Established in the United States in 2006, the portal has been translated into more than 60 languages, with Bulgarian having some of the best content coverage. The initiative in Bulgaria is represented by the “Education Without Backpacks” association.

All of this is freely available to anyone anywhere. That includes distance teaching and learning.

Khan Academy mobile learning app in Bulgarian is the first application of its kind in Bulgaria, offering exercises and lessons across the general education subjects.

Since 2011, thousands of work hours have been invested in the Khan’s Bulgarian version. Even before the establishment of “Education Without Backpacks”, hundreds of volunteers had already  been working on the Bulgarian version – translators, proofreaders, teachers, and experts in various fields. Khan’s Bulgarian version (bg.khanacademy.org) contains about 6,000 translated video lessons (as of 2021), tens of thousands of exercises and tests, as well as articles in Mathematics, Physics, Chemistry, Biology, Computer Science and Programming, Health and Medicine, World History, Music, Philosophy and Critical Thinking; Environmental Science. Tens of thousands users learn in Bulgarian monthly. The platform was recommended by the Ministry of Education and Science to all schools at the beginning of the pandemic in 2020.
