In accordance with an embodiment of the present invention, there is provided a plurality of color-coded cards and representing four personality styles and a set of two cards representing the Extraversion-Introversion scale of Carl Jung. On each set of two (2) cards, there is one that lists twenty (20) characteristics of the particular style associated with that card on a plurality of removable strips. The other card in the set of two (2) has a blank side to place the removable strips that characterize each participant. On the reverse side of this card is printed the workplace environment that most appeals to a person of this particular style. Each card has a place for a simple score, (i.e. a simple sum of the characteristics chosen). The color-coded cards are ordered numerically. The Extravert-Introvert (E-I) card is also scored. Participants are asked to place color-coded dots representing each participant's particular order of styles on their nametags. The first style represents a participant's dominant personality style. The combination of all four styles with the Extraversion-Introversion components represents the participant's personality temperament or profile.
