This is a clinical instrument for the evaluation of preschool and elementary school
            children (2 1/2 through 12 1/2 years of age). Developed from recent research and theory
            in neuropsychology and cognitive psychology, it assesses problem-solving ability using
            both simultaneous and sequential mental processes.
         
         It also includes an achievement scale which assesses acquired knowledge in reading
            and arithmetic. It is an improved technique because it generates data that coincides
            with recent research relating particular functions to parts of the brain.
