ClassDojo was founded in 2011 by Sam Chaudhary and Liam Don, who met while studying at the British equivalent of a teaching college. They created the app to help teachers manage classroom behavior and communicate with parents — two everyday challenges that existing tools weren’t solving well.
The app centers around a simple, cheerful interface where each student is represented by a customizable monster avatar. Teachers award or deduct points for behaviors like participation, teamwork, or being off-task. This real-time feedback system gives students visible recognition and helps teachers track behavioral patterns over time. The gamified approach makes classroom management feel positive rather than punitive.
Communication features are equally important to ClassDojo’s success. Teachers can share photos, videos, and updates from the classroom through a feed that parents access on their phones. Direct messaging between teachers and parents, translated automatically into 35+ languages, has made ClassDojo a lifeline for schools with diverse, multilingual communities.
ClassDojo is free for teachers and parents, which has driven massive adoption — the platform is used in 95% of K-8 schools in the United States and in 180 countries. The company generates revenue through ClassDojo Plus, a premium subscription that gives parents additional features like full access to their child’s portfolio and learning content. Beyond behavior tracking, ClassDojo has expanded into social-emotional learning content and student portfolios where kids showcase their work.
