If there is a possibly you'd medicate him, or you are thinking of potential therapies or accommodations for ADHD, then I would go ahead and get an eval right now...just disregard the teacher's assessment if you don't think it's valid. When DS had his eval the psych sent me 2 different teacher forms. Is there another teacher who could evaluate him? You probably don't need it though. There are lots of kids who are homeschooled or don't have teachers who know them well enough to fill out an inventory, but still get ADHD diagnoses.
