NPHC Members - ?????

[Senusret I]

While I don't speak for any chapter of any NPHC organization but my own (which does not currently have neophyte presentations) I would say that in my observation, the presentation of neophytes to the public is an important tradition among undergraduates. I wouldn't say that they HAVE to wait to wear paraphernalia (because that would probably be considered hazing) but the specialness of the event, along with the tradition of the campus probably suggests that the initiates wait for an official introduction to their campus.

And of course, not every undergraduate chapter has neophyte presentations.

ETA: The neophyte presentation is such a special event at many schools that they "regulate" such events. For example, a few schools mandate that all such presentations be held on the same day (or not at all)....other schools require that you request the space (even outdoor spaces) in advance. So, the schools indeed know that there is a gap between initiation and "debut" and are supportive of the discreet period in between.

Again, just my observation.
