Why Khan Academy works

Personalized learning

Students practice at their own pace, first filling in gaps in their understanding and then accelerating their learning.

Trusted content

Created by experts, Khan Academy's library of trusted, standards-aligned practice and lessons covers math K-12 through early college, grammar, science, history, AP®, SAT®, and more. It's all free for learners and teachers.

Tools to empower teachers

With Khan Academy, teachers can identify gaps in their students' understanding, tailor instruction, and meet the needs of every student.

DISTRICTS

Khan Academy boosts
student learning

In a recent study, students were over twice as likely to meet grade-level standards with Khan Academy. Districts across the country are partnering with us to ensure all their students succeed.

TEACHERS

"I'm finally able to truly differentiate my classroom. This has been priceless for my students' engagement."

DUSTIN FAUTH / 4th grade teacher / Falmouth, MA

We empower teachers to support their entire classroom. 90% of US teachers who have used Khan Academy have found us effective.

LEARNERS AND STUDENTS

You can learn anything.

Build a deep, rock-solid understanding in math, grammar, science, history, SAT®, AP®, and more.

"I come from a poor family. At home it's one room, just a room we live in. When I was a child, I used to fear mathematics. But now, I am in love with mathematics because of Khan Academy."

TOGETHER WE CAN MAKE A DIFFERENCE

Every child deserves the chance to learn.

Across the globe, 617 million children are missing basic math and reading skills. We're a nonprofit delivering the education they need, and we need your help. You can change the course of a child's life.
