We are continuing to make the video content available in other languages. Subtitled video content is also available and can be surfaced by selecting the subtitles option just below an English video to see which languages are available. You can also use the filtering tool available at www.khanacademy.org/contribute to view videos that have been subtitled in a particular language (click "Full List" if you'd like to see more tool functionality).
We are first working on making the video content available; in the longer term, we hope to also translate our exercises and dashboard. This effort is largely volunteer driven, in addition to significant partnerships with organizations such as Intel (Spanish and Portuguese) and the Azim Premji Foundation (languages of India). We are always looking for additional organizations and individuals who would like to make Khan Academy more widely available.
To join the translation effort, please visit www.khanacademy.org/contribute for more details and for a full list of languages.
