About this ranking
Schools are ranked by the percentage of students who scored at or above the ISASP % Proficient threshold on the latest available ISASP Mathematics test (school year 2024-25). A higher percentage is better.
Only public schools with a reasonable cohort size are included (at least 50 total students enrolled, since the source file does not include per-subject student counts), so very small programs and special-purpose centers are filtered out.
The state average shown above is enrollment-weighted: we multiply each school's score by how many of its students tested, sum those across every public school in Iowa, and divide by the total students tested. This way a big school counts more than a tiny one in the typical-student average.
