Khan Academy's AI tutor Khanmigo has reached 5 million active student users, with a rigorous study showing students using the tool improved test scores by 14% more than a control group over a single semester.
Efficacy Study
The randomized controlled trial covered 12,000 students across 200 schools in 32 states, making it the largest study of AI tutoring effectiveness to date.
- Math proficiency improvement: 14% greater than control group
- Writing quality scores: 11% improvement over control
- Student engagement: 23% more time spent on practice problems
- Teacher time savings: 5 hours per week on grading and personalized feedback
- Effect was strongest for students performing below grade level
Access and Equity
Khan Academy has secured $120 million in philanthropic funding to provide Khanmigo free to Title I schools serving low-income communities. The AI tutor provides the kind of personalized attention that private tutoring offers at $50-$100/hour, potentially narrowing achievement gaps driven by income inequality in education access.
