PeerTeach is a data-driven peer tutoring platform for middle school math that was developed through research at Stanford University. It assesses students’ mastery of mathematical concepts, predicts the most effective tutoring pairs within a math class, and then provides scaffolding for peer tutoring. Our mission is to empower every student to grow their leadership, confidence, and love of math while supporting their peers in times of need.
