For GRadplus, it really just has to be a graduate program at an accredited school, and can't exceed your COA. Other than that, it's really your choice. There are pros and cons to it, depending on what private loans are available to you. I got a private loan through my state that had a crazy low index rate for the interest, so I took. However, this next year, the bond they had to use for new loans was so pricey, that index has gone away. I'll probably just use the GradPlus next year. One tip, through the government directly, the interest rate is only 7.9%, but the origination fee is 4%. Overall, I think the lower interest is better.
