Research Results

Past NPC research efforts have included national initiatives in partnership with Gallup and Purdue University, along with the Center for Fraternity and Sorority Research. 

Gallup-Purdue Index: Fraternities and Sororities Understanding Life Outcomes 

The Gallup-Purdue Index yielded important insights for colleges, educators, employers and students on the factors that contribute to the collegiate experiences of members. It helped uncover which college experiences are related to key student and graduate outcomes. 

Key Finding: 

Respondents who identified themselves as members of fraternities and sororities – both collegiate and alumnae members – were more likely to report receiving emotional support as an undergraduate, participating in experiential learning and possessing a stronger sense of overall well-being, workplace engagement and alumni attachment to their alma mater. 


Sorority Membership and Educational Outcomes: Results from a National Study 

NPC research regarding sorority membership and educational outcomes also found correlation between sorority membership and retention, graduation and “on-time” graduation rates. 

  • The first-to-second year retention rate for collegiate members of sororities (93%) is higher than for nonmembers. 
  • The six-year graduation rate for sorority members (84%) is also higher than the equivalent rate for nonmembers. 
  • The four-year “on-time” graduation rate for sorority members (58%) also surpasses the four-year rate for nonmembers.
