I pledged/initiated Fall 99/Spring 2000, and around that time, my chapter was going through the transition of saying Recruitment instead of Rush, collegian not undergrad, Member Development and not Frat Ed, etc.

They could have easily called the undergrads "actives" prior to this time, but it was never used while I was in school.

The 3 local sororities on campus still use active and inactive, though.
