My son who is in 8th grade and who has ADHD is going to be tested to see if he qualifies for Other Health Impaired Services. He had an IQ test in 3rd grade and he did quite well.( 121 overall and performance 127 and verbal of 112). This was before we knew he had ADHD. The pychologist at the school said that they will retest his IQ but she expects that there will be a drop in it. Is this to be expected with ADHD? SHould I have him tested at the school or privately? My concern is that the school starts very early and he is always suffering from lack of sleep (since he is a night person).I can’t imagine that he would do well there. She said that the test would not matter for OHI but they need to do it. Am I being silly? Any thoughts? He currently has a 504 plan.
