Sigma Kappa NMs also wear the letters on their NM pin so it makes sense to me that there's no prohibition on wearing letters before initiation.

Realistically, many times when you join an organization you get something that labels you a member, a T-shirt, a membership card, etc. How many new members know what it really means to be a member of their new organization? How much work will be involved? What it stands for? Not knowing secrets of a sorority don't mean you don't want to yourself up to the highest standards in its name. Wearing the pin or the letters serves as a reminder of that.

I agree with a previous comment that a pledge class just doesn't go along with tradition unknowingly. Actives pass that along.
