So, a particular school system decided to add SSN to the student profile? Or Canvas requires it?
It's not required. I don't know precisely what her district is doing or why - I don't work there But she unprompted brought up that a lot of the minors' PII was in there including SSNs.
I'm guessing that Canvas just sort of lets you put in whatever data you want, and someone evidently decided that putting the student's SSNs in there made sense...
