It is only natural for parents to wonder occasionally if the development of their preschool child is going well. Noting that psychologists have developed many normative scales to indicate how an individual child compares with others of the same age in similar populations, this parent brochure provides guidance for evaluating a child's behavior and achievements and for assessing what aspects of the child's development need special encouragement, support, or intervention. Topics covered in the brochure are: what categories of behavior to assess--including eating, sleeping, and playing--and when to intervene. Sources for additional information are included. (HTH)
