This case study explores how Anglo-American and Asian leaders perceive their performance in a shared leadership team at an international Christian school in Thailand. In-depth interviews were conducted with seven team members to examine the benefits and challenges of collaboration, decision-making, communication, cultural understanding, and the necessary conditions to strengthen team relationships and enhance effectiveness. Study results show that benefits encompass people with different skills and backgrounds, bringing their strengths and perspectives to bear upon the issues the team works on collaboratively, resulting in more accountable decisions. Team members also liaise with multicultural stakeholders and government officials, making their needs known to the team. Challenges include the time it takes to listen to multiple inputs and reach a consensus and miscommunicating and misunderstanding information in intercultural conversations. To strengthen relationships and enhance effectiveness, team members must develop mutual respect, trust, and humility, maintain emotional and spiritual health, resolve relationship conflicts, and have a shared vision and values. The team of Asian and Anglo-Western leaders shares Christian but not cultural values, which determine their leadership styles. When working together, understanding leaders' cultural preferences regarding power distance and individualism-collectivism prevents miscommunication and misunderstanding.Because Asian leaders seem to value status and unequal distribution of power, undergoing intercultural competence training to work on a shared multicultural team would be beneficial.
