Summary:
Zip code 67050 has two schools in the Renwick district: Garden Plain Elementary, serving prekindergarten through 8th grade with 445 students, and Garden Plain High, serving grades 9–12 with 174 students. Their equal-weight average proficiency rates are above the state’s in all three subjects, by 10 points in ELA, 9 in math, and 10 in science. The clearest difference is math: Elementary is well above the state across grades 3–8, while High’s 10th-grade result is essentially level with the state, less than 1 point below.
Garden Plain Elementary leads the pair in all-grades results for 2025–26, ahead of High by 10 points in ELA, 27 in math, and 2 in science. Its grade-level results are consistently strong in ELA and math: across grades 3–8, it averages 14 points above the state in ELA and 21 points above in math. Garden Plain High stands out in 10th-grade ELA, 10 points above the state, and 11th-grade science, 17 points above. Its all-grades math figure is 5 points below the state, though the grade-matched 10th-grade result is nearly even. High also reports a 98% graduation rate versus 90% statewide and 3% chronic absenteeism versus 18% statewide. SchoolDigger gives both schools four stars: Elementary ranks 114th of 657 statewide and High 67th of 340.
Recent results show a notable math setback at High: its proficiency rate fell 18 points from 2024–25 to 2025–26, while Elementary’s fell 3 points and the state’s rose 2. As a result, the equal-weight two-school math average dropped from 60% to 50%, and its advantage over the state narrowed from 21 points to 9. High’s ELA moved in the opposite direction, rising 8 points while the state rose 1. SchoolDigger’s percentile histories also differ: Elementary moved from the 85th percentile to the 92nd, then the 83rd; High rose from the 66th to the 80th and stayed there. Reported free- or reduced-price lunch rates are similar—about 15% at each school—and offer context, not an explanation for results. Because the schools serve different grades, their all-grades results are not same-grade comparisons, and the two-school averages weight each school equally.
