The Khan Academy Review

Khan Academy is a non-profit educational organization created in 2006 by educator Salman Khan with a goal of creating a set of online tools that help educate students from kindergarten to high school. The organization produces short lectures in the form of YouTube videos. Its website also includes supplementary practice exercises and materials for educators.

All resources are available to users of the website. The website and its content are provided mainly in English, but are also available in other languages, including Spanish, Portuguese, Italian, Russian, Chinese, Turkish, French, Bengali, Hindi, and German. 


Khan Academy is a 501(c)(3) nonprofit organization, mostly funded by donations coming from philanthropic organizations. In 2010, Google donated $2 million for creating new courses and translating content into other languages, as part of their Project 10100 program. In 2013, Carlos Slim from the Carlos Slim Foundation in Mexico, made a donation for creating Spanish versions of videos. In 2015, AT&T contributed $2.25 million to Khan Academy for mobile versions of the content accessible through apps.

According to Khan Academy’s filings with the U.S. Internal Revenue Service, Salman Khan’s annual salary in 2015 was -800,000. Salman Khan has received over $350,000 in annual compensation from Khan Academy since 2011. In 2013, former President and COO Shantanu Sinha also received over $375,000 in compensation.


Khan Academy’s website aims to provide a personalized learning experience, mainly built on the videos which are hosted on YouTube. The website is meant to be used as a supplement to its videos, because it includes other features such as progress tracking, practice exercises, and teaching tools. The material can also be accessed through mobile applications.

The videos show a recording of drawings on an electronic blackboard, which are similar to the style of a teacher giving a lecture. The narrator describes each drawing and how they relate to the material being taught. Nonprofit groups have distributed offline versions of the videos to rural areas in Asia, Latin America, and Africa. Videos range from all subjects covered in school and for all grades, Kindergarten to High School.

Khan Academy videos have been translated into many of the world’s most popular languages, with many videos dubbed into the world’s top spoken languages. There are close to 20,000 subtitle translations available. Khan Academy offers its platform in 5 languages: English (en), Spanish (es), Portuguese (pt), Turkish (tr), French (fr) and Bengali (bn).

It also provides online courses for preparing for standardized tests, including the khan academy SAT and MCAT.

In July of 2017, Khan Academy became the official practice partner for the College Board’s Advanced Placement. They plan to release LSAT preparation by 2018, (Source-wikipedia).
