Association for Psychological Type International

The Association for Psychological Type International (APTi), founded in 1979, is an international membership organization open to any individual interested in personality type. APTi Members come from a variety of backgrounds and professions including business and industry, organizational development, religion, education, psychotherapy, and counseling. Members seek to extend the development, research, applications and ethical use of type theory. APTi is a 501(c)(3) tax-exempt organization.

APTi is undergoing a few changes. We are transforming our organization from a professional association model to a grassroots community model. We will no longer have office staff so we ask that you give us a little time after sending in a communication. We promise we will get back to you in a timely manner with the information you are seeking. Contact us at [email protected].

Our new mailing address is:

PO Box 4538
Itasca, IL 60143
