Khan Academy

Khan Academy ( is the world’s biggest large-scale education portal. Moreover, free of charge! The website features nearly 10,000 video lessons and over  100,000 interactive exercises. They are embedded in a learning social network, as teachers gain access to useful information about classroom management. The lessons mostly cover the school subjects from the 1st to the 12th grade, preparatory modules from the university education and many lessons of general cultural nature. Khan Academy has about 72 million users in over 190 countries. Among the founders of the platform are the Bill and Melinda Gates Foundation, Google and many others. Founded in the United States in 2006, the portal is translated into more than 100 languages, with Bulgarian language being one of the most translated ones. Behind the initiative in Bulgaria stands the “Education without Backpacks” Association.

All this is free of charge and accessible to everyone in the world.


Since 2011, thousands of hours of work have been invested by hundreds of volunteer translators, editors, teachers and specialists from various other fields, as well as several thousand dollars of donated personal funds. Thanks to these efforts, a test version of the Khan Academy in Bulgarian (, is available since the autumn of 2014, in which over 3000 translated videos are available, visited by thousands of users monthly. In addition, we have dubbed over 300 video lessons in mathematics, and until the middle of 2018, a dubbing of a few hundred clips is planned.

From the autumn of 2017 the Bulgarian team already manage the uploading of new content itself, guaranteeing a stable version with fully translated content. In practice, this means that on the Bulgarian version are published only those topics from the Khan Academy, which are translated at 100%. There will be no irritating phrases or entire exercises in English, among the otherwise translated into Bulgarian content.

From May 2017, Education without Backpacks is working hard on completing the translations, edits, dubbings, and expert review in relation to the Bulgarian curriculum in Mathematics and Computer Science – made possible by the main partner of the association the America for Bulgaria Foundation.

Meanwhile, all biology videos have already been translated and available at with the kind support of the Public Board of TELUS International Europe.

The end of 2017 commemorated also a successfully completed project with the Sofia Municipality under the Europe 2017 Program for pilot use of Khan Academy in two Sofia schools. At the end of the year, we also concluded our first contracts for training in a school for work with the Khan Academy, developing digital competences and managing the classroom.

In 2018, we continue to translate, edit and dub new content from the Khan Academy, with popularization of the platform among teachers, pupils and parents: for access to quality education at world level for even more Bulgarian children!
