Khan Academy is a not-for-profit educational organization started by Salman Khan in 2008. Our mission is to provide a free, world-class education to anyone, anywhere.
Our online materials cover subjects ranging from math and finance to history and art. With thousands of bite-sized videos, step-by-step problems and instant data, Khan Academy provides a rich and engaging learning experience. You can earn points and badges along the way, and coach others as well.
In addition to our online materials, we are also translating our materials into the world’s most spoken languages, working with schools on innovating how learning is done in the classroom, and running a summer camp to explore project based learning.
