Sigma Tau Delta's central purpose is to confer distinction for high achievement in English language, literature, and writing, and the organization is dedicated to fostering literacy and all aspects of the discipline of English. The Society offers its members tens of thousands of dollars in scholarships, internships, grants, and awards, as well as publication opportunities in its journals "The Rectangle" and "The Sigma Tau Delta Review." Annually the Society provides an international convention, where over 1,000 students and faculty participate in scholarly and creative paper presentations, workshops, and roundtables, and hear featured speakers such as Ursula K. Le Guin, Neil Gaiman, and Poets Laureate Kay Ryan and Natasha Trethewey.
