The Self-Directed Search for Educational and Vocational Planning (SDS) is a self-scoring, self-administering instrument designed by John L. Holland, author of the Vocational Reference Inventory. Preliminary use of the SDS led to the speculation that some people were very dissatisfied with their results and others were quite pleased. Of the 4,631 incoming freshmen at the University of Maryland who completed the SDS 485 were extremely satisfied and 343 were extremely dissatisfied with their results. The codes for these groups were compared using chi-square and t. Results indicated that a greater percent of those dissatisfied did not obtain codes with a corresponding occupation listed in the SDS booklet. Also the satisfied group received more Artistic and Investigative codes while the dissatisfied group received more Conventional codes. The possibility that the SDS favors people from upper socioeconomic levels and implications of the results were discussed. (Author)
