The APR score is the share of possible points a school earned under the Missouri School Improvement Program (MSIP 6), covering test performance, growth, attendance and, for high schools, graduation and college and career readiness. DESE compares these scores year over year in its 2025 release.
Note: this building has no state English or math test results in the 2025 report, so its APR score is based on fewer measures (8 points possible) and is not directly comparable with tested schools.
