Reading is more variable — it spiked to 66.77% in 2024–2025 before falling to 47.9% in 2025–2026, just under the state average — so it is worth watching. Several student groups, including students in special education, students from low-income families, and Hispanic students, rank above the state median.
Compared with nearby Monticello Senior High, Buffalo has a higher graduation rate (96.7% vs. 90.8%), a lower dropout rate (1.5% vs. 4.5%), and higher 2025–2026 proficiency in math (51.6% vs. 34.8%), reading (47.9% vs. 38.6%), and science (37.6% vs. 34.1%), though its student-teacher ratio is higher (23.7 vs. 20.4). Smaller nearby alternative programs such as Phoenix Learning Center, Wright Technical Center Alternative Learning Center, and Terra Nova School serve different student populations and generally report much lower graduation rates, so they are not direct academic comparisons. Many of their test results are suppressed, and suppressed values are unknown, not zero.
