We have three public TED-Ed lesson types:
TED-Ed Originals - Each lesson script is developed by a team of educators and experts, as well as subjected to a rigorous fact-check as part of our production process.
TED Talk Lessons - There is a very selective screening process for TED speakers. If you access the original talk page on TED.com, you can often find the speaker's footnotes and/or recommended further reading lists.
TED-Ed Selects - These are lessons created by TED-Ed users, using an existing video found on YouTube. TED-Ed staff review nominated lessons and feature only a select few.
Additionally, anyone with a TED.com account can create a private lesson on TED-Ed featuring any YouTube video. If someone sends you the direct URL to a lesson they've created that cannot be found by searching the TED-Ed site, please keep in mind that this lesson has not been reviewed by our staff. Its reliability is dependent on the lesson creator.
If you have any concerns about a particular lesson, we always welcome feedback or questions.
