I am dealing with this now. All but 2 states have religious exempltions. Many have philosophical exemption. You just write an affidavit stating that it's against your religious beliefs and submit it in place of medical form. And no, they won't take it - federal goverment makes sure to brainwash schools into believing there are no exemptions (except for medical). So what I did is send it certified mail return receipt requested. (Actually I attached it to another affidavit stating that I did not withdraw her from school so I can't be accused of child neglect, but either way). Next few weeks will be interesting
