A measure of student patterns of item response is usually interpreted as a measure of carelessness or guessing. However, when aggregated to the class level, it was shown that the index identifies classes that have a poor match between test content and instructional coverage. In particular, Sato's (1980) caution index identified classes whose pattern of time allocation across content areas was atypical. In addition, it was found that the mean caution index for a class can best be interpreted knowing the within‐class standard deviation of the index.
