According to JMU's sorority recruitment application / registration document:
"ACADEMIC RECORD RELEASE: I understand that to apply for recruitment, I must be a regularly enrolled, full-time student in good standing with James Madison University with a 2.0 or better cumulative GPA. Every chapter's GPA requirements will be listed in the recruitment booklet you will receive at the orientation session. I authorize James Madison University's Student Organization Services Office and Panhellenic Council to verify my academic eligibility."

So it looks like JMU takes "cumulative" into consideration.
Edited to add: What I find a little unnerving is that JMU's Greek Life and/or Panhellenic evidently has "every chapter's GPA requirements," but they aren't giving them out until the orientation session -- is that right? Unless several chapters have a 2.0 requirement, I can just imagine the fun when a few PNMs show up at orientation, only to discover that they have, for all practical purposes, no chance.
Maybe JMU is just following the classic verse by Thomas Gray:
"Yet ah! why should they know their fate?
Since sorrow never comes too late,
And happiness too swiftly flies.
Thought would destroy their paradise.
No more; where ignorance is bliss,
'Tis folly to be wise."
