I mean, not surprisingly, this is entirely geographic and system dependent. Do your high school teachers (or elementary) have to wear body cameras, practice administering narcan, and how to clear the chamber of a discovered gun, or do they get to 3D print parts for their classroom and go on field trips?
It's the outliers that are geographic and system dependent. Rank the schools and exclude outliers at both extremes. The remaining schools aren't filled with teachers acting like prison guards watching over illiterate students.
