Interest inventories are psychometric tools that help individuals discover their interests, preferences, and occupational strengths and challenges. These inventories use varying items in the form of multiple-choice questions to quantify a person’s likes, dislikes, ideals, and motivations. Interest Inventory assessment tests can be of great value when making decisions regarding career or educational pursuits, as they provide insight into the type of occupational tasks and work environment you prefer, college and high school academics and curriculum, as well as hobbies and general activities individuals may find fulfilling.

There are several popular interest inventories that are commonly used in university career centers, private career counseling practices, and through online administrators, each with its unique focus and approach. Online administrators generally provide the entire process from start to finish 100% online. When using an online administrator, assessments are completed on a desktop, laptop, or tablet, and your results are sent to you in PDF form to your email on file. Additionally, a complimentary consultation to review your results to understand your reports should always be offered as most interest inventories, such as the popular Strong Interest Inventory® and Myers-Briggs Type Indicator®, are Level-B Psychological Restricted Assessments, and the interpretation of your results is of the most importance.

Here are some of the most effective and popular interest inventories:

The Strong Interest Inventory (SII): The SII is one of the most recognized and verified interest inventory assessments available to the general public. It is used by psychologists, career counselors, and online certified administrators and is the go-to assessment for university and college career centers. It was first created in 1927 and has been revised for accuracy many times. Developed by E.K. Strong, Jr., and later modified by Jo-Ida C. Hansen and David P. Campbell, the SII compares the test taker’s interests with those of individuals in various occupations to suggest potential career matches.

The SII measures an individual’s occupational and personal interests in six categories: Realistic, Investigative, Artistic, Social, Enterprising, and Conventional.

Another popular interest inventory is the Campbell Interest and Skill Survey (CISS), a career tool that helps individuals match their interests and skills according to various occupational categories.

The CISS determines people’s interests and skills amongst seven occupational classifications, which are like but distinct from Holland’s RIASEC model, as can be found in The Strong Interest Inventory® line of assessments. The seven themes in the CISS are:

  • Influencing: Involves influencing, leading, and overseeing others.
  • Organizing: Involves organizing, arranging, and directing activities.
  • Helping: Involves working with people to provide encouragement, support, care, or assistance, as in counseling or a medical practice.
  • Analyzing: Involves researching, gathering, and evaluating information, such as in mathematics and science
  • Producing: Involves building, restoring, and repairing tangible products, crafts, etc.
  • Adventuring: Involves engaging in physically challenging activities or risk-taking tasks, such as in athletics, the military, and law enforcement.
  • Expressing: Involves creating or performing artistic, literary, or musical works.

The CISS is made up of 320 questions, with 200 focused on interests and 120 focused on skills. For each question, individuals express their interest level or skill, Strongly Dislike or Poor to Strongly Like or Excellent. The questionnaire generates scores for the seven occupational themes and 53 basic scales, providing specific information about the person’s interests and skills.
