An I.Q. test is a measure that assesses a child´s aptitude or ability in different domains, whether verbal, whether expressing him or herself verbally or understanding language, visually spatially. So looking at puzzles, mazes, sort of understanding the relationships between objects in the environment, memory, rate of taking in new information, and the ability to kind of problem solve mentally. So those are some of the main domains we look at although there are more areas of fluid reasoning, long term memory for crystalized information. I.Q. testing is important in generating or developing sort of an idea of where a child is with regard to aptitude at a given stage. The difference between I.Q. testing for younger and older children is not that different. It is just different test and they have sort of developmentally lower or higher expectations in the different areas of attention, concentration, memory, verbal expression and so forth. For very young children, we look more in the domains of motor skills, creative play, eye contact and those are areas that we kind of look at to see if there is an area of delay. More commonly we look at that. But also, I think one of the things that parents may find for their children is in the area of giftedness that we see that they meet development milestones at a much earlier age whether in talking or in coordination, walking and so forth. So those would be two areas that we would see or want to approach differently for a child of say three than a child of nine or 10.
