Strong Interest Inventory

The Strong Interest Inventory (SII) is an interest inventory used in career assessment. As such, career assessments may be used in career counseling. 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 Edward Kellog 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 of 2004 is based on the Holland Codes typology 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.
