About Us

ClassDojo is on a mission to help every teacher create an incredible classroom

With ClassDojo, we’re finally able to do the work that inspired us to become teachers in the first place. We have BIG dreams for our students and ourselves. And for the first time, I feel like I’m making them happen.

ClassDojo's Mission

To give teachers, parents, and students the power to create incredible classrooms

At ClassDojo, we want to transform education for every kid in the world. To do this – and do it soon – we have a simple plan: connect teachers, parents, and students in every classroom, and work with them every day to bring the best ideas into their classrooms.

It's not about creating an “ideal” classroom, a one-size-fits-all model that everyone must fit, because there's no such thing. Instead, we believe that teachers, parents and students should have the power to create an incredible classroom that is best for them. And, we believe that when you give good people simple ways to do the right things, amazing things will happen.

That's how we believe we can transform education. Together. By helping every teacher, parent, and student in the world create an incredible classroom all their own.

What is ClassDojo?

ClassDojo is a communication app for the classroom. It connects teachers, parents, and students who use it to share photos, videos, and messages through the school day. They use ClassDojo to work together as a team, share in the classroom experience, and bring big ideas to life in their classrooms and homes.

ClassDojo is so cool! There are so many things we learn and do at school that we wish our parents could see, and now they can! Teachers, students and our parents all work together to make our time in school worth every minute.

Product overview


Classroom is where teachers and students build their classroom culture. They choose skills and values – things like creativity or teamwork – and share feedback on progress with each other. Classroom is the simplest way for teachers and students to build an incredible classroom culture together.


Messages allow teachers, parents, and school leaders to instantly message each other, without needing to share phone numbers or contact details. Messages can be translated into 35 different languages, and "Quiet Hours" lets teachers set away times so parents know when they are not available.


Stories are instantly updating streams of pictures and videos from the school day. Every class, school, and student has their own Story, all of which are shared home with parents. School Story helps school leaders to share with all families connected to their school, Class Story helps teachers to share with all families connected to their class, and Student Stories helps students to create their own story: a timeline – or portfolio – of what they've learned.

Original Content: Big Ideas
