Why can't you? These devices require accepting and agreeing to a EULA. Simply refuse the EULA and explain to the school administration that you will not enter into a contractual agreement with Apple or Google, nor will you allow them to defraud those companies by "accepting" the EULA for you.

Your child has a right to an education. School administrators cannot force parents to enter into contracts with companies as a condition for their child to receive an education.

For an extra solid case, insist that you have a sincere, deeply-held conviction against the use of these devices and any attempt to force their use or deny your child the right to an education due to your refusal is a violation of the First Amendment.

Why do parents just surrender and do whatever school admins want?
