Michigan's school records are an excellent tool for genealogical research.  They allow you to place a person in a time period, sometimes names of parents and guardians can be obtained, and it allows you to round out a family member's history.

People have been donating materials and time to type data out for Michigan researchers and are included here.  The records in this area can be school censuses, records, yearbooks, and commencement programs, to name some.
