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. Chapters may serve their campuses by assisting with freshman orientation, tutoring, serving as big brother/sisters, guided 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.
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.
