Language Courses
Duolingo's language courses are created and maintained in the Incubator by volunteers and language experts with the assistance of staff.[1] Some of these courses are also a result of a partnership between Duolingo and organizations such as the Peace Corps[2].

A listing of all available and in-development courses can be found at the Incubator website. Course information can also be found on the courses page and in the course list, though these may not include all courses or be completely up-to-date. 

StatisticsEdit

The following are statistics related to the courses currently in the incubator. A description of what each specific course phase means can be found here.
