American public education has been a joke since integration... Sorry, its not PC but its true.
Black students came to integrated schools so far behind that rather than fail them they dumbed down everyone to move them along.
NO, it wasn’t he black children’s fault, they were given a lousy education up to that point... they had no chance to be on par with their peers when they integrated, but rather than working to lift those students up, they lowered expectations and have been doing so every since.
When Bill Clinton was governor of Arkansas he wanted to get a reputation for improving education in the state, so they had the idea of making all the public school teachers pass a competency test. I think it was basically something an intelligent fifth or sixth grader could pass. He got a lot of push back because so many minority teachers couldn’t pass the test.
