Phi Theta Kappa (PTK) is the oldest and largest honor society, serving students at a two-year college. "The purpose of PTK shall be to recognize and encourage scholarship. To achieve this purpose, "Phi Theta Kappa shall provide opportunities for the leadership development and service, for an intellectual climate for exchange of ideas and ideals, for lively fellowship for scholars, and for stimulation of interest in continuing academic excellence".

Seattle Central College's Alpha Chi Zeta chapter of Phi Theta Kappa is one of more than 1,300 chapters of this International organization and has been established for more than 25 years. The chapter was chartered in 1992 under the direction of then Vice-President of Students Mildred Ollee who became one of PTK's biggest supporters and, eventually, president of Seattle Central College.

The first chapter advisor was Debra Sullivan who helped to establish the group in the Seattle Central College culture. In 1995 former English professor Laurie Cohen became the advisor and the chapter grew both in membership and activities. During the next seven years, Alpha Chi Zeta earned its status as a Five-star Chapter and was awarded International recognition for its endeavors.

In the fall of 2002, Nada Oakley became the chapter advisor and she continues to the present in this role. During the past 15 years, the membership of Alpha Chi Zeta has nearly tripled. The chapter has earned numerous awards, both at the Regional and International levels, for its activities and leadership opportunities. Our chapter has frequently been named as one of the Top-100 chapters internationally.

Today, Alpha Chi Zeta chapter offers its members many opportunities for both personal and academic growth through its weekly meetings, service projects, and leadership training.
