Summary:
ZIP code 66064 has two elementary schools in the Osawatomie district: Trojan Elementary, serving grades 1–5, and Swenson Early Childhood Education Center, serving pre-K–K. The clearest overall concern is that Trojan’s 2025–26 results were below state rates in all three reported subjects; averaged across ELA, math, and science, its result was 28% compared with 42% statewide, a 13-point gap.
Trojan’s relative strength is ELA, though it still trailed the state: 38% proficient versus 46%, while exceeding the district by 6 points. Its math and science results were farther behind the state—24% versus 41% in math, and 23% versus 38% in science. Fourth-grade ELA was a bright spot: 52% proficient, 2 points above the state; by contrast, fifth-grade science was 23 points below the state. Swenson had the lower chronic-absenteeism rate, at 14% versus Trojan’s 15%; both were below the state’s 18%. Swenson has no listed test scores, so an achievement comparison between the schools isn’t possible.
Trojan’s scores fell from 2024–25 to 2025–26: by 2 points in ELA, 3 in math, and 7 in science, while the state’s ELA and math results rose. As a result, Trojan’s gaps with the state widened by about 4 points in ELA, 4 in math, and 3 in science. SchoolDigger’s ranking also declined, from the 25th percentile in 2023–24 to the 15th percentile in 2025–26. Other figures offer context rather than a basis for explaining results: Trojan’s student–teacher ratio was 11.7, compared with Swenson’s 13.2, and their free/reduced-lunch rates were 69% and 60%, respectively.
