Welcome to the Keirsey Jung Personality Test. This free personality test uniquely combines two powerful systems for evaluating personality type – David Keirsey's Temperaments and Jungian Cognitive Functions. It is based on research originally conducted by Carl Jung in early 1900s that has been enhanced and built upon by other personality type researchers, practitioners and experts over the past 100 years. You’ll be presented with a series of questions for which you will need to provide the answer that is most like you and the answer that is least like you. In taking the test, remember to read the question at the top before answering. There are no wrong answers. The test is simply designed to measure your preferences. Don’t overthink and go with your initial instinctive response to the questions vs. answering how you think you should answer or based on what others might think. After completing the test, you will receive a report outlining your temperament, your four-letter type, the order in which you prefer using your cognitive functions, and a link to a detailed description and videos that provide further information about your personality type.
