BLACK/WHITE IQ DIFFERENCES: DOES AGE MAKE THE DIFFERENCE?

Data are presented on racial differences from the norms of the Kaufman Assessment Battery for Children, the recent renorming of the Wechsler Adult Intelligence Scale-Revised, the Stanford-Binet IV, and Raven's Progressive Matrices. The premise of the present article is that, while the one standard deviation IQ difference between Black and White adults has remained constant, IQ differences between Black and White children are declining. These data are discussed in the context of previous studies on possible racial bias of IQ tests, as well as marked changes in educational and economic opportunities that have occurred in the United States in the decades since Jensen's (1969) article.
