At present, China is in a critical period of digital transformation of education, and in order to fit the important idea of “strong teaching first, strong teachers”, the development of teacher competency analysis has become a key anchor point to meet the demands of this reality. The article takes some young teachers in higher vocational education as the research object, constructs a competency model of young teachers in higher vocational education based on PLS-SEM based on the four dimensions of achievement motivation, personality traits, cognitive ability and cultivating students, and puts forward the research hypotheses. Finally, the relationship between different competency elements and the cultivation of senior young teachers is explained empirically. The results show that achievement motivation, personality traits, cognitive ability, and training students have a significant positive effect on the training of senior young teachers, meanwhile, competency has an important mediating effect in the training of senior young teachers.
