I didn't homeschool, but I have heard from lots of parents who did homeschool to provide more challenge having to wash the egg off their face and take giant steps forward from time to time.

I think the MAP tests are generally very good, and I would encourage you to take them as a hypothesis and try them out. Maybe not to invest a lot until you've given a few things a try?

I wish I had an exact BTDT to share!
