Today’s most popular method used for personality assessment is a tool called the Myers-Briggs Type Indicator or MBTITM, which is taken by over four million people annually, in over 16 different languages.

Organization development professionals, marriage and family counselors, and psychologists use a variety of assessment tools to determine personality type, how individuals process information and how they relate to one another, handle conflict, behave in a team, make decisions, deal with change, and how they communicate.
