I don't know how credentialing works out of my own state, so I can't really help you there; but good luck, Kellie!
In my state, you finish your B.A. before you start your education program. The state offers a special ed credential, but it doesn't include the gifted; they aren't considered special ed here in CA. I earned an additional certificate in gifted ed from UCSD. My certificate doesn't mean much; nothing on the pay scale, and my administrator can choose to send the gifted students my way, or not. It does put my on the district GATE committee, and I do get to do inservice to others on how to serve their gifted students.
