Design Fluency (NEPSY) This test assesses the child's ability to generate novel designs as quickly as possible on structured and unstructured arrays of dots. The child makes as many different designs as possible by connecting two or more dots.

Design Fluency (D-KEFS) This test measures ability to generate novel designs as quickly as possible, response inhibition, and cognitive fleibility. The test is composed of three conditions. In each, the child is presented rows of boxes each containing dots that the examinee must connect, with four lines only, to make
different designs. Conditions are 1. Draw as many designs as possible; 2. Connect only unfilled dots, leaving filled dots blank; and 3. Alternate connections between filled and unfilled dots.
