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.

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.

The IDI has been rigorously tested and found to possess high cross-cultural validity and reliability. As a result, validity of the IDI is established not through “face” validity, but, rather, far more rigorous psychometric criteria. In other words, a person cannot “just look at the IDI items and determine what it measures or whether it is a valid assessment.”
