It can be used as a qualification certificate for workers to engage in corresponding occupations and as the main basis for employers to recruit and recruit employees. The certificate is printed by the National Ministry of Human Resources and Social Security, audited and printed by the Beijing Vocational Skills Appraisal Management Center, and is common throughout the country. It is the only safety qualification certificate recognized by the state, which can be used as a standard to measure the working ability when determining the salary standard of employees. Certificates are owned and kept by individuals, and can be found on the national vocational qualification inquiry website.
