There is an article on the DPU quota system for the IFC:
Aaron Weaver, vice president for recruitment for IFC, said the quota policy placed more attention on the quality of the new members.
"In the past, chapters had the ability to set quota at whatever number they wanted to," Weaver said. "We wanted to increase quality instead of quantity."
While only 171 men participated in rush, they represented 71 percent of the 230 eligible freshmen men, which Weaver said was equivalent to previous years. The number of eligible freshmen men affected the number at which IFC set its quota: the goal was 25 new members for each house. Only Phi Kappa Psi reached quota.
