Alpha Sigma Lambda National Honor Society is a nonprofit organization devoted to the advancement of scholarship and to the recognition of nontraditional students continuing their higher education. The Society was established in 1945-46 to honor superior scholarship and leadership in adult students. Today, with nearly 250 institutional chapters throughout the United states, Alpha Sigma Lambda is the oldest and largest chapter-based honor society for full- and part-time adult students.

For the nontraditional student, Alpha Sigma Lambda stands as an inspiration for continuing scholastic growth, a builder of pride through recognition, and an invitation to associate with similarly motivated students. The Society represents a prestigious opportunity to recognize the special achievements of adults who accomplish academic excellence, while facing competing interests of family, community and work.

Membership in Alpha Sigma Lambda is by invitation only. In January of each year, the officers of the organization at Columbia College contact eligible students to apply for membership based on the following criteria:

• Thirty graded semester hours of course work earned at Columbia College.
• Ranked in the top 10% of students enrolled in the Evening College, either full-time or part-time. This ranking is based on the cumulative GPA at the end of the fall semester.
• Upon completion of the requirements for membership in ASL, new members are inducted at the Evening College Recognition Ceremony that is held each April.
