Edfinity is an NSF-supported (Awards# 1646935, 1758301, 1943530), next-generation homework and assessment platform in use at over 350 institutions including some of the largest public and private institutions. The Edfinity team comprises successful educators, researchers and entrepreneurs with decades of research-backed experience. Their past efforts are the subject of four Harvard Business School case studies. Edfinity is “textbook-agnostic” and easily paired with both commercial and OER textbooks for Math, Physics, Economics, and Computer Science.
