Khan Academy Reports an AI Tutor Experiment: Adding Learning History Modestly Improved Performance on the Next Question

Khan Academy summarized about 20 Khanmigo product experiments conducted between October 2025 and April 2026. The organization says adding recent practice history and prerequisite skills not yet mastered to responses produced a combined 6.1% increase in the rate of independently answering the next question correctly.

This is a company disclosure about its experiments and cannot be treated directly as an independent research finding. It still provides a product metric worth tracking: the student's next independent response.
