If you are a High school Junior you can go to the sites and fill out the applications for the Summer Seminars/Summer Leadership experiences..That is actually the first part of the regular application. If you are at all interested you need to do that ASAP because the summer programs have very few openings, and there seems to be some preference given to those that sign up early. Some open Jan 15 some shortly thereafter.
There are several essays, Name a challenge you had in your life and how you overcame it. How do you feel about diversity. Why do you want to attend this Academy and why do you think you will make a good leader, that kind of stuff.
a section to fill out your achievements, clubs, school, community , sports ect, grouped by year 9th grade 10th etc.. They want to know what your leadership position is in each of these areas, always keep in mind they are all about making leaders, not just soldiers.
