One of the ways our instructors are interviewed is to do an evaluation of a student, his strengths as well as his weakness, and provide a course of action to improve. Most legitimate instructors will do this eval free of charge. The second way to gain insight as to an instructors communication skills is to watch him give a lesson. Hitting as well as most skills are not "one size fits all", that said there are however several fundamental that do have to be achieved,don't be afraid to ask questions.The use of video in achieving a mental picture as well as a physical muscle memory, are also essential. Finally listen to your son or daughter, kids have an inate ability to read people, they Do know those who are truly trying to help vs. those who are just out to make a buck.......hope this helps....Larry Williams
