Getting into SLS is not the same as receiving an appointment.
In relation to competitiveness, the perception of a district’s competitiveness, for the most part, means very little, especially districts that people here have deemed ‘more’ competitive. There is only one individual on each slate that will get in based on pure competitiveness of others in that area. For most districts, no matter the caliber of the entire pool, there will be one or two who rise to the occasion. No matter how qualified, can your ego convince you that there is not someone in the school across town just as qualified? Can you decide, with any degree of certainty, that there is not someone whose dad just retired from the Navy, who just moved into the school across town, who spent the last ten years in the Fairfax County school system? Bottom line, only one will win the prize. To say the district is less competitive because fewer apply is ignorant. To say the district is less competitive because you are, without a doubt, the most qualified, is arrogant. And gerrymandering makes for some strange bedfellows. The small rural school competes with the big city magnet school. The only districts where this might matter is the 40 or so that do not normally fill their vacancies. And for USNA, this is a thing of the past.
Only one winner. All the rest are dumped into the national pool, where the only competitiveness is how you and your preparation rank nationally. This is the primary reason why some areas send more candidates to the SAs than others. With that said, however, USNA85 states that, being equal, the candidate from the lesser represented area will receive the appointment. This concept is far removed from the area that I am from, but I have no reason to doubt her. Probably only happens though in a very very few locations.
