The predictive validity of the Kaufman Assessment Battery for Children (K-ABC) was investigated for 29 elementary school children (14 females and 15 males) over an eleven-month period. The K-ABC evidenced nearly identical global scale standard scores as the Peabody Individual Achievement Test; correlation coefficients in a moderate (.40-.83) range were noted between the two tests. The K-ABC appears to have acceptable predictive validity for normal elementary-aged children.
