Keirsey Temperament Sorter

The Keirsey Temperament Sorter (KTS) is a self-assessed personality questionnaire designed to help people better understand themselves and others. It was first introduced in the book Please Understand Me. It is one of the most widely used personality assessments in the world, and its user base consists of major employers including Bank of America, Allstate, the U.S. Air Force, IBM, 7-Eleven, Safeco, AT&T, and Coca-Cola. The KTS is closely associated with the Myers-Briggs Type Indicator (MBTI); however, there are significant practical and theoretical differences between the two personality questionnaires and their associated different descriptions.
