Nine Types of Temperament Association

Who Are We?

We are the temporary trustees of the basic model that commences with the concepts of “Self-Knowledge and Recognition”, which is the cornerstone of the ancient doctrines, trying to comprehend the “physical”, “psychical”, and “spiritual” aspects of human as a whole by somatopsychospritual holistic point of view.


Nine Types of Temperament Model (NTTM) is a unique and holistic model with ontological, epistemological, theoretical, and methodological concepts and applications. Our association was founded by psychiatrists, educators, neurologists, psychologists, and counselors who came together to develop and disseminate this model.
