The Strong Interest Inventory® assessment is one of the world’s most widely respected and frequently used career planning tools. It has helped both academic and business organizations develop the brightest talent and has guided thousands of individuals—from high school and college students to mid-career workers seeking a change—in their search for a rich and fulfilling career.

Developed by psychologist E.K. Strong and continually refined and researched, the Strong Interest Inventory® is an indispensable tool for the modern workplace. It benefits from a variety of lenses through which career interests and preferences can be assessed: starting with a broad view of general fields of interest, the inventory goes on to suggest specific career options for the individual, and gives them an insight into their likely professional style once in a job.
