<p>The idea is mandating all teachers to be certified, whether in public or private schools or while homeschooling. I’m not sure how CA teacher certification works. In some states, all prospective teachers need to do is take a pretty basic test. That shouldn’t cause all that much fall-out; hopefully, all teachers who have been teaching without being certified (including parents) would be able to pass such a test. If teacher certification actually involves getting a degree of some sort, then that’s a different matter that would keep many children from being homeschooled and many longtime teachers in private schools from remaining in the classroom.</p>
