School grades are official documents, and anyone can request grades from the archives. Journalists often like to see the school grades of newly elected government officials.
This source is the Swedish National Archive but this also applies to non-historical grades.

Right, ok, but you can only request final grades. So you can only do this once on 15-year-olds, after they've finished primary school. And the next time you can do this on a person, they're gonna be 18 and have graduated high school.
I thought the primary school final grades were protected until you're an adult, but apparently not.
