The purpose of this study was to provide test-retest reliability data for Holland's Self Directed Search for Educational and Vocational Planning (SDS). Sixty-five subjects were administered the SDS 7-10 months after they completed it during freshman orientation. Results indicated little change in summary codes obtained by subjects. Median reliability coefficients were .75 (Pearson Product Moment), 87 (Average Common Elements), and .92 (Spearman Rho). These coefficients are generally higher than the homogeneity of content coefficients (KR20) for subscales reported by Holland (1971) and the test retest coefficients reported by Baldwin (1971). Results were discussed and it was concluded that the SDS shows an acceptable amount of reliability, although subjects incorrectly scoring their own booklets is a source of unreliability. (Author)
