Abstract: The purpose of this study was to provide a guidance to senior middle school students who plan to choose college speciality and to undergraduate students who are going to choose the second speciality. With the Self-Directed Search, this study sampled 1227 college students in 8 universities in Wuhan, China. The results showed that SDS has necessary reliability and validity. By interviewing the students or their instructors, the speciality three-letter codes which were built up to replace the raw scores with the standard scores are of good validity and can provide suitable description of speciality. The results also showed that the consistency of the Speciality Finder and the Holland Occupations Finder are limited. The Holland Occupation Finder might be revised so that it can be applied to domestic conditions.

Key words: SDS, college speciality, three-letter codes, occupation
