The differences in abilities are measured by the speed in which the child completes the task. Children earn from 0 to 6 points per page depending on the speed of correct responses. Specificity is ample for all age groups. The Speed of Information Processing subtest is described on pages 255 to 260 in the DAS Administration and Scoring Manual and discussed on pages 70 to 73 in the DAS Introductory and Technical Handbook. This is the only DAS subtest that does not utilize a decision point.
All children take all items in a specific booklet unless they reach an alternative stopping point.
Children using Booklets B or C who make two or more uncorrected errors per page on two of the first four scored items, are discontinued on that booklet. Examiners should then drop back to an easier booklet. It is important for both administration and timing that the examiner, and not the child, turns the pages of the booklet. Timing begins when the child had made a mark in the first row of items and stops when the child makes a mark in the last row. Examiners should encourage the child to respond quickly throughout the subtest.
