With the development of continuing education, the international community pays more and more attention to its quality evaluation. This study selects continuing education quality evaluation systems of six countries and international organizations, such as the United States and the European Union. By clustering analysis on 34 high frequency keywords with SPSS, which are extracted by the co-word analysis method, we obtain three thematic categories, including planning and management, result-oriented multi-subject feedback， and process-oriented teaching and learning, as well as six core dimensions. Through UCINET social network analysis, it is found that three aspects are reflected in the development trend of international continuing education quality evaluation: strengthening the management and organization construction of continuing education institutions, improving the satisfaction of employers and employees, and meeting the needs of learners. In light of the core dimensions and development trends of international continuing education quality assessment and based on the status quo of continuing education in China, we construct a quality evaluation framework for continuing education. It is suggested that related organizations should actively apply self-assessment, encourage the participation of multiple stakeholders, take into account both process and outcome indicators, and develop learning organizations of continuing education with the capacity for continuous improvement.
