School counsellors are uniquely equipped to impact school culture due to their expertise in adopting a systemic perspective while facilitating culturally competent services. This study sought to understand the school culture that places importance on developing U.S. students' appreciation for world cultures and emerging global mindsets. The researchers utilized a phenomenological approach to analyze interviews with counsellors working in schools with international missions within the United States. The emergent themes related to counsellors' beliefs, role expectations, and students' international competencies.
