Success with the IDI

See what users of the IDI say about their experience!

“The IDI should be a central component of any in-depth intercultural training, cultural self-awareness program, DEI training, or anti-racism work. It is a valid and reliable tool that allows for individualized training approaches, tailored to each person’s specific needs. Because the IDI presents the stages of intercultural development in a non-judgmental way, it avoids the defensiveness pitfalls of many other approaches to developing cultural self-awareness and skills.”

Ann Gross

Professor Emeritus of Speech Communication, Napa Valley College

“As a global DEI leader, I’ve leveraged several cultural platforms to support an immersive learning approach. However, the IDI outperforms in assisting teams and organizations understand cultural gaps with a customized profile and developmental plan. I will continue to administer the IDI in driving equitable business priorities.”

“The IDI provides a base framework from which to developmentally understand one’s relationship with difference and the strategies we use to navigate them. It’s so sound and clear when used as part of a coaching or intercultural competency growth program that I really don’t use other options.”
