HIGH SCHOOL LEVEL LITERACY TESTS FOR TEACHERS ARE RACIST
All examinations discriminate among people. That's their purpose. The purpose of bar exams is to discriminate on knowledge and skills. Medical licensure examinations discriminate on knowledge and skills. And let's discuss commercial pilot's licenses.
When you look for something that tests discriminate on, you can find it. IQ, study habits, educational background, character traits, family background, race, age, height, etc. You can find whatever stats you look for, but all the tests are looking for is to see who can do the thing, and who can not do it. That is discrimination of the able from the unable. It's the individual that matters.
For Christ's sake, if you can't understand simple written English, how can you be paid teach it? You might almost imagine that teaching was just a government job.
