Assessment subtests are like special tasks or exercises that help experts understand different things a child can do. They look at specific skills such as talking, remembering, paying attention, solving problems, or using their hands. These tasks help experts learn what a child is good at and where they may need extra help. Experts can figure out the best ways to support a child’s unique abilities by doing many different tasks. Assessment subtests are important because they give a complete picture of what a child can do and help grown-ups make the right choices to help them succeed.
