Sounds like the school is broken and needs to be fixed or replaced.
Best of luck.
School attended by my offspring has signed them all up for Google Drive (etc.) without even asking. Now they are expected to use it to complete assignments from home.
What a shame their main computer is a Pi which doesn't quite manage to make Drive work...
Then there's selling (presumably) my mobile phone number (again without asking - my number is on record purely for use as an emergency contact) to a commercial company which wants me to sign up to some kind of proprietary twitter-like thing so that the school can "keep in touch", something it could do just as effectively by other methods but has a pretty poor track record of doing so.
I could go on...
