My 7 year old son was recently tested through school due to some behavior issues both the teacher and I noticed (reversing letters, organizationally challanged, talking back, difficulty staying on task, inability to deal with changes in plans, excessive talking, repeating himself, etc).
How much of a problem is the inability to deal with changes in plans? Is he just reluctant, or does he have meltdowns?
Were I in your shoes I would seek a private evaluation for Asperger's/ autism spectrum disorders. Sometimes it doesn't get caught in bright kids because they're so bright. This batch of issues has enough Asperger's flags in it that you don't want to rely on just the school's opinion-- get a neuropsych or a developmental pediatrician who really knows autism and giftedness to evaluate.
