Rater agreements in assigning stanford-binet items to Guilford's structure of intellect operations categories

Nineteen school psychologists assigned the 142 items in the Form L-M of the Stanford-Binet Intelligence Scale to the five Operations categories of Guilford's Structure of Intellect model, following flow charts prepared for this purpose by Meeker (1965). On the average, one rater agreed with another on about half the items, and their modal assignments agreed with Meeker's (1969) assignments on only 81 (57%) of the items. These levels of agreement are judged not to be high enough to justify classifying Stanford-Binet items in accordance with the Structure of Intellect Operations categories.
