ASQ:SE-2 relies on parents to observe their child and to complete the simple questionnaires about their child’s abilities. Having parents complete the social-emotional questionnaires is not only cost-effective, but also enhances the accuracy of screening by tapping into parents’ in-depth knowledge about their children. Using parent-completed tools also fulfills the spirit of Individuals with Disabilities Education Act (IDEA) amendments, which call for parents to be partners in their child’s assessment and intervention activities.
