@Mona: We're about the same age. "Special Ed" in Michigan during the 1960s was for kids whose mental faculties were obviously diminished. Those kids were shunned by the rest of the students. Parents would threaten their kids with putting them in Special Ed classes if their grades didn't improve, or they would humiliate their kids by implying they belonged there.
"Autism" was one of those words that was whispered between adults when describing someone else's child -- one that likely had been "sent away" by his or her family, or that was "kept inside" and away from the other kids. There was a lot of social stigma involved in even admitting that something could be not-quite-right with one's own children.
Maybe I was better off for not being assessed.
