Rules for membership are set by the International English Honor Society Sigma Tau
Candidates for undergraduate membership must have completed a minimum of two college courses in English language or literature beyond the usual requirements in freshman English. The candidate must have a minimum of a B or equivalent average in English and in general scholarship, must rank* at least in the highest thirty-five percent of his/her class, and must have completed at least three semesters or five quarters of college course work.
Candidates for graduate membership who did not hold undergraduate membership must be enrolled in a graduate program in English or one of its specializations, have completed six semester hours of graduate work or the equivalent, and have a minimum grade point average of 3.3 on a 4.0 scale.
The membership fee is $40, one-time, for a lifetime membership. In addition to chapter opportunities, members receive a personalized Sigma Tau Delta membership certificate and official Society pin, and are eligible to apply for Sigma Tau Delta scholarships, participate in international conventions, and submit original work for publication and writing awards.
The English department at CCSU invites eligible students to participate every fall semester and new members are celebrated at an induction ceremony.
