Yeah see I had those same questions. Apparently...per my recruiter, you can't be a "current" HPSP student (meaning you can't be in the scholarship at the time of the HPLRP). But as soon as you get out of school and are assigned your station, you are then eligible because you are no longer an HPSP participant, instead you are a commissioned active duty officer. As far as the graduate program. He said he had to call some general to find out but all the other navy personnel in the room at the time of me asking seemed to think that an MPH is qualified since it is a "health field" in the navy. So as far as I'm understanding from what the navy is telling me, I would qualify for the HPLRP after I get out of dental school...it would just tack on more years of service. I've e-mailed a couple of people in the Navy that I can trust for accurate answers...I'll let you know what they tell me. I'm not sure about the recruiters man...they really do try to tell you only what you want to hear...it's always better to ask around.
