The Michigan Department of Education sets standardized testing schedules for Michigan students and schools.
From MDE's website:
"The 2014-15 and 2015-16 school years will bring substantial change in state required summative assessments.
In June of 2014, legislation was passed requiring the Michigan Department of Education (MDE) to develop a new summative assessment for use in Spring 2015. Unlike the previous MEAP assessments, the new assessment will be aligned to Michigan standards, administered in the spring, and measure current year versus past year student knowledge. English language arts and mathematics will be assessed in grades 3-8 and 11. Science will be assessed in grades 4, 7, and 11; and social studies in grades 5, 8, and 11. This assessment will be administered for one year, online with a paper and pencil option for schools not technology-ready.
The legislation also requires the department issue a Request For Proposal by September 1, 2014 for a new summative assessment system to begin in the 2015-16 school year."
