About PTS

Pi Tau Sigma is an International Mechanical Engineering Honor Society.

Pi Tau Sigma's core values are:

  • Integrity (soundness of character and moral conduct),

  • Service (serving the mechanical engineering profession and the community), and

  • Leadership (being foremost and fostering initiative through example in a professional manner).

The objective of this organization shall be to encourage and recognize superior scholarship, to foster the high ideals of the engineering profession, to stimulate interest in coordinate departmental activities, to promote the mutual professional welfare of its members, and to develop, in mechanical engineering students, the attributes necessary for effective leadership and civic responsibilities.

Mission Statement

To promote superior scholarship by providing a free and convenient tutoring, prepare undergraduate engineers of the advances in the industries through informative speakers and facility tours and encourage fellowship among engineers through club activities.
