Adult education is a training where participants have a job and gain a qualification while working.

Within the framework of adult education, the CNC machine operator training of 4S-2000 Ltd. and the György Inczédy Vocational High School of the Nyíregyháza Vocational Training Center was started. In addition to the company's employees, workers of other companies also applied for participation in the group. The condition for participation was the pre-qualification in cutting. The training was attended by traditional machine operators as well as CNC operators who either have no official qualifications or can work only on one of the CNC turning or CNC milling machines. The one-year education consists of a theoretical and a practical part and closes in an examination and a relevant certificate. The education is provided by the György Inczédy Vocational High School, the site and the material conditions are provided by 4S-2000 Ltd.
