This article based on the current situation of applied undergraduate colleges and universities in the field of mechanical and electrical professional talent training, combined with the evaluation requirements of advanced vocational skill level certificate in the three-dimensional model design of mechanical products, the course teaching content of mechanical and electrical professional talent training is efficiently combined with the standards of vocational skill level certificates, and the teaching evaluation method is integrated with the evaluation standards of vocational skill level certificates. A new model of mechanical and electrical talent training based on the “1+X” certificate system has been constructed, and a new idea of teaching reform of “1+X” vocational skill level system in mechanical and electrical specialty courses has been developed.
