Learn as much you can about the leadership institution. Ask a counselor for information and request the institution’s guidebooks and brochures. Use online resources, such as the institution’s website, to augment your search. Speak with someone who was a previous attendee, so that you can get his take on the institution. A well-informed essay will increase your chances of admission.
Define leadership. Expand your definition of leadership beyond having the authority to boss around others. A leader supports and empowers those for whom he is responsible, and he helps others develop confidence in themselves. By expanding your understanding of leadership, you'll be better prepared to write the essay.
Write a strong thesis stating why the institution should accept you. Make your thesis clear and concise. Tell the admissions committee not only how you could benefit from the institution, but how the institution -- and the attendees -- could benefit from your presence.
Highlight your leadership experiences. Whether you were a scout leader or a student body president, demonstrate that you have experience in leadership. Include specific instances when you proved your leadership prowess, such as planning a bake sale or maintaining the school store.
Finish with a strong conclusion. Reinforce your leadership abilities in the final paragraph. Include information about your goals and how being a strong leader is critical to your success. Echoing your thesis, make a winning case for why the institution should accept you.
