Summary

Sulphur High School serves 460 students in grades 9–12 in Sulphur, Oklahoma. Its latest graduation rate is the most concerning result: 74% in 2024–2025, the lowest among six nearby comprehensive high schools with reported rates and 15 points below the nearby-school average.

Academically, the school’s clearest advantage is mathematics: 32% of students were proficient in 2025–2026, the highest result among seven nearby schools and above the state’s 25% and the Sulphur district’s 26%. English Language Arts I was another relative strength at 40%, above the state’s 26% and district’s 25%, and tied for second among nearby schools.
