College coaches swarm to the championship events to watch high school athletes compete. Even a coach who isn't in attendance requests the rosters from these competitions. They then send recruiting letters to athletes who might be potential contributors to their programs. Many athletes will receive a letter after attending a national championship or regional competition. This mass mailing most likely will include a sport questionnaire.
Questionnaires are key to the recruiting process.
The returned questionnaire tells the coach you want to be recruited. A questionnaire left sitting on your desk may ding you from a school's recruiting list. Regardless of what you already have sent to the coach, fill in the questionnaire and send it back. If you don't hear back from a school, call or send another letter to the coach. Many college coaches will want to see a video of you in action.
