Abstract	Two types of answer-copying statistics for detecting copiers in small-scale examinations are proposed. One statistic identifies the "copier-source" pair, and the other in addition suggests who is copier and who is source. Both types of statistics can be used when the examination has alternate test forms. A simulation study shows that the statistics do not depend on the total-test score. Another simulation study compares the statistics with two known statistics, and shows that they have substantial power. The new statistics are applied to data from a small-scale examination (N = 230) with two alternate test forms. Auxiliary information on the seat location of the examinees and the test scores of the examinees was used to determine whether or not examinees could be suspected. (Contains 2 figures and 5 tables.)
