NPC does not advocate using a priority rush system b/c it encourages the ranking of sororities as well as unreasonable expectations among the PNMs about where they'll be invited back. That being said, I went through a priority rush system and my college tried using an invitation system my junior year. It was a nightmare with the tight schedule we adhere to during recruitment. Panhellenic went back to priority rush the next year.
