ClassDojo[3] is an educational technology company.[4][5] It connects primary school teachers, students and families through communication features, such as a feed for photos and videos from the school day,[6][7] and messaging that can be translated into more than 35 languages.[8][9] It also enables teachers to note feedback on students' skills and creates a portfolio for students, so that families can be aware of school activities outside of meeting with teachers.[10][11]
According to ClassDojo, its app is used by teachers, children and families in 95% of pre-kindergarten through eighth grade schools in the United States, as well in a further 180 countries.[1][12][2] ClassDojo is an alum of Y Combinator's Ed-tech division, and was launched in August 2011 by Sam Chaudhary and Liam Don from the ImagineK12 education seed accelerator.[13]
