| Abstract: | This study examined the stability of the Kaufman Assessment Battery for Children (K-ABC) for a sample of at-risk preschool children. Over a 9-month time interval, the stability coefficients (corrected for restriction in range) for the global scales of the K-ABC ranged from .78 to .88. The stability coefficients (corrected for restriction in range) for the K-ABC subtests ranged from .65 to .79. It was concluded that scores on the K-ABC for at-risk preschool children display adequate stability, but that the Simultaneous scale appears to be more amenable to change than either the Sequential or Achievement scales. |
