Intercultural Development Inventory (IDI)

Intercultural Development Inventory title

The Intercultural Development Inventory (IDI) is a tool for assessing and growing your multicultural competency, based in the Intercultural Development Continuum (IDC). The IDI begins with individual questionnaires, followed by one or more group workshops with a consultant as well as one-to-one meetings with the consultant.

The IDI emphasizes developmental growth and offers paths to engage more deeply and build one’s own intercultural competence. Its developmental approach is “low-judgment” and makes it clear that we all have something to learn. The online UU Institute program Co-Creating Diversity, Inclusion, and Equity in Our Congregations is based on the IDI.

Optimal group sizeCan be used for individuals, and small-to-large groups. The IDI works best with a specific team within a congregation (e.g. staff team, anti-racism team, hospitality team) that is already engaged in the work of anti-racist multicultural transformation.
RecommendationsThe IDI is compatible with the UUA's Mosaic Platform but does not always emphasize an anti-racist power analysis. When you use it, share this video from Rev. Julica Hermann DeLaFuente as a supplement that brings together the IDI and anti-racist power analysis.
How to access facilitatorsTo connect with Unitarian Universalist qualified administrators and facilitators of the IDI, contact the UUA MidAmerica Region, The IDI administrators/facilitators are required to be trained and certified by the IDI organization.
FormatOnline inventory, workbooks, 1:1 meetings, group workshops
