were 2, 15 and 19 percentage points, respectively. It was near or above state results in those subjects, while the high school was below the state in every reported subject; its grade 11 results were 6 to 20 points below state results. The high school’s notable strength is graduation: its 2024–2025 rate was 95%, compared with 78% statewide, a 17-point advantage. The schools serve different grades, so these results are not a same-grade comparison.
Recent changes offer a mixed picture: Buffalo High improved in ELA, from 6% to 21%, and math, from 6% to 11%, between 2024–2025 and 2025–2026, but science slipped from 14% to 13%. Buffalo Elementary gained 2 points in math, while ELA fell 3 points and science fell 1. Across the six shared school-subject results, the average rose from 18% to 21%, while the state benchmark average remained 27%. SchoolDigger’s high-school percentile rank also improved, from 1 in 2023–2024 to 18 in 2025–2026; its elementary entries range from 20 in 2010–2011 to 72 in 2020–2021. As context, 2024–2025 free/reduced-lunch eligible shares were 57% at the elementary school and 53% at the high school; student-teacher ratios were 11.5 and 12.5, respectively.
