Summary
Union 8th Grade Center is a grade-8-only middle school serving 1,100 students in Broken Arrow, Oklahoma. Its 2025–26 results show a mixed academic picture: math stands out locally, while English Language Arts I is its weakest subject compared with the state. The clearest takeaway is that math is a notable local strength, but ELA remains below the state result.
In eighth-grade math, the school scored 19%, matching the Union district and topping the state’s 17%; it had the highest score among seven nearby schools reporting results, whose other scores averaged 6%. ELA I was 16%, matching the district but 4 percentage points below the state’s 20%; the school ranked fourth among those seven nearby schools. Science was also 31%, matching the district but 5 points below the state. That result tied Oliver Middle School and was just below Centennial Middle School at 32%, and it was above the nearby-school average of 20%.
The school’s scores changed only modestly from 2024–25 to 2025–26: ELA I fell from 17% to 16%, math from 21% to 19%, and science rose from 30% to 31%. State comparisons across those years use different grade groupings, so they do not establish whether grade-specific gaps narrowed or widened. SchoolDigger rates the school at the 46th percentile, with 2 stars, in 2025–26; its percentile rose from 14 in 2022–23, reached 51 in 2024–25, then slipped 5 points. SchoolDigger’s statewide group ratings show a much stronger relative standing for White students (82nd percentile) than overall, while its rating for Native American students is at the 7th percentile, down 58 points from the prior year. These are comparative school ratings, not underlying student test scores. In 2024–25, the student-teacher ratio was 18.2, near the nearby-school average of 18.3, and 73% of students were free/reduced lunch eligible. Chronic absenteeism improved by 7 points to 24% in 2025–26, but remained above the district’s 22% and the state’s 16%.
