I think it all depends on the chapter and certain other tangibles. I didn't receive my diamond sister until my senior year (three semesters after I was initiated) because I studied overseas one semester, and our chapter had so many women ahead of me in line to take a diamond sister (we go based on seniority). Technically, I also should not have received a diamond sister the semester I did, because (from what I was told at that time), the Membership Education VP (and NMC, from my understanding) is not supposed to take a diamond sister during her term of office. Since I only had that year left as a Delta member, however, I was able to take a diamond sister.
