The Differential Ability Scales™ (2nd ed., DAS™–II) is unique in that it goes beyond cognitive ability testing to give insight into how a child processes information. Developed for psychologists, this child-friendly test provides information that enables you to predict their likeliness to succeed in education and to craft appropriate interventions and/or recommendations for the classroom and home. With out-of-level testing and child-appropriate start points, this time-tested assessment gives you the speed and flexibility you need for children who may struggle with longer tests.
