IEA General Ethical Guidelines:

The Enneagram can be used by individuals and professionals from a variety of backgrounds, including educators, business consultants, artists, therapists, spiritual directors, and medical professionals; all of whom use it in an increasing range of contexts and applications. Because the Enneagram is such a powerful and profound system for understanding the human character, it is important that those who use the system with others do so in a values-based, ethical manner.

We encourage each professional to use the Enneagram within his or her areas of training and expertise. For example, we expect that business consultants would use the system for organization development, team building, and leadership training; coaches might use it with clients to help them improve their personal and interpersonal effectiveness and work performance. Neither a business consultant nor a coach would typically do psychotherapy with individuals who have serious emotional problems, such therapy being the domain of licensed psychologists and other mental health professionals. Coaches and consultants using the Enneagram should follow the same practices. Likewise, those using the Enneagram in the business arena should have some expertise in business-consulting engagements.
