Eligible and interested students can attend one of two informational meetings held in early February. At these meetings, current members explain the organization and its goals. Applications can be obtained only at these meetings. From the complete applications, about 100 candidates are selected for the interview. Fifty initiates are identified by this process.
Selection takes place in the spring semester of the freshman year.
Active membership occurs in the sophomore year and life-time inactive membership thereafter. There is a strong emphasis on leadership potential and academic credentials. Lambda Sigma is active on campus, conducting Faculty-Student luncheons, informational poster routes, new student tours, and a variety of service projects. 3.3 Tau Kappa is an ever-changing group. Each year fifty new juniors come together to set goals and organize activities for the following year.
