School Messenger Opt-InParents, this summer the Knox County Schools will be requiring parents to opt-in to receive messages on your mobile device. If you would like to continue receiving messages from Career Magnet Academy concerning your child, please read the documents below. One the parent consent form, there are directions for how to handle this issue online, rather than sending them form in with your scholar. However, it is perfectly acceptable to send the form in by hand. Thank you for your attention to this issue!
