About Strong and MBTI*

For more than 60 years, the Strong (SII) and MBTI psychometric assessments have helped millions of people world-wide gain a deeper understanding of themselves and their career interests. They have been continually researched and revised to reflect the latest changes in the workplace.


One of the most respected and widely used career development instruments in the world, the Strong helps you discover your true interests so you can better identify, understand, and often expand your career options. The 291-item inventory takes about 30-40 minutes to complete.

The Strong generates an in-depth assessment of your interests among a broad range of occupations, work and leisure activities, and educational subjects. It reveals interest patterns and presents results on a variety of complementary themes and scales:

  • General Occupational Themes map out broad interest patterns to describe personalities and preferred work environments. Your profile will include your unique theme code, corresponding with Holland's RIASEC theory.
  • Basic Interest Scales provide more specific information about your areas of interest, in accordance with your RIASEC theme set.
  • Occupational Scales relate your interest patterns to those of satisfied workers within the occupation.
  • Personal Style Scales describe your preferred style of working, learning, leading, risk-taking, and team participation.

As with the MBTI, please note that although the Strong is comprehensive and personalized, its purpose is not to give you an exact list of occupations that are guaranteed, perfect matches for you. That is not what career counseling and what these tools are intended to do. For example, even as specific as the Occupational Scales gets, its primary purpose is to show how your scores compared to score patterns of those within specific occupations. The assessment as a whole is meant to enhance self-understanding and help give direction to your own unique career exploration process.


The Myers-Briggs Type Indicator ® (MBTI®) instrument is a personality assessment questionnaire designed to make Jung's ideas about psychological type useful in everyday life. It identifies a person's four basic type preferences that combine into one of 16 different personality types. These results help you understand normal differences in the way people think, communicate, and interact-differences that can be the source of much misunderstanding.

The MBTI instrument has been used for more than 50 years to establish greater understanding between individuals. It has been taken by millions of people and has been translated into more than 15 different languages for use around the world. It has been researched to show that the results it provides are reliable and valid and it is continually updated through ongoing research to improve its ability to meaningfully identify personality differences.

What do the letters associated with the MBTI instrument mean? The MBTI instrument has four sets of letters:

  • E and I stand for Extraversion and Introversion-indicating whether you get energy from being around people or from time spent alone.
  • S and N stand for Sensing and Intuition-indicating whether you become aware of specific facts and concrete details or prefer to focus on hunches and the big picture.
  • T and F stand for Thinking and Feeling-indicating whether you tend to make decisions based on logical analysis and the principles involved or prefer to decide by considering your values and promoting harmony for the people involved.
  • J and P stand for Judging and Perceiving-indicating whether you prefer your life to be planned and like it when things are decided or prefer to go with the flow and like keeping your options open.

Many individuals have used their understanding of their MBTI type to help them find satisfying jobs, choose academic majors, improve their effectiveness and satisfaction at work, and enhance their interactions and relationships with others.

The MBTI tool does not measure competencies in the way a math test can measure your math skills, for example. None of the MBTI questions is designed to determine how good you are at a particular task. A lot of research exists about what careers people of particular personality types tend to enter, however, as well as about what tasks each personality type tends to enjoy. INTPs and INTJs tend to like the theoretical work of science, for example, and ESFPs and ESFJs tend to enjoy tasks that involve helping others in concrete ways. Thus, the MBTI tool may give you insight into what you enjoy.
