Summary:
Glencoe, Oklahoma, has two schools: Glencoe Elementary School, serving prekindergarten through grade 8, and Glencoe High School, serving grades 9–12. The clearest takeaway is that the schools’ strongest subjects differ: the elementary school stands out in mathematics and science, while the high school stands out in English Language Arts I (ELA I).
Glencoe Elementary School had the highest reported 2025–2026 all-grades proficiency in mathematics, at 45% versus 25% statewide, and science, at 65% versus 30% statewide. Its science result was 46 points above the high school’s 19%; in mathematics, it was 26 points higher. The high school led in ELA I, with 44% proficiency compared with the elementary school’s 33%, and was 18 points above the state rate. The high school’s results were more mixed: it was 6 points below the state in mathematics, 11 points below in science, and matched the state in U.S. History. These all-grades comparisons cover different grade spans, so they are not like-grade rankings.
Results improved in several areas but not across the board: elementary science rose 31 points and mathematics rose 7, while ELA I fell 9; high school ELA I rose 16 points, mathematics 15, and science 3, while U.S. History fell 7. SchoolDigger’s high-school ranking moved from 296 of 463 schools (36th percentile, 2 stars) in 2024–2025 to 143 of 462 (69th percentile, 3 stars) in 2025–2026. For context, 2024–2025 student-teacher ratios were 17.5 at the elementary school and 12.8 at the high school. Both reported a free/reduced lunch eligible measure for 2024–2025: 72% at the elementary school and 63% at the high school; these are context, not explanations for results.
