Hi BonnieNova! Keep the dialogue going with the preschool as much as possible. Any accommodations that your DS was not yet approved for may become more obviously necessary in a group, school setting as well as more obvious with age.I know that my son is by far not the only child I've met where because of higher IQ and high verbal ability, autism spectrum disorders were not even considered. However, the more frequent and intense the social interactions, and the older the child and the higher the expectations, the more obvious special needs become. The input of the preschool teachers, and later the classroom teachers, could be what helps to show that your son does require some special services. Get as informed as you can as to your child's educational rights, and then keep at it no matter the outcome. (By the way, DS does have the formal diagnoses now, of ASD, although we were told by the old diagnostic system it would have specified Aspergers, now they are just saying ASD and naming strengths and weaknesses. Like your DS, he was ahead by a couple of years in verbals, in the 5th percentile in fine motor, but also a slow processing speed, gifted patterning, logic and math. Bright kids are hard to diagnose, but not impossible, so keep involved if you know something is up!)
