Soccer scholarships at American universities and colleges are every bit as competitive, if not more so, than football or basketball scholarships are. There are over 1,200 men's college soccer programs and over 1,400 women's programs in the country. Getting a scholarship will require that you have years of playing club soccer, attending soccer camps, participating in showcases, and playing for your high school. Then, you have to choose a school in the right division. If you dream of division 1 soccer but your skills are division 2, your chances of getting a scholarship at a division 1 school are slim.
At a division 1 school, the coach has a maximum of 14 scholarships per team. If the school is division 2, there are only 9 scholarships per team. If your school is part of NAIA, there are 12 scholarships per team and NJCAA teams has 18 scholarships per team. Since coaches want to help as many players as possible, chances are even slimmer of getting a full ride scholarship as they try to divide the money up in order to get more good players.
Even though you play for your high school, you also need to be playing on a traveling club team. Coaches take club soccer much more seriously than they do high school soccer. Make sure you play for the best club you can and that you get plenty of game time. If you're on the best team, but the coach never puts you in, your chances of getting scholarship go down. Better to play on smaller name team and get on the field as often as you can.
Also be aware that you'll get more money based on how much you contribute to the team once you are on it. So if you contribute a lot, you can look forward to having your scholarship increase over your college years.
