As long as the certificate is formal (the certificate must be stamped by the issuing authority), the technology is real and can be used anywhere. It is still very beneficial to have a formal mechanic certificate. It is easier to enter the factory and the treatment may be better (premise: see the certificate and skill level). It's also good to jump from one job to another if you want.

I have a cousin who studied CNC before (technical school/education for half a year) and worked as an intern after school for 65,438+0 years. Later, I entered a company in Hangzhou. I once participated in the Xiaoshan District Numerical Control Skills Competition, won the third place and issued a grade certificate. Later, many companies hired him, because the boss valued him at that time, paid him well and didn't resign.

Now I have also studied numerical control, and I have a formal mechanic's certificate (the steel seal was issued by the province). I work in a Japanese company, and my position is a mechanic of CNC lathe group, and my treatment is good. When the minister took a fancy to my official certificate and a little CNC lathe skills, he gave me a "counterpart".

Nowadays, 80% or 90% of people who want to find jobs in factories need diplomas (skills). If not, they have to pay someone to fake it. It is not easy to use (the fake certificate has no steel seal), which leads to the manufacturer's distrust of you.

In short, it is good to have a formal diploma. As for the latter question, there is no such statement. Yes, the mechanic's license is your skill "ID card".

Keep it well.
