As an honor society, Sigma Gamma Tau is primarily a service organization for Aerospace education. The student chapters participate in activities such as tutoring, hosting campus advisors, and serving on academic committees. Sigma Gamma Tau complements the work and goals of AIAA, the corresponding professional society in which most student activity is centered. Sigma Gamma Tau members traditionally are members of AIAA, and the two organizations frequently co-sponsor scientific, professional, and social activities.
