Wow. A lot of K-12 students probably don't even know their own SSN off the top of their head, much less understand the impact of having it stored in this way. I can't fathom why it would be necessary for the SSN to be tracked by the school. At most, the school district as a whole might want a record so they could make sure kids are getting schooled but putting that into Canvas doesn't make any sense to me.

Agreed, seems wild to me that anyone in 2026 is using SSN as an identifier in a system that's not doing some kind of tax reporting. It's kryptonite for any other purpose.

Oh, it's insane and I recoiled when she mentioned that.

But it is 100% happening.

People do amazingly stupid things with systems, especially when they don't have enough people with the expertise to set them up properly, so they just throw things in there without stopping to think about whether or not it's a good idea.

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.

It would be nice if system owners stopped thinking "we'll just ask for all the info in case we need it" and instead "we might get sued (or ransomed, or both) because we are collecting this."

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...

They already have your SSN, as does anyone else who wants it.

True. It's more yikes about what this says about the technical knowledge in that school.

That is a big yikes, but definitely not the norm. Most school districts switched from using SSN as their SIS identifier decades ago.
