Abstract
Summary. Studies of the predictive validity of psychological tests are relatively rare in comparison with studies of other types of test validity. This is not surprising as studies of most types of test validity (e.g., concurrent, construct) require the collection of data at only one point in time while studies of predictive validity can only be done within the context of longitudinal research. There have, however, been relatively few such studies and only a few of these have studied the predictive validity of tests. The paucity of longitudinal studies is, no doubt, a result of the many problems involved in the establishment and maintenance of such long term research (Mednick, 1981). This paper reports data on the predictive validity of three tests, the Reynell Developmental Language Scales, the Peabody Picture Vocabulary Test, and the Stanford‐Binet Intelligence Scale.
