And Squnney I am not unsympathetic to your position either. There is something fundamentally wrong with thinking a 53% success rate, based on reasonable criteria, merits even keeping a school's door open much less thinking it acceptable. 81% is not acceptable either. New Mexico schools have typically done even worse. I think the problems run very deep and there is no way they can all be hung on testing. Private schools are showing nearly 100% graduation rates and producing high SAT's etc to boot.
I'm still saying lets try the voucher program. If enough parents opt for private schools, the public schools will have to do things differently to compete. If that means reforming the system to get rid of the kids who will not learn and who prevent others from learning, so be it. It wouldn't be hard to put together trade schools to teach the non-learners a marketable skill or two so they can support themselves. Get the losers out of the classroom and skilled teachers, abetted by parents, will inspire their students to want to learn.
I have even toyed with the idea of refusing driver's licenses to any kid who a) did not have a highschool diploma or b) had not successfully completed a vocational trade school or c) had not reached age 21. That alone should provide enough incentive to keep some of them focused on getting an education.
