Summary:
The 66207 list includes five Shawnee Mission public schools: three elementary schools, one middle school and one high school. The elementary schools average 76% proficiency in English language arts (ELA), 73% in math and 68% in science, compared with Kansas averages of 46%, 41% and 38%. Their average advantages are 30, 32 and 30 percentage points, respectively. The most important finding is that the area’s elementary schools are well above state results across all three subjects.
Trailwood Elementary stands out among the elementary schools, leading in ELA, math and science at 83%, 79% and 76%; its leads over the next-highest school are 10, 8 and 7 points. SchoolDigger ranks Trailwood 6th of 657 Kansas elementary schools and gives it five stars. Results vary among the other elementary schools: Briarwood Elementary has the lowest elementary science result at 58%, while John Diemer Elementary has the lowest elementary math result at 67%. Indian Woods Middle is above state results by 13 points in ELA and 22 points in both math and science. At Shawnee Mission South High, ELA and math are above state results by 8 and 10 points, while all-grades science is 5 points below; the 11th-grade science result is 3 points above the state result.
Recent elementary trends are mostly positive in ELA and math, but science differs by school. From 2024–25 to 2025–26, the elementary average rose 2 points in ELA and 4 in math; Diemer’s gains were 7 points in ELA and 5 in math. The average science result fell 2 points, as Trailwood dropped 7 while Briarwood rose 5. Diemer’s SchoolDigger rank improved from 120th to 46th, while Briarwood moved from 14th to 41st and remains a five-star school. Context also varies: lunch-program rates are 15% at Trailwood and 16% at Briarwood, compared with 31% at Diemer; South’s chronic absenteeism is 28%, versus 5%–7% at the elementary schools. These are observations, not explanations for test results. Because the schools serve different grade levels, comparisons between them are most useful within the same school level or subject and grade.
