Undergraduate students are eligible for active membership if they have completed three semesters or five quarters of the college course, rank in the upper thirty-five percent of their class, and have completed at least two semester courses or three quarter courses in philosophy with an average grade of over the second highest grade of the working scale.
Graduate students are eligible if they meet the requirements established for undergraduates, or if they have completed at least one-third of the residence requirements of the master's degree with a grade average of at least half on the highest grade of the working scale and half in the second highest grade.
In addition to the special requirements for both graduate and undergraduate students above, note that Phi Sigma Tau operates under the umbrella of the Association of College Honor Societies and is a member in good standing of that Association. The Association of College Honor Societies requires that Phi Sigma Tau grant student membership only through a local chapter of our organization and not through the National Office. Consequently, students are eligible for membership in Phi Sigma Tau only if their school has a local chapter and upon the recommendation of the chapter advisor.
