When I taught, up to 2 years ago, I taught the most severely mentally and physically disabled children. They had IQ’ s ranging from a couple of months up to 1 year old, and these high school students. Up until s few years ago, these kids were exempt from taking the test, however, now, they are required to take aofified version of the test, and most fail, obviously. Then you have the infux of non-english speaking students. They have to take the test in English. Obviously, if these can’t speak, read or write English, they are going to fail the test. If you want a true representation of how kids are doing, don’t have kids with cognitive disabilities and kids who don’t have English skills take the test. This all started under Bush2 and made worse by Obama.
