Intergenerational Predictors of the Black-White Achievement Gap in Adolescence Jelani Mandara Northwestern University
Background 1. Several family based factors likely account for some of the Black-White achievement gap. 2. Previous studies have been limited due to: a. Only examining a few family factors at a time. b. Not examining the effects of intergenerational (i.e., grandparents) factors. c. Using poorly measured variables.
The Current Study Purpose: 1.To determine if home-based factors can explain racial differences in achievement test scores. 2.To determine the unique effects of three generations of home-based variables. 3.To determine which factors account for most of the variance in the racial differences.
Methods Participants 1. The National Longitudinal Survey of Youth ( ) 2. Mothers (N = 1367) a.Ages 14 to 21 in 1979 b.Diverse SES backgrounds c.533 African American, 834 European American 3. Adolescents (N = 2108) a.At least age 10 by the the year 2000 b.50% male/female c.823 African American, 1285 European American

Summary 1. The test score gap dramatically decreased in one generation. 2. The gap was almost completely accounted for by home-based factors. 3. Grandparents’ factors assessed up to 20 years earlier accounted for 20% of the gap. 4. Adolescent health, test taking motivation, and parental demandingness were particularly important. 5. Grandparent and SES factors may be mediated by parenting and adolescent factors.
