"If we don't raise our test scores, we lose money!"
"OK, let's ask easier questions - more people will pass - we'll keep our money!"
Of course, the excrement collides with the rotary air-mover when the kids reach the NAEP (or the real world), but the schools don't have a dog in that fight.
Just a theory.
Maybe Businesses can sue the schools for turning out poor quality employees. A Sector could agree to a set of standards all employees must meet for their given discipline. Instead of firing employees for poor performance, maybe they could sue the colleges and universities for a loss of productivity etc. Then fire the poor performing employee, and that ex-employee in turn sues the same school for creating the problem.
