Most golf teachers start out with the dream of becoming a great player on the professional golf tour. However, only the best of the best make it to the tour. Most other golfers who are good enough to turn pro teach the game to the many amateurs who want to learn the finer points of the game.
Play as much as you can once you decide you have professional aspirations. To most golf pros, this idea will come to them during their teenage years. Play for your high school team and try to play in college. Play as much as you can and talk to as many professionals as you can in order to learn the game.
Give it a try. Go for the pro tour. You will always have haunting desires and wonder if you could have made it. If you can't, there's no shame in failing after your best effort. You will be in a better position to become a teaching pro after you have tried to make the tour.
Get certified as a teaching professional. There are several levels of certification that a teaching pro can gain over time. These certifications show your students that you are more than just a fly-by-nighter who has decided to call himself a "teacher." There are certification classes all over the United States, although there are more in places like Florida and California.
Learn the nuances of teaching. This means relating to your students in a one-on-one situation. The certification will help you find employment and gain acceptance. However, the skill of a good teacher comes from the ability to communicate. To do this, know what you are talking about and be patient with your students. The more satisfaction each student gains, the more the word will spread that you are an excellent teacher.
Use videotape to help your students learn what they are doing right or wrong. Videotape their swing and analyze it for them. If you can point out their errors as they watch themselves swing, they will have a better chance of improving and you will have a better chance of becoming a successful teacher.
