What is the Intercultural Development Inventory (IDI)?

The Intercultural Development Inventory (IDI) is a widely used assessment tool designed to measure an individual's or group's intercultural competence—the ability to understand, appreciate, and effectively interact with people from different cultural backgrounds. The IDI provides insights into how people perceive and respond to cultural differences, helping organizations and individuals identify areas for growth. It is often used in education, business, and nonprofit sectors to guide training and development programs that foster intercultural effectiveness.
