The national square dance coach qualification examination is divided into three levels, two levels, one level, advanced level and tutor level. From low to high, the third level is the lowest level, and from here on, the tutor level is the highest level. You can't skip grades at will, and you must strictly implement the grading requirements. If you don't have a certificate before, you must apply from the third level. If you have obtained the qualification certificate before, you can apply for a higher level (but you can't leapfrog). The only way to get the certificate is to participate in the training course for square dance coaches jointly organized by the Gymnastics Management Center of the State Sports General Administration and the National Line Dance Promotion Center. After passing the exam, you can get the qualification certificate of the corresponding level.
