This study demonstrated that the design of cur rent intelligence test short forms could be improved by employing a more effective method of item selec tion based on psychometric theory. Two short forms of the recently published WISC-R were developed, one employing a design determined by empirical item analysis results of the standard test battery and the other employing the well-known Yudin scheme determined by systematic random selection of test items. In all analyses the item analysis method of item selection was shown to yield more accurate results than the Yudin procedure. Practi cal usefulness as well as limitations of the present WISC-R Short form are discussed.
