Access to a Yale education is not limited to Yale students. In recent years, Yale has expanded its offering, including the online Coursera classes which are estimated to have over one-and-a-half million students in 2023. Yale Online — the main hub for Yale’s online offerings — is a catalog that brings together a collection of courses offered to degree and non-degree seekers around the world. The website includes open courses taught at Yale ranging from “Environment Politics and Law” to “The Science of Well-Being for Teens.” It includes non-degree programs with a certificate of completion as well as degree programs offered by professional schools across the University.
