The purpose of this research was to establish the concurrent and predictive validity of the Phelps Kindergarten Readiness Scale, Second Edition (PKRS‐II; L. Phelps, 2003). Seventy‐four kindergarten students of diverse ethnic backgrounds enrolled in a northeastern suburban school participated in the study. The concurrent administration of the PKRS‐II and the Woodcock‐Johnson III Brief Intellectual Ability Scale (R.W. Woodcock, K.S. McGrew, & N. Mather, 2001a) occurred in the fall of the kindergarten year. To assess predictive validity, the Woodcock Johnson III Tests of Achievement (R.W. Woodcock, K.S. McGrew, & N. Mather, 2001b) was administered in the spring of that year. All concurrent and predictive correlations were significant. Based on the results of this study, the PKRS‐II may be used with confidence to screen for children who may be at risk for academic difficulties. © 2005 Wiley Periodicals, Inc.
