Determined whether the new scoring system on the revised Self-Directed Search (SDS; J. L. Holland, 1977) is an improvement over the original edition. It was hypothesized that the revised scoring system would lead to fewer errors than the previous one, since the new system appears to be more direct and to involve fewer transformations of subscale scores by the user. Results of a z test using incoming college freshmen data show that the error rate in the summary code for the revised edition of the SDS was significantly lower than the error rate for the original SDS, but no differences were found between the 2 forms with respect to high-point-code error rates.
