I am an Appalachian Alumnae. I was Greek at previous school, then transferred. Recruitment is not as competitive as the larger NC schools, like UNC or Duke, but remember that no recruitment process at any school is a cakewalk. Recs are not absolutely required, but they would certainly help you if you have them. This is only the second time that recruitment has been held in the fall for incoming freshman ladies, and they also eliminated deferred rush for the guys too this year. That has really increased the Greek Life buzz, not to mention the two new Chapters that will be recruiting this fall too (AOPi and SAE). I am sure that the number of women going through has increased quite a bit since I graduated.
Good luck during recruitment and enjoy you time at Appalachian! Let's go Mountaineers!!!
