kdgang,
It sounds like you are looking to write a new member pinning ritual, a ritual to officially recognize the new members as a part of your chapter but not as full members. If you want something to get an idea, my fraternity, Delta Upsilon is non-secret. Because of our non-secrecy, our ritual is online for you to read. I hope that it can provide you with some inspiration.
Here is a link to the associate member pinning ceremony:

One idea would be to design new member pins if you don't have one. They could be a simplified version of your member badge with the secret parts taken off. Or they could be a specific symbol which represents new members for your organization.
Good luck and please let us know how it turns out.
