Currently the organization maintains its headquarters in the original Gesell Institute building on the campus of Yale University.

Outside of the main office, a group of educators called the National Lecture Staff traverse the United States conducting workshops which teach attendees to administer the Gesell Developmental Observation-Revised(GDO-R) assessment.

[citation needed] It is based on the developmental schedules created by Arnold Gesell which detail the patterns and sequences of child development recorded during his large scale observational studies.
