It takes about 4 hours a day to homeschool

If you've ever wondered why the law only required 4 1/2 hours a day to homeschool, it is because that is pretty much how long it takes.  After homeschooling all the way through, my kids spent some days homeschooling for 8 hours, and other days not homeschooling at all, or going to outside classes.  They may have done more than an average of 4 hours a day, but they also accomplished a lot more than what is required of a typical student.

This video is specifically about black homeschoolers in Louisiana turning to homeschooling, but one of the teachers/parents makes it clear how much can be accomplished in a short amount of time.
