The Intercultural Development Inventory® (IDI®) is the premier cross-cultural assessment of intercultural competence that is used by thousands of individuals and organizations to build intercultural competence to achieve international and domestic diversity and inclusion goals and outcomes. IDI research in organizations and educational institutions confirms two central findings when using the IDI:

Interculturally competent behavior occurs at a level supported by the individual’s or group’s underlying orientation as assessed by the IDI.

Training and leadership development efforts at building intercultural competence are more successful when they are based on the individual’s or group’s underlying developmental orientation as assessed by the IDI.

In contrast to many “personal characteristic” instruments, the IDI is a cross-culturally valid, reliable, and generalizable measure of intercultural competence along the validated intercultural development continuum (adapted, based on IDI research, from the DMIS theory developed by Milton Bennett). Further, the IDI has been demonstrated, through research, to have high predictive validity to both bottom-line cross-cultural outcomes in organizations and intercultural goal accomplishments in education.
