Ruby on Rails

Hello:

I have an interesting yet somewhat strange task. Currently, there is a form in my app which adds just single record for certifying tutors. The group wants a way for volume purchasing where a coordinator can login and add multiple tutors in one form. I was considering a nested form or form object but since the certificate actually follows the individual instead of coordinator, I am now thinking it is best if multiple records under the "Certifcation" model get created under a single form. I really don't see why I'd need an entirely separate model for this. Would I need to implement a "hacky" solution for this?

Any advice would be greatly appreciated.
