Keystone

Keystone has one elementary school, Keystone Public School, serving prekindergarten through eighth grade with 276 students. Its 2025–2026 results show different strengths by subject, rather than a consistent pattern across the board. The clearest strength is mathematics: the school’s all-grades proficiency was 40%, 15 percentage points above Oklahoma’s 25%.

There is no top or bottom school to compare within Keystone because the area has only one school; compared with the state, Keystone was below average in all-grades ELA and science, at 21% versus 26% in ELA and 28% versus 30% in science. Grade-specific results reveal a sharper contrast in ELA: third grade was 10%, 16 points below the state, while fourth grade was 31%, 9 points above it. Math was above state results in both reported grades: third grade was 47% versus 33%, and fourth grade was 50% versus 33%. Chronic absenteeism was also lower than the state rate in 2025–2026: 11% compared with 16%.

Overall results changed little from 2024–2025 to 2025–2026: ELA declined 1 point, from 22% to 21%; math declined 2 points, from 42% to 40%; and science stayed at 28%. The school’s math advantage over the state narrowed by 1 point, from 16 to 15 points, while its ELA gap widened from 4 to 5 points. SchoolDigger ranked the school at the 67th percentile and gave it 3 stars in 2025–2026, compared with the 68th percentile in 2024–2025 and 59th in 2023–2024. The student-teacher ratio was 11.5 in 2024–2025, and 72% of students were free/reduced lunch eligible that year. Since Keystone has just one school, these figures cannot show how schools vary within the area.
