A growing body of research indicates the impact that Khan Academy’s personalized mastery learning has on driving learning outcomes.

Learning outcomes exceed typical growth.


Students perform better than expected on district established targets.

In partnership with Long Beach Unified School District in Southern California, 5,348 middle school mathematics students used Khan Academy integrated into instruction for 1 class period per week. Students who used Khan gained an additional 22 points (.20 ES) on the Smarter Balanced Mathematics Assessment scale score. The district indicates this is roughly 2x the district target versus those who did not use Khan Academy.

“I love that Khan Academy shows you your errors. It really helped me in understanding words in context; it really broke it down for me. With the PSAT/NMSQT score I doubted myself, but my teachers showed me with Khan Academy I could do it. If it wasn’t for Khan Academy, I wouldn’t have access to SAT practice at all. It’s a godsend!”

—Tatiana, a senior at Oak Ridge High School in Orlando, Florida
