China's coaching certificate is divided into ABC three levels. In the past two years, I have just added a professional coaching certificate, which is the employment certificate for coaching Super League. C-level certificates are organized by local football associations themselves. Invite domestic lecturers to teach, and if foreign lecturers are on tour in China, they can sometimes borrow them. For example, Kramer 200 1 of Germany organized a class C in Yunnan Football Association. The time is usually two weeks. C-level coaches generally serve as amateur teams after graduation. Coach from the youth team. The content of study is the basic knowledge of football tactics, training organization, introduction to sports medicine, etc. Class B lasts for about three weeks. Class B must have a Class C certificate. Class A is generally sponsored by China Football Association. Students are recommended by local football associations and clubs, and must have a Class B certificate. The general time is 4 or 5 weeks. In addition to the basic knowledge, we should learn all kinds of complicated techniques and tactics, formation, team building, psychology and sports medicine in detail.
