Myers-Briggs Type Indicator®

“The MBTI® instrument is close to the silver bullet for business. It lets you align the key elements… customers, staff and management. We have used the MBTI® instrument at Westfund Health in sales training, sales, product development, service process, marketing and organisational development every year for the last 12 years.”

- Grahame Danaher, CEO, Westfund Health


Over the past 70 years, the Myers-Briggs Type Indicator® (MBTI®) instrument has helped millions of individuals throughout the world gain awareness about themselves and how they interact with others. The MBTI® instrument enables personal transformation by giving people a powerful tool for improving how they communicate, learn and work.

In developing the MBTI® instrument, Isabel Briggs Myers and her mother, Katharine Briggs, aimed to make Carl Jung’s theory of psychological type understandable and useful in people’s everyday lives.

The essence of the theory is that much seemingly random variation in behaviour is actually quite orderly and consistent, owing to basic differences in the ways individuals are oriented toward the external world, take in information and draw conclusions about what they perceive.

Please take a moment to explore the 4 dichotomies that make up the MBTI® instrument.

Today, the MBTI® instrument is the most widely used personality assessment in the world. More than 2 million assessments are administered to individuals annually - including employees of many Fortune 500 companies. Organisations have selected it as the personality instrument of choice across their training and development programs because it provides a common language for appreciating interpersonal differences.


Certification in the MBTI® Instrument

The MBTI® instrument is what we call ‘Restricted’ and you need to be trained and certified to access and use it. This ensures that the instrument is used for the purpose for which it was designed and that it is being administered and interpreted correctly.

We offer a Certification Program that will qualify you in the professional and ethical administration of the MBTI® instrument and upon successful completion of the program, you will gain a certificate of qualification to purchase and use both the instrument and its reports.


Validity & Reliability

The MBTI® instrument demonstrates some of the highest levels of consistency and reliability of any personality assessment product. Many years of rigorous testing and use of the most up-to-date psychometric tools, such as item response theory  (IRT) for both scoring and item selection, ensures that all MBTI® forms are of the highest quality and value.

The MBTI® Manual contains more than 400 pages of technical and statistical data on the construction and reliability of the MBTI® instrument.

We are also pleased to be able to bring to you these newly released Technical Briefs for MBTI®Form M and Form Q Assessments with Australian and New Zealand samples. The Technical Briefs summarise the measurement properties of both the MBTI® Form M and Form Q, examining the reliability; reporting on type distribution, and providing comparisons with the US National Representative Sample (NRS)
