Undergraduate teacher vocational skills training is a systematic project that requires research and exploration from the combination of theory and practice. From the current situation of the construction of the teaching staff in Chinese universities, the traditional training model for university teachers in the past has played a good role in ensuring and promoting the improvement of teachers' teaching level, but it has gradually highlighted the significant limitations of the model itself. In this regard, this article conducts research on issues related to lifelong vocational skills training for vocational undergraduate teachers. This article also analyzes the current training mode analysis and existing problems. Due to the traditional emphasis on theoretical teaching and the neglect of educational practice, it seriously affects the cultivation of vocational skills for vocational university students. How to improve the vocational skills of vocational university students has become a major issue that major local undergraduate colleges in China need to explore. At a certain time period throughout the entire learning process, it is necessary to equip fulltime and part-time guidance teachers, formulate assessment standards, and strictly implement them. We should clearly incorporate teacher vocational skill training as a task and indicator into the education and teaching system and student activities, and establish standardized and reasonable assessment standards.
