Students' performance on these statewide assessments can be used as one of multiple criteria to determine grade promotion or retention. To graduate, students will have to pass the MCA-II writing test given in grade nine (beginning in spring 2007), the MCA-II reading test given in grade ten (beginning in spring 2008), and the MCA-II math test given in grade 11 (beginning in spring 2009). All public schools and charter schools must administer the tests. Students must pass these required state exams, must successfully complete a required number of course credits, and must meet any local graduation requirements to graduate from a Minnesota public high school.
