Ei's goal is to create a world in which all children learn with understanding, regardless of their background or curriculum. They achieve this by building products that focus on diagnostic assessment and personalized learning, using a scientific approach to conceptualize, design, and build their platforms. Ei's mission is to discover the Science of Learning and provide teachers with a repository of data and techniques to help children learn better. Their platforms deliver content in the form of questions, activities, games, and videos, using over a billion data points to assess students' learning levels and provide explanations, feedback, and learning inputs for all stakeholders. Ei's work on assessment and learning has already helped create banks of misconceptions and common student errors, which are shared as usable insights with teachers.
