Two alternative procedures of measuring group achievement under limited testing time are defined and empirically compared with respect to their efficiency in estimating a group mean and ranking a number of groups. The procedures are (A) administering the same set of items to each student in a group, and (B) administering a different set of items to each student in the group. Item scores on a college mathematics examination are employed in the comparisons.
