Identifying Academically Gifted English-Language Learners Using Nonverbal Tests: A Comparison of the Raven, NNAT, and CogAT
Lohman, David F.; Korb, Katrina A.; Lakin, Joni M.
Gifted Child Quarterly, v52 n4 p275-296 Fall 2008
In this study, the authors compare the validity of three nonverbal tests for the purpose of identifying academically gifted English-language learners (ELLs). Participants were 1,198 elementary children (approximately 40% ELLs). All were administered the Raven Standard Progressive Matrices (Raven), the Naglieri Nonverbal Ability Test (NNAT), and Form 6 of the Cognitive Abilities Test (CogAT). Results show that the U.S. national norms for the Raven substantially overestimate the number of high-scoring children; that because of errors in norming, the NNAT overestimates the number of both high-scoring and low-scoring children; that primary-level ELL children score especially poorly on the NNAT; that the standard error of measurement was twice as large for the NNAT as for the Raven or the CogAT; that ELL children scored 0.5 to 0.67 standard deviations lower than non-ELL children on the three nonverbal tests; and that none of the nonverbal tests predict achievement for ELL students very well. (Contains 8 tables, 5 figures and 5 notes.)
