It's sickening that schools sign agreements that basically let third parties collect data on students... I'm guessing there's a loophole somewhere where that date can be used after they turn 18...

When I went back to school for my Master's degree, I had the highest confidentially settings I could set. If I wanted to ask questions on a homework or project, the school required I gave my name, email, and course information, along with the content of my post to Piazza.

The argument and agreement was that they can't use my information unless I also am a member on their website outside the context of Piazza... Funny enough, I used LinkedIn... So since I want to use LinkedIn, my school information privacy is violated.

I imagine there's a similar goal with high school students. As soon as they turn 18 and claim that on LinkedIn, they can go back and mine their high school and middle school data.
