My opinion--and it's only my opinion, completely unsupported by any evidence--is that the problem with graduation requirements is at the low end of the spectrum, not the high end. Kids who can't pass today's requirements aren't going to be able to pass tomorrow's. What does Oregon gain by this?
Those who graduate will definitely have a better education, and that's a good thing. But what about those at the bottom? I wonder what Oregon's real drop-out rate is, and how they're addressing that with these new requirements.
