This is an extended version of the MBTI® test, establishing your MBTI® types and adding up your preferences is only the first step towards truly understanding your behaviour and reactions. Taking the MBTI® Step II will provide more specific clarification and insights and you will learn how people with different preferences interact with each other. Besides, you will also learn how people with same preferences and even types behave differently. This second stage provides four letter types (see below) and looks at five characteristics associated with each preference. Step II provides additional depth and clarification within each of the four original MBTI® preference pairs, or dichotomies.
