How to become a karate teacher
Find a master teacher.
Depending on where you live, there may be many karate teachers or very few near you. In rural areas, it may be difficult to find someone proficient enough in this martial art to sufficiently guide you.
If you live in a highly populated area, you may have to pick a good teacher from among many. The most important part of this process is to find a teacher that works well to motivate your development and who is capable of teaching you advanced skills.
