Since 1970, College of DuPage has been a member of the Phi Theta Kappa Honor Society (PTK). The mission of Phi Theta Kappa is to recognize academic achievement of college students and to provide opportunities for them to grow as scholars and leaders. Currently enrolled students who have earned at least 12 cumulative credit hours at COD and have a cumulative GPA of 3.5 or better are eligible to join. Membership benefits continue even after the student leaves COD.

As part of the PTK experience, students have opportunities to develop their leadership and research skills through fellowship events and two major projects per year: The College Project and Honors in Action (HIA). The College Project is designed to strengthen a supportive working relationship between our chapter of PTK and with the college administration. The project can be anything that benefits the college and is approved by the college administration. Honors in Action combines academic research, problem solving, and action-oriented service to address real-world challenges in our communities. Students follow a plan of research, reflection and action as guided by selected themes chosen by PTK for all chapters.
