Partnerships can enhance individual and organizational success through more effective problem solving and improved adaptation to change. Learning is often required for successful collaboration that may transform the partners. This article discusses a study that explored learning in Extension staff partnerships that transform the individual, the partnership, and the organization. Three types of learning and eight types of transformative learning are identified. Conditions that promoted transformative learning in successful partnerships included strong partner facilitation, critical reflection, critical events, partner difference bridged by common purpose, and independence with interdependence. Recommendations for nurturing transforming Extension staff partnerships are shared.
