I should always start my class in a routine way so the student with autism knows what to expect and will not feel overwhelmed or uncomfortable. 

That there are programs for autistic high schoolers to see what college is like and can attend for a few days to get a better grasp of what they can expect if they choose to attend college. 

That there is no cure and that the term aspergers is not really a diagnosis. And that diagnosing autism is muli-faceted. 

I have learned that autistic students may not be able to understand sarcasm or read people's behavior cues as well as students without autism. That some are highly intelligent but like to be on their own. I also did not know that they had seizures and GI problems.
