The Evolution of the Black-White Test Score Gap in Grades K-3: The Fragility of Results NBER Working Paper No. 17960. National Bureau of Economic Research, March 2012. Also: http://www.nber.org/papers/w17960 Cohort(s): Children of the NLSY79 Publisher: National Bureau of Economic Research (NBER) Keyword(s): Early Childhood Longitudinal Study (ECLS-B, ECLS-K); Peabody Individual Achievement Test (PIAT- Reading); Peabody Picture Vocabulary Test (PPVT); Racial Differences; School Progress; Test Scores/Test theory/IRT Although both economists and psychometricians typically treat them as interval scales, test scores are reported using ordinal scales. Using the Early Child-hood Longitudinal Study and the Children of the National Longitudinal Survey of Youth, we examine how order-preserving scale transformations affect the evolution of the black-white reading test score gap from kindergarten entry through third grade. Plausible transformations reverse the growth of the gap in the CNLSY and greatly reduce it in the ECLS-K during the early school years. All growth from entry through first grade and a nontrivial proportion from first to third grade probably reflects scaling decisions. |
