The SII contains 317 items that determine your level of interest in occupational institutions, professional activities, hobbies, leisure activities and diverse types of people. It comes with a detailed printout of results.

One way of exploring majors and careers is by looking at occupations according to occupational interest. John Holland conducted research that divided jobs and job seekers into six broad categories: Realistic, Investigative, Artistic, Social, Enterprising and Conventional. Your Holland Code is a generalization, not an exact fit. However, it might help you discover where you can find occupational satisfaction.
