The MBTI® Step II™ personality inventory results in a four-page Step II Profile and/or an eighteen-page Step II Interpretive Report. The details of Step II results show respondents their preferences further detailed into five components, called facets. The results come from responses on Form Q of the MBTI assessment. The Step II report breaks down each preference into facets, which allow deeper analysis of type. "For example," according to the MBTI® Step II Manual, "Extraversion-Introversion encompasses such facets as sociability, activity level, and expressiveness. A different measurement approach to Extraversion-Introversion might focus on a single facet, for example, sociability. In such an approach, the items making up that measure would ask only about the respondent's attitudes or behaviors regarding sociability."

Step II results help define the differences with the 16 types and also provide assistance to people who are having trouble identifying their best-fit type. For example, a woman who prefers Perceiving might be confused because she does not take a Perceiving approach to due dates for tasks. She is more comfortable finishing work well ahead of time, which is more typical of people who prefer Judging. Her Step II results indicate a preference for Judging on that facet, explaining why she may have had doubts about her preference for Perceiving. Her overall preference would remain Perceiving, even though some of the five facets under Perceiving may indicate her preference for decisiveness and closure.

When the Step II™ instrument is given alone, it provides results for a person's four-letter type but also includes the more detailed information on the facets. It can be administered to people who already know their four-letter type who have the desire (or opportunity) to explore their type in more depth. In either case, the MBTI practitioner has the choice of providing respondents with a four-page profile or an eighteen-page interpretive report.
