Described are the effects of four sets of instructions on the observed item inter‐ correlations of current events and subtraction items. The four conditions were: (a) general objective, (b) behavioral objective, (c) behavioral objective plus test item, and (d) behavioral objective plus item‐form. Two tests, one in each subject matter, constructed by selecting four items generated from each of the experimental conditions, were administered to 51 seventh grade children. Not found were the expected tendencies toward greater homogeneity among items produced under the three conditions employing behavioral objectives.
