MBTI® Step I

The world’s most popular questionnaire for measuring personality Type

The MBTI Step I (Myers-Briggs Type Indicator®) framework provides the basis for lifelong personal development, and improved organisational effectiveness.

The Myers-Briggs Step I assessment

The MBTI Step I framework looks at four areas that determine individual Type. The four areas are:

  • Extraversion (E) – Introversion (I)
    Where you prefer to get or focus your energy
  • Sensing (S) – iNtuition (N)
    The kind of information you prefer to gather and trust
  • Thinking (T) – Feeling (F)
    The process you prefer to use in coming to decisions
  • Judging (J) – Perceiving (P)
    How you prefer to deal with the world around you

How it works: an individual completes the MBTI Step I questionnaire, which covers all of the areas mentioned above. Their answers, along with a feedback session from a qualified practitioner, help the individual to arrive at a four-letter MBTI personality Type – ESTP, for example. Due to the combinations available, there are 16 MBTI personality Types in total.
