It wouldn't be making a spectacle of him, because the testing would be private. However, unless your pediatrician has some reason to suspect disabilities, I think the suggestion that your son be tested at such a young age is very strange. Is there some reason to test him now? I only ask because absent the specter of LDs, it seems like a big waste of money and time; you can't use the scores for access to services, and they won't really be useful in raising him either. Everything I read also says that the younger you test a small child, the less accurate the results may be long-term.
ETA: I agree with ColinsMum; if you're not worried at all about autism, I'd consider turning down testing at this stage.
