Videos

All of our curriculum incorporates videos hosted on YouTube, though many schools block YouTube for students. In the event your school's network blocks YouTube, Code.org will default to a fallback video player, which requires Flash player. Chrome, iOS, and Android do not require extra software to play videos.

You can test your browser's settings to see if YouTube is blocked and to verify that fallback video player will work for your classroom at code.org/educate/IT

 

G-Suite, Google Apps Restrictions on YouTube videos 

If you're a G-suite administrator, be sure to check what your restriction settings are for YouTube.  If you have specified the "Strict Restricted YouTube Access" setting or if you see messages stating 'this video has been restricted', you can add our channel to the approved list of channels.  See this guide from Google to learn about how to add our channel to the approved list.  You can also see this guide to learn more about different settings and which is best for your classroom.   

If you are experiencing issues with videos in your classroom, contact us at support@code.org
