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, T N. Mather, 2001 a) 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, T N. Mather, 2001 b) 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. (c) 2005 Wiley Periodicals, Inc.

Mather，2001 a）同时管理发生在幼儿园的秋天。为了评估预测效度，当年春天进行了《伍德考克约翰逊三世成就测验》（R.W. Woodcock，K.S. McGrew，T N. Mather，2001 b）。所有并发和预测相关性均显着。根据这项研究的结果，可以有把握地使用PKRS-II筛查可能面临学业困难风险的儿童。 （c）2005年Wiley Periodicals，Inc.
