Since colonization, Iota Chi has taken a membership class each semester *. These classes are named in alphabetical order of the Greek alphabet (Alpha, Beta, Gamma, and so on). It has become a tradition for each class to create an alliterative name for themselves (these names can be found in each class' page). 

​

The names and information on the sisters in each class, as well as inducted honorary members, a class picture, and fun facts relating to each class/semester, can be found below:
