According to Keirsey Temperament Theory, there are four basic temperament groups which describe human behavior. Keirsey’s four temperaments are referred to as Artisans™, Guardians™, Rationals™ and Idealists™. These four temperaments can be further subdivided, often referred to as “Character Types”. There are four types of Artisans, four types of Guardians, four types of Rationals, and four types of Idealists.

Artisan – Promoter, Crafter, Performer, Composer

Guardian – Supervisor, Inspector, Provider, Protector

Rational – Fieldmarshal, Mastermind, Inventor, Architect

Idealist – Teacher, Counselor, Champion, Healer

The questions in the KTS®-II are designed to sort between four dichotomous pairs of preferences, leading to results which reveal a person’s temperament and character type. The four preference scales measure a respondent’s preference for the following:

Extroversion – (Expressive)
Sensing – (Observant)
Thinking – (Tough-Minded)
Judging – (Scheduled)

Introversion – (Attentive)
Intuiting – (Introspective)
Feeling – (Friendly)
Perceiving – (Probing)
