This paper selects 16 representative colleges and universities libraries in Beijing area as the investigation objective. It investigates the libraries' and the librarians' understanding of the professional qualification certification system and expectations through questionnaire survey, and its feasibility in university libraries and the existing obstacles. The results show that the main obstacles of the current professional qualification certification to colleges and universities libraries are lack of a unified industry management and relevant legal protection, and how to properly handle the relationship between the professional qualification certification system and the current title appraisal system and position evaluation system. Therefore, voluntary application to the qualification certification should be tied to the salary and welfare, and part of the posts should be certified first. Secondly, the authority and certification team are responsible to promote. Furthermore, the professional qualification certification should be voluntary applied in universities or colleges, or selected and gradually popularized by the competent department. It is necessary to straighten out the relationship between position settings of the institution and professional and technical titles system of the library.
