In MI they can't play up except for two circumstances.
1. If the student will be 19 before Sept 1 of their senior year then they may play as a freshman when they are an 8th grader so they will get in their four years of high school sports
2. Unless the rule has changed the state allowed 8th graders to play on a high school team if the total enrollment of the high school was less than 100 students. Again, this may have changed but I know at one time it was allowed by the MHSAA.
**on a side note, right now homeschooled students may not participate with the schools athletic teams in their district and the transfer rules can be pretty tough and are getting tougher. Good or bad, Michigan is pretty strict on a lot of these things.
