How do you get appointed or accepted into the US Naval Academy?

Answer

As an old alumni of USNA I can tell you that you must first request information and application from the Naval Academy. Once this has been received by them you have to contact a nominating source (your Congressman/woman, your Senators or be the son/daughter of a career military person, or be on active duty in the military to get a Secretary of the Navy nomination).

These are but a few of the nominating sources. You will then have to interview with one or all of them to get the highest nomination you can (the process is extremely competitive, apply early). The most important item in the process is do you really want to enroll there and do you want to give 5 years of your life to the military? If you can tolerate most basic rights being taken away for the first year and live under stringent military education/training for the remaining 3 years then you just may have what it takes. Do you really want it? Getting past the Plebe year is one of the most exhilarating experiences because so few actually make it.

Basically, here's what you need:

Solid GPA: 3.9-4.0 w/o AP or >3.5 w/ AP -It is to your benefit to take AP Courses
Good Test Scores: You need to have at least a 600 in each area of the SAT. That is a good minimum. (I got a 1950 overall and was accepted.)
Physically Fit: You take a CFA and you must pass in order to be accepted.
Sports: It will be to your benefit to play a sport... almost everyone that gets accepted does...
Leadership: Student Government, Sea Cadets, JROTC - Something that shows that you can handle responsibility.
Nomination: You must apply for this early to be a prime candidate. Comes from your Senator, Congressman, President... ect.
Recommendations: Yes, your math and English teachers need to like you. They have to give you an endorsement.

Overall, they look at the whole person, so each of these aspects are important... equally important.
