By the time they reach high school, many teenagers have already devoted hundreds or thousands of hours to pursuing their passions, developing significant expertise. As a result, they are in a great position to teach beginners or even those children who have developed some early skills. In the case of academic subjects, high school students with strong demonstrated classroom performance are very capable of assisting elementary and middle school children with a variety of subjects. Children often enjoy learning more from a teenage “buddy” who they can relate to than an older professional.
