Predictive validity of a short-form WPPSI with prekindergarten children: A 3-year follow-up study

A short-form WPPSI was administered to 58 prekindergarten boys, who were tested subsequently as to school progress at the end of the kindergarten, first-, and second-grade years. IQs were not correlated significantly with kindergarten test scores, but significant correlations were obtained with Listening and Mathematics in grade one and with Listening and Writing Skills in grade two. A restricted range of IQs apparently led to the relatively low rs obtained in this study. Until more impressive predictive validity data are obtained, caution is advised with regard to the use of the short-form WPPSI for school admission purposes.
