Summary:
The 13 schools in De Soto include seven elementary schools, three middle schools and three high schools; 12 have reported 2025–26 test scores, while the Virtual Education Program does not. On average, each school type scored above the state in all three subjects, but the advantage was much larger in elementary and middle school than in high school. The most important takeaway is that results vary considerably between schools, especially among elementary schools.
Mize Elementary School leads elementary schools in ELA, math and science, with scores of 76%, 74% and 81%; it is ahead of Starside Elementary, which ranks lowest in all three, by 16, 32 and 36 percentage points, respectively. Starside’s math score of 42% is just 1 point above the state figure. Among middle schools, Lexington Trails Middle School leads in ELA and science, while Monticello Trails Middle School leads in math; Mill Creek Middle School is lowest in all three. Mill Valley High School outscores De Soto High School in every subject, by 4 points in ELA, 13 in math and 6 in science.
Recent changes are mixed: average ELA scores rose 3 points across schools with results in both years, compared with a 1-point state increase; average math rose less than 1 point, versus 2 statewide. Science scores rose an average of 9 points, while the state score fell 3. SchoolDigger rankings offer another perspective: Mize ranked 14th among Kansas elementary schools, and Mill Valley ranked 35th among high schools in 2025–26. Over three years, SchoolDigger’s percentile for Starside rose 24 points, while De Soto High fell 15. School context also differs: Starside’s student–teacher ratio is 10.9 and its free/reduced-lunch rate is 52%, compared with 12.1 and 7% at Mize; these figures describe the schools but do not explain their score differences.
