Not true, and also not possible.

If a kid or parent can log in from offsite, it is not technically possible to force all browsers or systems to monitor and restrict activity. I can log in through Firefox (or curl, for that matter) and not have my activity sent to the school.

Also, there is absolutely no legal way the school could force the monitoring of activity from an offsite computer (unless it were school-owned), even if it were technically possible. To secretly and silently install spyware on a parent's computer when the parent logs into the child's account would violate so many laws and constitutional protections I can't even list them.
