Impact
Every skill counts.
Learning doesn’t happen all at once. It accumulates. Practice on Khan Academy builds skills. Skills build measurable academic growth.
Skill by skill, gains add up
Each additional skill mastered is associated with measurable gains.
Implementation amplifies impact as seen in a randomized controlled trial.
Khan Academy District students are 6X more likely to get 60+ skills a year.
National, peer-reviewed research published in PNAS
Growth builds one skill at a time.
A study published in PNAS, one of the world’s leading scientific journals, analyzed 200,000+ students and found that mastering more skills on Khan Academy corresponded with higher state math scores.
A growing body of evidence
One study can show promise. Many studies show a pattern: Khan Academy practice supports academic growth.
What strong evidence looks like
In high-stakes decisions, research should be:
- Independent — reviewed by academic peers
- Large-scale — not a small pilot or selective sample
- Causal — not just usage correlations
- Transparent — publicly available and replicable
Khan Academy’s research meets these standards — because districts, teachers, and our philanthropic funders deserve clarity.
Khan Academy District partners master more skills
Students in Khan Academy Districts are 6× more likely to reach recommended practice levels. That consistency allows per-skill gains to compound across classrooms, schools, and entire districts.
Built for learning. Not for profit.
As a nonprofit, we measure success by one thing: student learning. If it doesn’t improve outcomes, it doesn’t belong at Khan Academy.
