Estimated Math Instructional Level
Star Math normally starts a student's first test with questions slightly below the student's grade level. If the student has taken a Star Math test in the past six months, Star Math uses the results from the last test to decide the starting difficulty level for the next one.
However, when students have an Estimated Math Instructional Level (MIL) set, Star Math uses that level to decide how difficult the first question should be. You should only enter an Estimated MIL for students who receive math instruction at a higher or lower level than their current grade.
Although kindergarteners can take the Star Math test, kindergarten (K) cannot be set as a Math Instructional Level.
