University level -
Regarding academics, I think that it would depend on the school. Some schools look at all campus organizations and divide them into categories. (OK, big DUH there.
) An NPC group, as a lone GLO - NPC/NIC/NPHC or other, may get lumped into the service organization category with Angel Flight, Alpha Phi Omega or Circle K and make the awards from there.
National organization level -
Many groups have criteria set up for campuses with 1 to 5 NPC groups, 5 - 10 groups or 10 or more
Even though a chapter may be the sole campus sorority, the national organization sets requirements that they have meet.
Sorry, I am getting long winded.
