AN EVALUATION OF DIFFERENTIAL PREDICTION OF WIAT ACHIEVEMENT SCORES FROM WISC-III FSIQ ACROSS ETHNIC AND GENDER GROUPS

This study examines differential prediction of WIAT achievement scores based on WISC-III FSIQ in white as compared with African American and Hispanic children, and in females as compared with males. A procedure which allows simultaneous comparisons of slopes and intercepts across groups is employed. The results are consistent with previous research findings in supporting the general absence of bias in predicting achievement from IQ.
