The Michigan Merit Exam (MME) is a replacement for the Michigan Educational Assessment Program (MEAP) test, a minimum-competency test for high school students. It was optional for class of 2007 (i.e., it could be taken instead of the MEAP) but was required for the class of 2008 and beyond. The MME is used to measure "Adequate yearly progress" as required under the No Child Left Behind Act.
Part of the MME is the ACT. In addition, there are Michigan-specific sections, including one on social studies, a essay-writing portions, and the WorkKeys test.
