Khan Lab School (KLS) is a non-profit, mastery-based school founded by Salman Khan in 2014 to cultivate his student-centered philosophy in a physical school environment. Khan is also the founder of Khan Academy and author of The One World Schoolhouse (2012), in which he makes the case for mastery-based, mixed-age, and blended learning with a departure from traditional letter grades. Today, the KLS community is bringing that vision to life on its own campus and also sharing knowledge within education more broadly.


KLS believes that young people are capable of far more than society currently recognizes.  Students at KLS embrace this philosophy, as they progress in their unique journeys and experience the meaningful outcomes of mastery learning. Instead of competing against one another, they collaborate and make real contributions in the world around them. Our students are not singularly focused on chasing high marks or piling on AP courses (we don’t have them!). Instead they take agency in their own learning, seek to understand course content, cultivate a range of interests and skills, and demonstrate their achievements in various contexts. Our students are pioneers in every way. They are pioneers of KLS, of mastery-based education, of the Mastery Transcript, and, most importantly, of their own future.


Khan Lab School’s faculty and administrators foster a community of learners who love to learn. We work diligently to ensure consistency in mastery across disciplines, while also maintaining a commitment to meeting students where they are. The quality of learning remains consistently high, even as our lab school regularly reimagines and tests new methods of teaching and learning. Our team is committed to this model, designed to help our community share best practices with educators locally and globally. KLS is a model for innovation in education.


KLS uses a mastery-based learning model, creating the time and space for what matters most. Students are expected to demonstrate an understanding of all competencies and skills identified in a course before moving on, thereby reducing the number of “gaps” in their education. Academic progress in a discipline is decoupled from age, and every student at KLS is assigned to a mixed-age cohort. While the time it takes a student to finish a course may vary, the depth of mastery remains constant. KLS creates space within and beyond the core academics for students to explore their passions. In this space, they further develop their skills and apply their learning within contexts that are meaningful to them--and quite often develop expertise at a far younger age than many would expect. Physical activity, wellness, and creative expression are also central to community life.
