Best Public Schools in Zip Code 62271

Zip code 62271 has two public schools: Okawville Grade School serves prekindergarten through grade 6 and enrolls 297 students, while Okawville Junior/Senior High School serves grades 7–12 and enrolls 224. Their 2025–26 results show different strengths: the Grade School is strong in several elementary grades, while the high school’s results vary between its middle-grade tests and later-grade assessments. Since the schools serve different grades, their overall IAR results are not direct head-to-head comparisons. The most important takeaway is that neither school’s overall score alone captures its full picture: grade-level and assessment results differ substantially.

The Grade School stands out in elementary results: its all-grades IAR proficiency was 62% in ELA and 59% in math, compared with state figures of 56% and 40%—advantages of 5 and 20 percentage points. Its strongest listed results were sixth-grade ELA, at 90% versus 59% statewide, and fourth-grade math, at 75% versus 42%. The high school’s grades 7–8 IAR results were below state levels, especially math: 28% overall versus 40%, an 11-point gap. Yet its 11th-grade ACT results were much stronger than state figures: 81% in ELA, 63% in math, and 84% in science, ahead by 31, 23, and 37 points. SchoolDigger rated the high school four stars and placed it at the 86th statewide percentile; the Grade School received three stars and ranked at the 69th percentile.

Recent IAR trends were mixed, with larger declines at the high school: from 2024–25 to 2025–26, the Grade School’s ELA fell 5 points while math rose 5; the high school’s ELA fell 11 points and math fell 7. SchoolDigger’s percentile ranking also dipped, by 9 points for the Grade School and 2 for the high school. Attendance is a relative strength: chronic absenteeism was 4% at the Grade School and 10% at the high school, versus 24% statewide. As context, both schools reported 25% free/reduced lunch eligible in 2024–25; student–teacher ratios were 13 at the Grade School and 11 at the high school. These measures describe the schools but do not explain their different results.
