Speaking as a teacher, the idea behind NCLB was not bad. What was bad was how they set the requirements. I wonder if the general public realizes that a significant portion of special ed kids are 4 grades or more below grade level. There are many that are barely above a vegetative state. Then there are schools where there are over 30 languages that are the students 1st language, many of which do not speak English at all? NCLB requires all these students to complete and submit standardized tests. Oh, accomodations can be made, which may work for a child with mild cerebral palsy, dyslexia, other psychoneuro problems, but not for those that are unable to hold a pencil, respond to oral prompts, etc.
Which neighborhoods are likely to have more of the above problems? Which schools?
Then there are 'high quality schools', with perhaps a .05 poverty rate. Of those small number, they are measured separately, thus if the 1 or 2 kids don't perform at a passing level, the school can end up on a 'warning list.'
It's not the tests, it's not the kids, it's not the teachers, it's the law that is problematic.
