Pros
Occasionally help students and make a difference. You also learn how broken American education is and how philanthropy, particularly from the well meaning, but unaffected further exacerbates the flaws. If your a highly motivated students, I would recommend working directly with a highschool rather than through this top-down organization that makes use of its power and influence to make high-school student voices the least valued, in my view at-least.
Cons
In my view, a structurally flawed vision that views high achieving students as commodities. This starts at the top, with people in their gilded offices making decision far away from student experiences. Student not meeting standards? Kick them out! Often times this decisions are made to protect the "Schuler Brand", something coaches will be taught is the most valuable asset. Your better off working for a grassroots organization that commits to its population then one that arbitrarily chooses winners and losers.
