The professional course of Wuxi Electric Welding Training School has changed from "knowledge-oriented" to "integration of learning and doing". At present, the aim is to integrate vocational education diplomas and certificates to improve students' vocational ability and employment competitiveness. In order to further broaden the knowledge of students in training schools, vocational education and training courses are divided into professional core courses and professional orientation courses.

It not only increases students' broad professional foundation, but also carries out job-oriented professional skills training, taking into account the actual needs of students' career development.
