Everything DiSC profiles and supporting materials are available in many languages as well as English. This means that respondents can not only have their report produced in their first language, but also take the self-assessment in it as well. Additional reports, such as Facilitator Reports, can be generated in English irrespective of the language the original report was produced in.
The table at the link below shows the current availability, with new language support being added regularly.
