Description of the Test
The MBTI Step II is a self-report type-based measure of personality that builds upon the foundation laid by the MBTI Step I. Whereas Step I classifies test takers according to their preferences against four dichotomies (Extraversion vs Introversion, Sensing vs Intuition, Thinking vs Feeling, and Judging vs Perceiving), Step II expands upon this by also examining 20 facet-level scales that underlie these four preferences. This provides substantially more information about how a respondent exercises their basic type preferences than Step I and allows greater differentiation between individuals with the same type. This also provides a more personalised profile in addition to the core type findings, and a development plan that is useful in coaching, career counselling, and building better teams.
The 20 facets are:
E-I facet scales:
S-N facet scales:
T-F facet scales:
J-P facet scales:

Step II should not be viewed as an ‘add-on’ to Step I. Rather, it is a standalone tool in its own right. It contains all of Step I’s items, and 78 additional items, bringing the total number of items to 166. As such, it is a somewhat longer tool than Step I.
Step II is an entirely online tool. It is administered via an online assessment platform, and scores and feedback are generated automatically. Once a test taker (or team of test takers) has completed the tool, the user can download a report of their preferences and facet scale scores for feedback. Additionally, the system can generate individual and team ‘Typies’, graphical representations of an individual or team’s overall profile, which provides a simple summary of their personality.
An interesting feature of MBTI Step II is its use of IRT Item Response Theory (IRT), which allows for a more accurate form of scoring. Facet scores are centred around a midpoint of 0, and the strength of preference is arranged on a 5-point scale either side. Scores to the left indicate a preference for facets associated with Extraversion, Sensing, Thinking and Judging (the first part of the dichotomy), and facet scores to the right with the other side of the dichotomy. Scores are considered to be ‘in-preference’ when they are in the same direction as the person’s underlying best-fit Step I preference. Scores are considered ‘out-of-preference’ when a facet score is not in the same direction as the Step I preference, for example, an individual with a preference for Sensing but a preference of 4 for Imaginative (which is more indicative of Intuition).
