Policy, systems, and environmental (PSE) change interventions are a key part of comprehensive nutrition and health education. Although Extension educators find value in PSE approaches and report being involved in PSE work, many still indicate a lack of understanding regarding PSE approaches. We describe a unique multistate training designed to increase Extension educators' understanding, skills, and capacity related to implementing PSE change interventions. Data demonstrating success of the training are presented. Additionally, best practices for others wishing to create similar multistate programs conclude the article.
