Summary:
Schools in ZIP code 74447 include five schools serving grades PK–12: three elementary schools, one middle school, and one high school, with individual grade spans ranging from PK–4 to PK–8 and grades 9–12. In 2025–2026, the schools’ average All Grades proficiency was 15% in ELA, 13% in math, and 18% in science, compared with 26%, 25%, and 30% statewide. The most important finding is how sharply results vary by school, especially in math and science.
Twin Hills Public School stands out in math and science, with 28% and 39% proficient—3 and 9 points above the state, and far ahead of the other reporting schools’ averages by 19 and 28 points. Its ELA result is 20%, however, 6 points below the state. Okmulgee Primary Elementary School leads ELA at 23%, while Dunbar Intermediate Elementary School is lowest in ELA and math at 7% and 4%. Okmulgee High School has the lowest math result, 2%, and its 9% science result is the lowest among schools reporting that subject.
Recent results show no consistent upward trend: the five-school ELA average fell 3 points, math rose 1 point, and the four-school science average was unchanged from 2024–2025. The largest decline was at Academy Of Okmulgee Elementary School, where science fell 18 points, from 31% to 13%; Twin Hills’ math and science rose 4 and 6 points even as its ELA fell 8. SchoolDigger ranks Twin Hills 305 of 626 (51st percentile, 3 stars), compared with Dunbar at 357 of 378 and Okmulgee High at 440 of 462 (both 0 stars). All five schools reported free/reduced lunch eligible shares for 2024–2025: Twin Hills was 69% and Academy 67%, yet their results differed considerably; these figures are context, not an explanation. Results also differ by grade, so a school’s overall figures may not reflect the experience in a particular grade.
