There are currently four distinct forms of the MBTI® questionnaire. Each one is different in its use and scoring.
Form M (93 items).The current standard form of the MBTI® assessment and is scored for four-letter type and the preference clarity indexes. Online administration and scoring is available through the publisher, The Myers-Briggs Company. Computer or template scoring is also available.
Form M self-scorable (93 items). The current standard self-scorable form and is scored for four-letter type. The preference clarity indexes may also be calculated. It is hand-scored by the individual taking the Indicator, or by the professional.
Step II™ Form Q (144 items).Used to generate a four-letter type and scores on twenty facet scales, with five facets in each of the four primary MBTI dichotomies. The facet results highlight individual differences within type. Used when in-depth individual feedback is needed (e.g., coaching, counseling, executive development, relationship counseling).
Step III™ (222 items). Designed for anyone who wants to increase awareness about the specific and unique ways they use their type in making life choices. In-depth sessions with a trained Step III professional help the client gain insight necessary for becoming more effective in the natural use of their type. The MBTI® Step III™ Interpretive Report is written directly to the client using "non-type" language. The counselor helps the client process the statements generated to address their current level of self-confidence, approach to difficulties, sources of enjoyment, and more. The Step III instrument and Interpretive Report are available for purchase and use only by professionals who have successfully completed the MBTI® Step III™ Certification Program.
