Summary:
Zip code 74450 has one listed high school, Oktaha High School, serving grades 9–12 and enrolling 215 students. With no other local high school to compare, the clearest picture comes from its results against state figures. The most important finding is that in 2025–2026, Oktaha was above the state in three of four tested subjects, with science the exception.
Oktaha High School stands out for English Language Arts I, mathematics and U.S. History: its 2025–2026 all-grades proficiency rates were 41%, 33% and 47%, respectively, compared with 26%, 25% and 41% statewide. Science was its weakest subject at 20%, 10 points below the state’s 30%. Other reported measures are also favorable against state figures: the 2024–2025 graduation rate was 100% versus 78% statewide, and 2025–2026 chronic absenteeism was 1% versus 16% statewide.
Results improved in all four subjects from 2024–2025 to 2025–2026: English rose 9 points, mathematics 16, science 1 and U.S. History 10. The unweighted average across the four subjects increased from 26% to 35%, moving from about 5 points below the state average to about 5 points above; this is an average of subject rates, not an overall student proficiency rate. SchoolDigger’s statewide percentile ranking also rose from the 36th percentile in 2023–2024 to the 78th in 2025–2026. As context, the school reported 81% free/reduced lunch eligible in 2024–2025 and a student–teacher ratio of 13.7 in 2024–2025; those figures do not explain the school’s results.
