This personality test is based on Jung's classification system, developed by Myers, Briggs, von Franz, and van der Hoop. It is not the official MBTI test (Myers-Briggs Type Indicator® MBTI) or any other similar test instruments, so please do not confuse this. This test is an independent, free development on this website and shows high accuracy in classifying the 16 personality types and their measurements. For each question, mark what you would typically do. Press the start button to begin the test.
