"Many go out on Twitter (there are no alternatives if you don't 'do' FB or Twitter, you must 'do' FB and Twitter or you are evil and should have your children removed from you)"
Why can't the school have their own website where they can post notices, class assignments, etc? I'll bet that most of the kids these days could design and run it for them as a class project for extra credit just like a school newspaper. Any changes would get held for review before going public. Anything to do with kid's information could behind a 2FA login that parents set during a school visit.
