A foundation for life-long development


By defining personality type, the Myers-Briggs Type Indicator® (MBTI®) tool builds a robust foundation for life-long personal and professional development. It provides a constructive, flexible and liberating framework for understanding individual differences and strengths.


What is the MBTI®?


    • 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 in sales training, sales, product development, service process, marketing and organisational development every year for the last 12 years.

The MBTI® tool: personality type revealed


The MBTI® instrument is the best known and most trusted personality assessment on the market, and The Myers-Briggs Company is its exclusive distributor. Far more than just personality tests, MBTI® Step I and Step II provide a constructive, flexible framework that can be applied to all areas of human interaction and personal development. The MBTI® profile reveals how we see and interact with the world, giving insight into our motivation and the motivation of others. This provides a strong foundation for personal growth and development, underpinning enhanced personal effectiveness.


  • MBTI® Step I identifies personality type, made up of four basic preferences, and provides a positive framework to explain how we interact with the world and each other.
  • MBTI® Step II drills into the detail of Step I preferences, providing insight into the unique way in which we express our personality type.


Starting with an understanding of MBTI® type, the MBTI® framework supports a far-reaching and lifelong development journey which embraces many common challenges in the workplace, and outside it.

Uncovering the DNA of personality Type

MBTI® Step II goes beyond the Step I framework to reveal the unique individual behind each MBTI® personality profile. It acts as a catalyst for enhancing personal and business results by providing focused insight to support development planning.


What is MBTI® Step II?


MBTI® Step II is a Myers-Briggs® questionnaire that hits at the heart of who someone is by tapping into the facets within each Step I Type preference. It can help you to understand the DNA of an individual’s personality, revealing what makes them different to others of the same Step I Type, and similar to those with a different MBTI® Type. The result is a highly personalised profile and development plan that is perfect for coaching, action planning and building cohesive teams.


MBTI® Step II: key features

  • Examines the subtleties in the expression of MBTI® Step I type for different people
  • Uses five behavioural facets to explore each of the four Step I dichotomies
  • Pinpoints the uniqueness within each profile
  • Provides development actions across a range of important individual issues
  • Offers easy administration via Elevate®


The Myers-Briggs® tool: the power of detail


Using the insights of MBTI® Step I framework as its starting point, Step II explores these broad-brush revelations in greater detail.

It works by drilling down into each of the preference pairs (E-I, S-N, T-F, and J-P) to reveal results on five supplementary facets of personality for each. It highlights how these fit with the overall Step I type, and where there are inconsistencies that can explain interpersonal challenges. Step II has the power to help people see in great detail where their points of compatibility and potential discord lie, providing a convincing and resonant framework for teams and individuals at all levels.

The MBTI® Step II Interpretive Report uses a graphical format to display the results, guaranteed to enlighten, inspire and challenge the individual.


How do I buy the MBTI® Step II tool?


In order to use and buy the MBTI® Step II tool, you must first be qualified to use the Step I instrument - via one of The Myers-Briggs Company's MBTI® certification programs or through another provider.
