How many letters are on a Myers- Briggs personaluty type quiz?

The Myers-Briggs personality type consists of four letters. There are eight personality types, and four letters represent each individual. An individual takes a test and then is marked by preferences for either Extroverted (E) or Introverted (I), Sensing (S) or Intuitive (N), Thinking (T) or Feeling (F), and focused on Perception (P) or Judgment (J). Thus, each person comes out with a 4-letter type, such as INTP, or ESFJ.
