I'm not sure why you need this assumption, but I'd say yes if it makes things easier.

Thanks for your reply.

The reason I asked was that I had an Application model class and an Applicant model class. But if an applicant's applications always have the same information, then I only need to have the applicant fill out his information once and just associate him with a job when he applies, doing away with the Application class (I suppose this is what was in mind in the assignment, but I just wanted to make sure). 

Edit: Turns out that doesn't work, for the date might change with each application.

You could make a copy of the previous Application object and change the date. You need to be able to tell the two applicants are the same person though, which may be difficult because there's no registration/login/logout in this assignment. If you want you could use email as an identifier.
