Temperament Tests for You 
Wednesday October 15, 2003 by Hal
I’ve often had to explain the difference between temperament and personality - at least from my point of view and experience.
Your temperament is that basic set of behaviors and ways of thinking you were born with. This is the entire premise behind the Meyers-Briggs and DiSC tests. This will indicate whether you are outgoing or introverted, prone to anger or criticism or anxiety, and it cannot be changed.
It can, however, be modified. Personality is the temperament modified by life. Your personality is the sum total of your experiences on top of your temperament.
You can find a couple of pretty good free temperment tests here and here. My indepth article on temperament is on my other blog - I’m Gonna Keep on Lookin’ - here.
