Changes in the 1994 Strong Interest Inventory (SII; Harmon, Hansen, Borgen, & Hammer, 1994) are reviewed and evaluated according to a set of criteria originally proposed by John Holland (1975) and revised for this paper by the authors. Data from over 50,000 people in 50 occupational groups representing new and resampled occupations were involved in the 1994 revision. New General Reference Samples (GRS) containing over 18,000 people were used in scale construction. Every item and scale was reconsidered. Nearly every scale has been revised. A case study illustrating the use of the revision is presented. It also serves to introduce the 1994 score report profile.
