This paper analyzes the research status of " 1 + X certificate " in China, and finds out the key problems in the implementation process of " 1 + X certificate ". For example, the "1 + X certificate" system lacks top-level design basis, relevant supporting systems are not perfect, there is a lack of unified certification institutions and national level certification standard system, the "three education" foundation of vocational colleges and training evaluation organizations is relatively weak, and the specialty construction and curriculum system construction of pilot colleges need to be improved. In order to do a good job in the pilot work of the system and realize the reform and development of vocational education and training system, this paper takes schools, professional construction and curriculum system as three levels, takes the relevant laws and regulations of vocational education, policies and training evaluation organization vocational ability standards as two pillars, constructs the " 1 + X certificate " implementation model of " three levels + two pillars ", and improves the research on the implementation path of " 1 + X certificate " in higher vocational colleges from different perspectives.
