- The teacher (you) or other student is reading a book and mispronounces a word, skips a word, or doesn't pause long enough at a punctuation mark (or whatever the child is currently being instructed to do at school). This child will blurt out with authority, "You skipped a word..."
- Another child does something such as getting out of his seat, talking out, etc. This child is the self appointed 'rules police'. He will immediately call attention to the faux pas. (But he usually misses his own behavior lapses and will argue to the death about why he was not in the wrong - in his own mind he would never break a rule so he likely has some legitimate 'rationalization' to excuse such an unthinkable indiscretion).
- The assignment is to quickly sketch a picture of .... This is the child who continually erases his picture, asks for a new sheet of paper so he can start over, or takes 3X as long to finish because he has to insert every minutia of detail into his 'quick sketch'.
- Unfortunately this can also be the child who is so overwhelmed at a task, because in his mind making it perfectly requires herculean effort, that he will often quit before he even tries to begin.
As I typed that last example, I recognized a bit of myself in that one... does anyone else reading this have some of these traits of perfectionist? Of course we all share some traits with our kids on the spectrum. We and they are both cut from the same human cloth. The difference between neurotypicals and those with ASD is the degree to which these traits affect their lives. We can recognize the problems in ourselves, most of the time, and then we can exert self-control, employ self-talk, put the issue back into the proper perspective, and go forward to do what needs to be done. Individuals with ASD have a much more difficult time navigating this process.
How do we deal with this issue?
I have not conquered this at all but I will list some of the tools and resources I have employed or am planning on employing to help the children I see with the issue of perfectionism.
Social Thinking Curriculum: There are many pieces of this curriculum that are ideal in helping the child understand how constantly correcting others is perceived or received:
- Unexpected Behaviors: It is unexpected behavior to correct the teacher or parent over minor issues. It is also unexpected behavior to correct classmates; that is the teacher's job, not your job.
- Problem Scale: How big of a problem is it that the teacher skipped a word? If it is a #1 or #2 sized problem then you do not need to call attention to it, just ignore it because it does not really make any difference to the outcome. If the omission will result in a bigger problem (i.e. doing the wrong homework, etc.) then it is okay to point it out in the correct way.
- Thinking of Others: This is a perspective-taking task. How would you feel if someone pointed out every small mistake you made? Would it make you feel sad or angry or embarrassed? Then it probably does the same thing to others. It also interrupts the lesson or distracts others.
- Social Behavior Map: Construct this map to show the sequence of consequences and the negative outcome of constantly correcting versus the more positive outcome of overlooking minor mistakes.
Beautiful OOPS! is a book about turning mistakes into positives. A small tear, a drop of paint, a crumple all become an interesting part of the creation.
The Girl Who Never Made Mistakes: Beatrice never makes mistakes...never ever... until one day when she makes a very public mistake and learns that mistakes are okay.
Amelia Bedelia Books: Amelia constantly makesmistakes but in the end everyone laughs and still loves her!
A Bad Case of Tattle Tongue: Picture book about tattling and the negative aspects associated with this behavior. Again, picture books serve as excellent pre-packaged social stories. A social story typically only describes the desired outcomes. Whereas a picture book usually adds a moral or lesson learned.

This is a great tool to help learn to gauge size of emotional responses. It works along with the problem scale. Rate size of problem then rate size of reaction or emotion. Try to teach children that making a small mistake is a #1 or less size problem and we need to learn to overlook those things.
