This paper first focuses on the problem of quality evaluation of adult education, proposes a data pre-processing method suitable for quality evaluation of adult education - the efficacy coefficient method, and introduces the subjective and objective evaluation factors and the time sequence factors through a variety of weighting methods, and designs the comprehensive evaluation algorithms based on the “pulling the grades method” and the “time sequence weighting method”. Lastly, evaluation algorithms were utilized to analyze teaching satisfaction, student motivation, and internal and external influences on adult education. The results showed that the students’ satisfaction index for all levels of adult education ranged from 0.4 to 0.6, which is between unsatisfactory and average. The main external influences are lack of flexibility in the mechanism, insufficient teaching staff, lack of funding, no advantage, and irrational curricula, which account for 72%, 53%, 48%, 39%, and 24% of the perceptions, respectively. This study is of great significance for the further deepening of the reform and development of adult higher education in China and the healthy development of lifelong learning for all.
