We first tested at age 4 and learned very much about our child. It helped us consider what type of learning environment he needed and decide if it was worth the tuition to send him to a Gifted Private School. If testing could change some of your decisions or if you have concerns, then you would probably find it helpful. Many districts are not likely to provide IQ testing without compelling reasons to do so. If there is something you hope to gain or a question you need an answer to now, I would seek private testing.
