What this means: About 39% of students here test proficient in math and reading, compared with the roughly 47% typical for Missouri schools with a similar share of low-income students. BeatsExpectations measures results against demographically similar schools rather than by raw scores, and this school falls within the typical range, neither among Missouri's top nor bottom 10%.

BeatsExpectations runs a per-state regression of proficiency on free/reduced-lunch share, then scores each school by residual. How this is calculated →

How to read these scores

What is MAP?
The Missouri Assessment Program (MAP) is Missouri's annual statewide test. Public-school students in grades 3 through 8 take MAP Grade-Level Assessments in English Language Arts and Math each spring, with Science added at grades 5 and 8. High school students take End-of-Course (EOC) exams, including English II, Algebra I, Biology, and Government.
What does "% Proficient + Advanced" mean?
It is the percentage of students at the school who scored "Proficient" or "Advanced" on MAP, the top 2 of 4 performance levels (Below Basic, Basic, Proficient, Advanced). Proficient and above is Missouri's grade-level bar. A higher number is better.
What does 45.9% mean for English Language Arts at OSAGE HIGH?
It means about 45.9 percent of students tested at OSAGE HIGH performed at grade level or above on the MAP English Language Arts test in 2024-25. The statewide average for Missouri that year was 44.9%. The other students fell into the lower performance levels.
How is the state average calculated?
It is a weighted average, not a simple average of each school's number. We multiply each public school's score by how many of its students tested, add those together for all schools in Missouri, and divide by the total students tested that year. This way a big school with 1,500 students counts more than a small school with 50 students, which is the right way to ask "how did the typical student do this year?". District and county averages on this page use the same method, just scoped to that district or county.
Where does this data come from?
Missouri Department of Elementary and Secondary Education (DESE), Missouri Assessment Program (MAP) Grade-Level and End-of-Course assessments. School-level file from the Missouri Comprehensive Data System (MCDS), as republished without a login by the Missouri Education Data Explorer (moschooldata.org). All Students group; "All grades" is DESE's own all-grades figure, and the high school row is the English II, Algebra I, Biology, or Government end-of-course exam. Headline metric is the share of students scoring Proficient or Advanced (top 2 of 4 MAP levels). DESE leaves a cell blank when a group is too small to report. Growth figures come from DESE's Missouri Growth Model (SAS EVAAS, Missouri Data Visualization Tool).
How often is it updated?
MAP is administered once a year (spring). Results are released by the state in the summer or early fall. We refresh this page after each annual release.
