The elderly care service quality evaluation system is an important prerequisite for the high-quality development of elderly care service in the new era. Over the years, China’s elderly care service quality evaluation system has experienced three stages, including germination, construction, and development with different characteristics. The connotation of the elderly care service quality evaluation suitable for China’s national conditions is to participate in the whole process of elderly care service or product standards, management and evaluation at home and community-based elderly care service, elderly care institutions, medical care, and other levels through multiple evaluation subjects. In the face of the prominent problems of the current elderly care service quality assessment, such as the lag of standardization theory research, the vague connection between local and national norms, and the different cognition of relevant government departments, the next step of the elderly care service quality assessment system needs to work on the standardization and normalization of elderly care institutions, the exploration of residential community elderly care service assessment system, the construction of local elderly care service assessment centers, and the organic connection between local and national elderly care norms, so as to promote the high-quality development of elderly care service in the new era.
