As a karate instructor, you teach martial arts to children and adults. In this position, you demonstrate various karate techniques to your class, help youth develop the muscles and reflexes needed to succeed at karate, evaluate your students as they progress through belt levels, and otherwise help to embody the ideals of karate. Some karate instructors are active participants on a sporting level and may visit tournaments, engage in mixed martial arts bouts, or have practice matches with teachers and students from other schools. Most karate instructors work with children, so you may need to talk with parents, provide personalized feedback and counseling, and otherwise ensure that students develop both the physical and mental skills they need.
