Each user has the ability to make this change to their account by using the following steps:

1. Select "My Profile & Settings" in the top right corner dropdown.  This can be accomplished in both learner and administrator views.
2. Under the "Localization" section, click the pencil to edit this section. 
3. Under the "Language" section chose the preferred language.  
4. Click "Save".

Administrators may also change the language for users by editing the user's profile or setting a language as the default language for the whole platform by going into Account --> Profile--> Default Language.

Note:  This setting will not change the language of the course material, therefore, if you expect learners will use a variety of languages, we suggest creating courses in each of these languages and setting up categories to group these courses by language.
