Sigma Gamma Tau is the National Aerospace Engineering Honor Society. The purpose of Sigma Gamma Tau, as stated in the preamble of the Society's national constitution, are: "to recognize and honor those individuals in the field of Aeronautics and Astronautics who have, through scholarship, integrity, and outstanding achievement, been a credit to their profession. The society seeks to foster a high standard of ethics and professional practice and create a spirit of loyalty and fellowship, particularly among students of Aerospace Engineering." 

At Texas A&M University the organization is focused on giving back to those who are pursuing a degree in Aerospace Engineering. This is done through hosting test reviews, facilitating a mentorship program, and having different events to foster a community within the department.
