Summary:
Grandfield, Oklahoma, has two schools and no separate middle school: Grandfield Elementary School serves prekindergarten through grade 8, and Grandfield High School serves grades 9–12. The latest results show different strengths by subject, with the elementary school ahead in math and the high school ahead in ELA; the most notable contrast is that the high school’s graduation rate is strong even though its latest proficiency results are below state results in every reported subject.
The elementary school stands out in 2025–2026 math, with 27% proficient compared with 15% at the high school and 25% statewide—12 points ahead of the high school and 2 points above the state. In ELA, the high school leads the elementary school, 20% to 15%, though both are below the 26% state result. The high school’s 2024–2025 graduation rate was 95%, compared with 78% statewide, a 17-point advantage. The elementary school also reported 48% proficient in 2024–2025 science, versus 16% at the high school and 30% statewide; these all-grades figures come from schools serving different grade spans, so they are not a like-for-like ranking.
Recent results are mixed: from 2024–2025 to 2025–2026, elementary math rose from 23% to 27% and ELA from 14% to 15%, while high-school math fell from 16% to 15% and ELA from 22% to 20%. Across the two schools, the math gap to the state narrowed from 7 points to 4, while the ELA gap widened from 8 to 9 points. SchoolDigger’s high-school rank improved from 356 of 463 schools in 2024–2025 to 336 of 462 in 2025–2026, after ranking 215 of 432 in 2023–2024. The elementary school has 142 students, a 15.3 student-teacher ratio, and 95% free/reduced lunch eligible in 2024–2025; the high school has 76 students, an 18.8 ratio, and 86% eligible that year.
