At the moment, we are not looking to host partner content. If you are interested in joining the Khan Academy team as a content creator, please view our Careers page for relevant job openings.
We frequently receive new content requests for Khan Academy, but unfortunately, we're not able to accommodate them all. Right now our small team is focused on our core priorities, which are to create content for core academic subject areas spanning K-12.
If you have a request or new ideas for content you want to see, post the Content Requests and Feedback page in the Help Center! Khan Academy is always looking for ways to improve, and the best way to get your idea visibility is by posting in the community forums.
