Summary:
Altus has three middle schools serving 1,116 students: Altus Intermediate School serves grades 5–6, while Altus Junior High School and Navajo Junior High School serve grades 7–8. Because the schools cover different grades, all-grades comparisons don’t show how they perform with the same grade groups. The clearest shared strength is science: in 2025–2026, every school’s score was above the state’s 30%—by 5 to 21 percentage points.
The schools have different subject strengths, and the top and bottom scores vary by subject. In 2025–2026 all-grades results, Altus Intermediate led English Language Arts I at 31%, while Navajo had the lowest score at 24%, a 7-point spread; the state result was 26%. Altus Intermediate also led math at 32%, compared with Altus Junior High’s 20%, a 12-point spread; the state result was 25%. Navajo led science at 51%, while Altus Intermediate scored 35%, a 16-point spread; both were above the state result of 30%. These all-grades figures are useful for a broad overview, but same-grade results offer a fairer comparison.
Average results across the three schools improved from 2024–2025 to 2025–2026: ELA rose 3 percentage points, math 1 point, and science 9 points. Gains weren’t uniform: Navajo’s ELA rose 7 points and science 13 points, but its math fell 6 points. Navajo’s all-grades results also conceal a sharp grade-level contrast: its 7th graders scored 39% in ELA and 46% in math, while its 8th graders scored 8% and 10%. Altus Intermediate exceeded state results in both ELA and math in grades 5 and 6, by 4 to 6 points. As context, 2024–2025 student-teacher ratios were 18.3 at Altus Junior High, 17.5 at Altus Intermediate, and 14.2 at Navajo; the schools’ free/reduced lunch eligible shares that year were 68%, 68%, and 43%, respectively. SchoolDigger statewide ranking percentiles rose for the two schools with rank histories: Altus Junior High went from 54 in 2023–2024 to 64 in 2025–2026, and Navajo from 61 in 2018–2019 to 72 in 2025–2026; those rankings are not proficiency changes.
