MOUNTAIN VIEW, Calif., Dec. 13–CPP, Inc. (www.cpp.com), publisher of the Myers-Briggs Type Indicator® (MBTI®) assessment, is pleased to announce that HR Magazine has named MBTI co-creator Isabel Briggs Myers one of the 50 people who have most significantly changed the face of human resource management. Inclusion in this prestigious list, which also names Peter Drucker, Jack Welch, Tom Peters, and Lyndon Johnson, is a great honor. “The Myers-Briggs® assessment has had a tremendous impact. Isabel Briggs Myers made it her life’s work to help people learn more about themselves and better understand others. We are thrilled that HR Magazine and its readers have chosen to honor this outstanding woman,” said Maria Patrick, Co-President of CPP.

The MBTI assessment has been the personality assessment of choice for over 50 years and is taken by more than 2 million people each year. Created in the 1940s and refined during the 1950s, the MBTI assessment is based on Carl Jung’s theory of psychological types. It sorts people’s personalities into one of 16 four-letter types based on their preferences on four dichotomies: Extraversion–Introversion, Sensing–Intuition, Thinking–Feeling, and Judging–Perceiving. CPP has been the exclusive publisher of the MBTI assessment since 1975.

Used by 87 of the Fortune 100 companies, the MBTI assessment is used to enhance communication, team building, and leadership development in the workplace; give professionals and students insight into better career choices; ease retirees into the next phase of their lives; and help couples understand differences in counseling. A large and loyal community of MBTI proponents has evolved—meeting on the Internet and in person—to discuss type theory and its applications in their professional and personal lives.

As part of its ongoing commitment to improve the MBTI assessment, CPP revised it in 1998 using item response theory (IRT), a cutting-edge approach to testing. (IRT is the same technology used in revisions of the SAT, GRE, and GMAT standardized tests.) The revised MBTI assessment, known as Form M, is more accurate than ever, with greater reliability and validity.
