Strong-Campbell Interest Inventory

Strong-Campbell Interest Inventory

The Strong Interest Inventory (SII) is an interest inventory used in career assessment. The goal of this assessment is to give insight into a person's interests, so that they may have less difficulty in deciding on an appropriate career choice for themselves. It is also frequently used for educational guidance as one of the most popular career assessment tools. The test was developed in 1927 by psychologist E.K. Strong, Jr. to help people exiting the military find suitable jobs. It was revised later by Jo-Ida Hansen, and David Campbell. The modern version (2004) is based on the typology (Holland Codes) of psychologist John L. Holland. The Strong is designed for high school students, college students, and adults, and was found to be at about the ninth-grade reading level (Blackwell and Case, 2008, p. 122). Unfortunately the newly revised Strong is available only in English, unlike the previous version.
