2. China's vocational certification system does not recognize the existence of the profession of "threader", so domestic certification is mainly based on folk certification and commercial certification. In addition, because of the openness of foreign certification, a considerable number of people in China have passed the certification of American threaders and European threaders.
3. Some well-known threading associations abroad.
1)USRSA American Thread Association (www.usrsa.com)
American Threading Association (USRSA) is an international organization and enjoys a high reputation all over the world. Founded in 1986, it has more than 20,000 members all over the world, including racket technicians, professional coaches, equipment retailers, equipment manufacturers and many fans of tennis, badminton, squash and squash. Certified Beater (CS) and Master Beater (MRT) sponsored by the Association are internationally recognized technical qualifications. Threaders are proud to be certified by CS and MRT. Usually, they need to pass this certification to become the designated threaders in international tennis professional competitions at all levels.
CS certificate is used to certify the basic racket maintenance service ability such as threading, changing handle skin and changing handle. MRT certificate is used to certify higher-level professional and technical personnel engaged in racket threading maintenance, and the threader who obtains this certificate must master higher threading technology and have rich product knowledge.
USRSA and the racket factory highly recognize the working ability and experience of those who hold MRT certificates, and encourage players to invite those who hold MRT certificates to serve them. In the sales of rackets, people who hold MRT certificates are also highly respected. Obtaining MRT and CS certificates requires comprehensive examination, including written examination and practical operation. The two exams have both theoretical knowledge and practical operation-threading, changing the handle skin, changing the handle and so on. Simply put, a threader who has obtained MRT certification is a person who can fully grasp the performance and technical parameters of the racket and clearly convey the performance of the racket to the athletes.
2)ERSA European Spinning Association (www.ersa-stringers.com)
In the summer of 200 1 year, the European threader association (ERSA) was formally established. At first, ERSA, as the European branch of the American Cable Dealers Association, provided the most authoritative examination certification and technical support for European cable dealers. In 2003, ERSA was separated from USRSA and became an independent association, but there is still a lot of close cooperation between ERSA and USRSA. ERSA also provides an internationally recognized threader certification exam, which is completely consistent with the certification issued by USRSA (ERSA and USRSA are the only institutions in the world that are qualified to issue this threader certification). At present, ERSA has more than 3,000 members in more than 30 countries and regions, including leading brands in racket industry, tennis players, tennis coaches, sporting goods retail stores, manufacturers, sales organizations and tennis enthusiasts.
