The current ESSA Act is constantly improving in maintaining educational equity. Still, the introduction of the Act and the implementation of policies rarely reflect how to achieve educational equity by supporting and promoting teachers work enthusiasm and improving educational equity to promote students overall progress in the long-term educational goals. This paper mainly takes Herzbergs two-factor theory of health factors and motivation factors as the theoretical research basis. It analyzes that the rational application of dual theory can improve teachers work enthusiasm and promote the development of educational equity. Studying teachers job-related motivating factors can generate job satisfaction, thereby promoting and enhancing teachers job satisfaction. As a relevant administrative and legislative research institution, it can investigate the content of teachers work to find out whether teachers have a sense of accomplishment in their work, whether they recognize teachers work, and whether there are problems in the work process plan. At the same time, in teacher-based assessment policies, we could see that objective measures of student growth, observational measures, and the use of assessment systems to drive targeted support are all associated with motivational factors that motivate teachers. Research on the health factors of relevant teachers requires policy and administrators to ensure the essential work and environment of teachers, as well as living conditions and wages.
