Strong Interest Inventory® (STRONG)

Work | Educational | Career Assessments | Academic Functioning | Organisational Development

The Strong Interest Inventory assessment is based on John Holland’s RIASEC model theory, andone of the world’s most widely respected and frequently used career planning tools. It helps individuals in both academic and business environments to develop their talents 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. The assessment is based off the premise that there are six main types of working environments and that individuals prefer working in one of these environments that allow them to exercise their skills and abilities, express their attitudes and values, take on problems and roles they find stimulating and satisfying, and avoid chores or responsibilities they find unpleasant or daunting.


The Strong measures interests in four main categories of scales:

  • General Occupational Themes (GOTS): Measure basic categories of occupational interests - Realistic, Investigative, Artistic, Social, Enterprising, and Conventional (RIASEC).
  • Basic InterestScales (BISS): Measure clusters of interest related to the GOTS in areas such as Athletics, Science, Performing Arts, and Sales.
  • Personal Style Scales (PSSS): Measure preferences for and comfort levels with Styles of Living, Work Style,Learning Environment, Leadership Style, Risk Taking, and Team Orientation.
  • Occupational Sales (OSS): Measure the extent to which a person’s interests are similar to the interests of people of the same gender working in 130 diverse occupations, such as Accountant, Bartender, and Computer Programmer.


The Strong can be used for the following purposes:

  • Informing academic, vocational and career decisions
  • Stimulating discussions between student, parent and teacher
  • Stimulating mid-career evaluation
  • Helping to understand job satisfaction or dissatisfaction


The following software reports are available:

  • The Strong Profile Report: This is a highly personalised report that paints a clear picture of how the client's specific interests and preferences link to various jobs, work settings,and career fields.
  • The Strong Profile, College Edition: This report helps students explore the path that is right for them by identifying specific college courses, jobs or internships, and extra curricular activities that will allow them to express their unique interests and personal style.
  • The Strong Profile, High School Edition: This report helps high school students to explore various fields of study;discover satisfying work-study, volunteer, or summer job opportunities; and examine a wide range of work environments.
  • The Strong Interpretive Report: This report builds on the Strong Profile by applying key learning to create a richly textured road map for exploring and pursuing a rewarding life of work and leisure.
  • The Strong Interest Inventory® and Skills Confidence Inventory: This report is linked to the six General Occupational Themes, and graphically illustrates how clients’ interests compare to their level of confidence in performing certain activities.
  • The Strong Interest Inventory and MBTI® Career Report: This report integrates clients’ General Occupational Themes, Basic Interest Scales, Occupational Scales, and Personal Style Scales from the Strong with their MBTI® results to offer career direction and identify relevant occupations, with emphasis on those suggested by both instruments.
