I'm not sure where you got this info (I've never seen "basic" requirements), and I'm not challenging it, but I do want to make an addendum based on the paperwork I was given by my recruiting office.
Navy Dental Corps: HPSP requirements
cGPA: 3.6 or higher - wrong - you have to have a minimum of 3.0, but to be competative usually you need at least a 3.4
DAT score for TS: 22+ wrong - you need at least an 18. The higher the better, but only the top few percent of people have a 22 or higher. So, it is not even possible to require a 22+
No Moral or ethical issues - depends on your definition of this is
Physically qualified (NO medical waivers) - wrong - I saw waivers on multiple HPSP/HSCP selectees including myself
Meets height/weight standards (body fat used if over HT/WT).
"Letters of Acceptance" for four-year scholarships must be received by Dental Program Manager no later than 1 June of the current recruiting year, final selection dependent upon availability of remaining scholarships. Applications are accepted year round. The recruiters may hold off on submitting the application if no scholarships are currently available. The scholarship money is based around the federal fiscal year that runs from Oct 1st to Sept 30th. So, if scholarships are running low or are all out, the recruiter may hold on to the application and submit it at a time where it coincides with the initial meeting of the selection committe for the new fiscal year. That is what they did for my application.
Just finished NASIS myself, the application process is definitely chock-full of paperwork.
