What grade are you in? If you are going to be a senior, and you're already doing sports, then being a recruited athlete may be difficult. Trying to be a recruited athlete isn't something you really have a decision in. You can go online and inform the coaches that you're interested, buut usually getting the athletic departments attention and having them recruit you, is usually because the coach in charge of your area has been scanning online your state and local newspapers and such for names that keep popping up. Such as the player who seems to get named every week because they were a major contributor in a game or event. I.e. every Saturday the name john smith seems to pop up with significant football stats. Also. Most of the coaches who take care of your area contact the high school coaches and ask if they have any star athletes that might be interested in the academies. Coaches at the high school level know what the college level is looking for.
So, if you're the athlete that possibly is going to get recruited by other colleges, you're probably of interest to the academy. Remember, 80-85% of all cadets coming to the academy have varsity letters and play sports. Are you the athlete that is probably going to be offered a scholarship from a college for sports? If so, being a recruited athlete is definitely a possibility. But if you probably won't be offered a scholarship for sports from any other university, you probably won't be a recruited athlete by the academy.
Of course, there are some sports that the academies don't get a lot of athletes wanting to participate in. So in many of these sports, the academy will let you be on or try out for the team, but may or may not recruit you. Depending if you're one of the best. Things like being named all state, all conference, winning state chpionship, etc. Matter. Remember too, this isn't intramural sports. Football plays against teams like Notre same and Oklahoma. So, it depends on your sport and grade.
If you are a junior, definitely look into trying to get recruited. If you are going to be a senior, and you already are involved heavily in sports, take the advanced classes.
