“Our school district has found Khan Academy to be a game changer as we strive to improve equity, access and college readiness. Collectively, our students have achieved one of the nation’s highest participation rates in Khan Academy because they and their families quickly recognized the value of Khan’s customized SAT practice lessons, which are based upon each student’s performance in math and English. Through this targeted approach, Khan helps to level the playing field and remove barriers for students as they prepare for success in college.”

“Now as Khan Academy has expanded, it has problems mapped to pretty much every standard that I covered during class, and I know that I can trust those problems to be good, rich problems.”
Teacher in Anaheim Union High School District
“I feel more confident because if I have a worksheet in a normal class, I turn it in but I don't know if I did right or wrong until the teacher goes over it. But in Khan Academy, I do problems and then I can see if I'm wrong or right...it makes it more simple and easier and a bit fun, I would say!”
High School freshman
“I have found Khan Academy to be a great option for homework. It has freed up valuable class time. Instead of making copies, correcting paperwork, and returning paperwork, I have more time to spend with my students teaching them how to write. Lots of benefits.”
