Primary skills are the lowest among workers' technical titles. The mechanic is a superior mechanic. National technical occupations (jobs) and vocational qualification certificates are divided into five levels: primary skills, intermediate skills, advanced skills, technicians and senior technicians. Elementary, intermediate and advanced skills belong to mechanics.
At present, the recognized senior professional qualifications in China mainly include: the establishment of workers (first-class/senior technicians) who have obtained professional qualification certificates and high-skilled workers as senior technicians.
Such as: senior technician of automobile mechanic, senior technician of maintenance electrician, senior technician of lathe worker, senior technician of locksmith, senior technician of home appliance mechanic, senior technician of laboratory technician, etc.
Extended data:
There are two versions of vocational qualification certificates issued by Ministry of Human Resources and Social Security, namely, vocational qualification certificate (Grade I) and vocational qualification certificate (Grade II/Senior Technician).
With professional and technical (vocational) qualifications or senior technician qualifications recognized by the national human resources and social security departments, employed senior technicians can enjoy the same treatment as deputy senior technicians (senior engineers, senior accountants, associate professors and deputy chief physicians), and senior technicians in many provinces and regions can enjoy senior technician subsidies when they retire.
