WatchKnow Educational Videos is a companion app to the www.WatchKnow.org website which provides free educational videos for teachers, students, parents, and homeschoolers teaching students in K—12 (USA) or ages 3—18 (international).

The videos are reviewed and approved by teachers for teachers (Kid Safe!) and are placed in 3,000 different categories using a “super” directory with multiple subdirectories. Our Web site is organized as a wiki so teachers and educators can participate in the organization and growth of the WatchKnow video library. Our users have the ability to rate all videos (using a 5-star method) with the result that the best videos are shown first in the list of over 20,000 educational videos. Our teacher-editors also modify video titles and descriptions so relevant videos can be found quickly, tag the videos with an age rating, and indicate the original source of the video.
