The young fraternity competed in volleyball, basketball, riflery, tennis, track, and Greek Week. Brothers served in dormitory government, the University Council for the United Nations, University Radio, and other organizations. For a public service project, brothers and pledges visited the Odd Fellows Home in Mattoon, washing windows, caring for the grounds, and spending time with residents.
Lambda Sigma Chi placed first in grades among EIU fraternities for consecutive quarters and consistently exceeded the all-men’s average. At the 1971 Greek Games, the fraternity earned a scholarship trophy, and Russ Guimond was recognized for the highest grade point average over the preceding three quarters.
