your kids ahould have to pass the same exit exams that kids in private or public schools must pass Give me one good reason you believe this...who is served by this?...not the kids, not the parents...think it through...
Do you actually believe that you would accomplish one single constructive thing by doing this?
So....should your homeschooled kids have to take SATs to get into college, or should they just be let in because you say they can do the work? What's next? Homeschool universities?
