Summary
F L Schlagle High is a Kansas City, Kansas, district high school serving 841 students in grades 9–12. In 2025–2026, only 7% of students were proficient in English language arts (ELA), 5% in math, and 4% in science; chronic absenteeism was 64%, compared with 39% in the Kansas City district and 18% statewide. The combination of very low proficiency and persistently high absenteeism is the school’s most important concern for families.
Schlagle is near the bottom among nearby Kansas City district high schools, though its standing varies by subject: it ranked second-lowest in ELA, third-lowest in math, and lowest in science among six schools. Its proficiency rates were also below district and state results in every subject: ELA was 7%, versus 23% districtwide and 46% statewide; math was 5%, versus 16% and 41%; and science was 4%, versus 15% and 38%. Sumner Academy of Arts & Science was far ahead of the other district schools, with 76% proficiency in ELA, 69% in math, and 50% in science.
Scores have risen from 2022–2023, but not enough to catch up with the state: ELA improved from 4% to 7%, math from 1% to 5%, and science from 2% to 4%, while the state gap widened in each subject. Attendance has stayed around 64% across the four reported years. SchoolDigger ranked Schlagle 337th of 340 Kansas schools, at the 1st percentile with 0 stars, in 2025–2026. Its student-teacher ratio was 16, not especially high among nearby comprehensive high schools; 74% of students received free or reduced-price lunch in 2024–2025. Graduation was a relative bright spot: the 2023–2024 rate was 80%, above the district’s 78% but below the state’s 90%. SchoolDigger’s subgroup rankings also changed sharply: its measure of how well the school serves English learners fell from the 84th percentile in 2024–2025 to the 21st in 2025–2026, while its special education ranking dropped from the 50th to the 6th percentile.
