The Strong Interest Inventory (SII) is the most widely used instrument of its type in existence. The inventory is individually administered and can be used with high school students, college students, and adults. It is typically used in vocational counseling. The new 1994 version resembles the original published in 1927 both in the construction of the instrument and in the thorough empirical procedures traditionally employed in its development. Some changes have been made to maintain the contemporary focus and to make the presentation of the information more accessible. From a practical point of view, the test booklet and answer sheet are well-organized and attractive, with clear and concise directions. About 40,000 occupational group members met the selection criteria for the 1994 version. The male reference sample numbered 9,484 individuals, while the females numbered 9,467. Validity and reliability are supported through these samples. The new version appears to represent contemporary issues in vocational counseling, and seems to add an emphasis on the usefulness of the SII for exploratory purposes. (Contains 4 references.) (SLD)
