Why It Matters

Missouri Assessment Program (MAP) tests are scored (or graded) according to four achievement levels: Below Basic, Basic, Proficient, and Advanced. The number shown here is the percentage of students who scored Proficient or Advanced. When comparing scores between years, please remember that the test Missouri gives has changed several times.

Please note that private schools are not required to participate in these exams.

In 2019, the average English score in Missouri was 48.7%; the average Math score was 41.9%, source

Attendance Rate 90/90


Why It Matters

Schools strive to have at least 90% of their students achieve a 90% attendance rate because kids learn best when they’re in school.

In 2019, 87.3% of Missouri students were in attendance at least 90% of the time, source.
