What is the IDI?


The Intercultural Development Inventory (IDI) helps individuals and teams assess and reflect on stages of cultural competence. The IDI was developed by Dr. Mitchell Hammer and Dr. Milton Bennett as an empirical measurement of cultural competence as conceptualized by Bennett’s Developmental Model of Intercultural Sensitivity (DMIS).

A powerful assessment tool to help individuals and teams assess and reflect on stages of cultural sensitivity

  • A theory-based (not opinion-based) inventory which meets standard scientific criteria for a valid and reliable psychometric instrument
  • A 50 item questionnaire available in 12 languages
  • The IDI is currently being used by over 1,200 Qualified Administrators in over 25 countries

How Does the IDI Assessment Work?

Participants complete a confidential (password accessed) online inventory. A Qualified IDI Administrator creates a graphic profile (for a group or individuals). IDI Administrator explains stages of the Developmental Model of Intercultural Sensitivity (DMIS) which is the theoretical base of the instrument. IDI Administrator provides graphic profile and interpretation. Teams or individuals reflect on results of inventory, strategize for further development and achieve greater understanding of reactions to cultural difference. How much time does it take? Completion of the online inventory approximately 25 minutes. Information session and profile interpretation approximately 1.5 -2 hours. Individual profile interpretation 20-30 minutes. (Optional, but recommended for maximum effectiveness).
