Technique for weighting of choices and items on I.B.M. scoring machines

A technique has been developed which permits the weighting of responses of test items on the I. B. M. scoring machine on the initial scoring, heretofore impossible. This is done by making the length of the response lines on the answer sheet longer or shorter as weights are needed. It is anticipated that this method will prove useful wherever differential weighting serves to increase the validity of tests.
