Intercultural Development Inventory™ 

The Intercultural Development Inventory (IDI) is a powerful tool to help individuals and teams assess and reflect on stages of cultural sensitivity. The (IDI) was developed by Dr. Mitchell Hammer and Dr. Milton Bennett as an empirical measurement of intercultural sensitivity as conceptualized by Bennett’s Developmental Model of Intercultural Sensitivity (DMIS).

The DMIS has been used extensively in intercultural education and training since 1986 as a framework for explaining the reactions of people to cultural difference. The DMIS identifies a set of cognitive structures (or “worldviews”) that act as orientations to cultural difference which move along a developmental scale from stages of ethnocentrism through stages of ethnorelativism. The IDI is a valid, reliable tool to measure an individual’s (or group’s) fundamental worldview orientation to cultural difference from Denial to Adaptation



  • 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 15 languages.

  • The IDI is currently being used by more than 1,500 Qualified Administrators in more than 30 countries.

  • To date, 500,000 individuals have taken the IDI



  • To assess cross-cultural competencies for teams or individuals working in cross-cultural situations.

  • To understand and identify developmental stages of students.

  • To encourage reflection and strategizing for multicultural teams.

  • To determine areas that facilitate, or limit, cross-cultural competence for teams or individuals.

  • To increase self-awareness of intercultural competencies and encourage further development.

  • To establish a language and conceptual framework for discussing intercultural interactions.




The IDI can help respondents to:


  • Understand the developmental stages of intercultural sensitivity through which people move towards greater intercultural effectiveness.

  • Increase self-awareness for each individual respondent.

  • Increase organization-level understanding of intercultural issues.

  • Determine training and educational needs.

  • Evaluate the effectiveness of training, counseling and education endeavors.

  • Improve the intercultural skills of respondents.

  • Prepare to enter a new culture, such as a multinational environment, a new country, or a domestic situation with cultural diversity.


  • Participants complete a confidential (password accessed) online inventory.

  • A Qualified IDI Administrator, will create and provide a graphic profile and interpretation (for a group or individuals).

  • In a Group or Individual debrief session, orientations along the IDI Continuum are explained.

  • Individual Profile Results are private and only shared with the Individual through a one-on-one Debrief Session

  • Individuals will receive a detailed customized Intercultural Development Plan and Action Planning Template for personal development. 

  • Teams or individuals reflect on results of the IDI, strategize for further development and achieve greater understanding of reactions to cultural difference.
