All BIA users should be able to change their language through the Settings feature near the bottom of the left menu.
Once you toggle the Settings menu, select the User Profile second item option.
If you registered for the B Impact Assessment as part of a partner program, you may have limited language availability depending on your partner's settings.
If your partner only supports 1 language (i.e. English), you cannot change your language (the Language drop down WILL NOT appear).
If your partner supports more than 1 language (i.e. English, Spanish, Italian), you can change your language to one of the languages available in your User Profile.
