Examines the incremental validity of Differential Ability Scales (DAS) factor scores in predicting standardized achievement scores in Word Reading, Basic Number Skills, and Spelling by using a nationally representative sample stratified on gender, ethnicity, geographic region, parental education, and educational classification. Results show that improvement was consistently too small in size to be of clinical significance. (Author/JDM)
