The Black-White Test Score Gap in Young Children:Contributions of Test and Family Characteristics

Abstract

This study examined Black-White test score gaps in young children. Scores from a receptive verbal test (Peabody Picture Vocabulary Test-Revised [PPVT-R]) and 2 full-scale intelligence tests (Stanford-Binet Intelligence Scale and Wechsler Preschool and Primary Scale of Intelligence [WPPSI]) were examined in 2 samples: (a) the Infant Health and Development Program: 315 premature, low birth weight 3- and 5-year olds; and (b) the National Longitudinal Study of Youth-Child Supplement: 2,220 3- to 4-year-olds and 1,354 5- to 6-year-olds. Questions addressed by the study included the following: Would similar test score gaps be seen on both tests and at both ages? Would gaps be reduced by controlling for family conditions and home environment? Would similar gaps be seen for the different tests? Fifteen- to 25-point differences in Black-White test scores were seen at both ages. The addition of demographic conditions reduced the disparities to 9 to 17 points. Including home environment measures further reduced the disparities to 4 to 13 points. Test score gaps were 11/2 to 3 times larger for the PPVT-R than for the Stanford-Binet Intelligence Scale and the WPPSI.
