Each Lambda Sigma chapter plans a unique program of activities designed to achieve the purposes of scholarship, leadership, fellowship, and service.
Since the spirit of service is a strong bond between Lambda Sigma members, many chapter activities are service-oriented. The Lambda Sigma National Board has identified service to underserved and at-risk youth as a focus for the national organization. In order to be eligible for honor chapter consideration, chapters are required to participate in at least one service activity with this focus and are encouraged to make service to underserved and at-risk youth a focus throughout the year.
Chapters may also serve their campuses by assisting with freshman orientation, tutoring, mentoring, guiding campus tours, ushering at special events, sponsoring a college quiz bowl, or cleaning up the campus. Many chapters are also involved in community service through projects such as visiting homes for the elderly or handicapped, raising money for local and national charitable organizations, assisting with voter registration, or organizing blood drives. Chapters may choose to plug into existing service projects on campus and in the community that are sponsored by other organizations or they may plan and organize their own service events.
Other activities include social events as parties, dinners and dances, and chapter fundraisers which might include bowl-a-thons, auctions, dance-a-thons, or sales of buttons, flowers, t-shirts, used textbooks, birthday cakes, and even Christmas trees.
The National Presidents’ Leadership Conference is held annually to bring Lambda Sigma presidents together to share ideas among chapters. Each chapter also conducts activities to inform, select, and initiate new members in accordance with the rituals of national Lambda Sigma.
