Khan Academy’s Path to Customized Experimentation with GrowthBook

Khan Academy needed a feature flag and A/B testing framework secure enough to protect student data, fast enough to not affect performance, and flexible enough for the education platform’s complex testing requirements. In GrowthBook, they found a high performance, secure, and customizable solution.

Khan Academy leveraged GrowthBook’s feature flag functionality to toggle features on an off based on individual attributes, like classroom tags or student districts. This functionality alone proved to be a powerful tool for streamlining their ability to deploy product updates faster. Tailoring the attributes beyond just percentage-based rollouts enabled them to run more conclusive experiments that help them optimize their product for students and teachers around the world.

Khan Academy rapidly adopted GrowthBook, quickly integrating the platform seamlessly across their website, backend, and mobile apps. With GrowthBook’s customization options, they could measure learning outcomes effectively and ensure data privacy. The static settings object model simplified their processes, resulting in an improved user experience without performance impacts.
