Compared with private-school teachers, anyway. Obviously no jawdropping surprises here, but still, these graphs are pretty stark:

Public v. Private - serious problems, elementary (color)

Public v. Private - serious problems, secondary (color)

Not sure which bar is the saddest here. Maybe all of them.

Disclaimers: The survey data comes from ’07-’08, ’03-’04, and ’99-’00. The survey questions seem to have shifted from year to year. I took the most recent data for each question, and always drew public and private data from the same year for a given item.
