Convergent and discriminant validity evidence was examined for scores on the Spanish Record Form of the Bracken School Readiness Assessment, Third Edition (BSRA-3). Participants included a sample of 68 Hispanic, Spanish-speaking children ages 4 to 5 years enrolled in preschool programs in Puerto Rico. Scores obtained from the BSRA-3 Spanish Record Form were compared with scores from the Nonverbal Index of the Kaufman Assessment Battery for Children, Second Edition, and the Preschool and Kindergarten Behavior Scales, Second Edition. As expected, the correlation between school readiness scores and nonverbal intelligence was significant and moderate in the positive direction and the correlations between school readiness scores and behaviors were low. Discriminant validity evidence for BSRA-3 scores was demonstrated using Steiger's Z test to compare correlations of similar and dissimilar constructs. As hypothesized, significant results emerged.
