The Subject-Object Interview Course

What is the Subject-Object Interview?
The Subject-Object Interview (SOI) is a reliable and finely-tuned instrument designed to explore and identify the complexity of a person's meaning-making and current position on the developmental continuum of adulthood as described by constructive-developmental theory¹. Seen as the gold standard of assessments, the SOI is acknowledged as "theoretically the most elegant, and methodologically the most differentiated, of the theories and measures"² of adult development.

The Subject-Object Interview Course
Our interactive approach to learning to use the Subject-Object Interview combined with an individual, guided mentoring certification process is new in the field. Our focus is to provide a learner-centered context in which you can develop the expertise and confidence you need to use the SOI successfully in your work. You will learn the SOI with its foremost expert and master trainer and certifier, Dr. Nancy Popp. Dr. Popp has been applying constructive-developmental theory in both research and practice since the early 1980s when she began her work with Dr. Robert Kegan at Harvard.
The learning and experience gained through your participation in this course will give you sufficient background to start engaging in the field of adult development. Whether or not you meet the criteria for becoming a SOI Reliable Scorer at this time, you will have access to our expert, reliable scoring services and support. This access allows you to immediately put Subject-Object Interviews "to work" in your practice or research.
