The document summarizes the Keirsey Temperament Sorter (KTS), a personality assessment tool developed in 1978 based on Carl Jung's work. The KTS is used widely in organizations to help people understand their own temperament and how it impacts behaviors, communication, teamwork and decision-making. It measures preferences on four domains - how people are energized, take in information, make decisions, and structure their lives - to determine one of 16 temperament types. Understanding one's type can help with career choices, teamwork, problem-solving and utilizing an organization's human resources.
