Current research on the use of revisions of intelligence measures with ethnically diverse populations and younger children is limited. The present study investigated the utility of the Stanford-Binet Intelligence Scales, Fifth Edition (SB5), with an ethnically diverse preschool sample. African American and Caucasian preschoolers, matched on age, gender, and parental education, were found to have similar patterns of high and low scores on both the composites and all subtests of the SB5. The present study also found that African American and Caucasian preschool children did not differ on overall cognitive ability as measured by the SB5 Full Scale IQ. Implications and suggestions for further research are discussed.
