About the MBTI® Step III Work

The journey taken to develop the MBTI® Step III instrument and report has proven to be both a long and rewarding one. It began early in Isabel Myers' career when she wanted to help people develop their individual type as completely as possible, and continues today with her belief that


"...understanding your patterns of perception and judgment can make your perceptions clearer, your judgments sounder, and your life closer to your heart's desire."


The current forms of the MBTI assessment (administered only by trained professionals) are designed to assess different aspects of psychological type:

  • MBTI Step I™ results indicate preferences for one of the 16 types
  • MBTI Step II™ results fulfill Isabel Myers' plan to provide people with individualized type reports that reflect the distinctive ways they express their type preferences
  • MBTI Step III analysis actualizes Myers' goal of helping people use their natural types as effectively as possible

The Step III assessment is scored in a way that shows the respondent's current ways of using perception and judgment, and the likely effectiveness of those uses, which is assumed to be evidence of type development.

In-depth sessions with the trained Step III professional helps the client explore identified issues and gain the necessary insight for becoming more effective in the natural use of their type.

Suggestions and statements included in the highly individualized MBTI® Step III Interpretive Report are designed to enhance one's type development through dialog with a trained counselor or coach. As with all aspects of the MBTI instrument, Step III scoring is interpreted within the context of healthy personality and requires the respondent's verification of their results.

Step III co-author Naomi Quenk says, "The MBTI® Step III Interpretive Report serves as a unique catalyst for meaningful conversation between the client and counselor. Dialogue is the centerpiece of the Step III process. It provides a rich and unique experience for those individuals who have the opportunity to work with a trained Step III professional."
