The teacher qualification certificate examination itself does not directly provide preferential policies. However, depending on the specific policies of different regions, holding a teacher qualification certificate may have some indirect benefits. For example, it may be easier to obtain interviews when applying for jobs in educational institutions, or you may enjoy certain employment priorities in some regions. In addition, some local governments may provide housing subsidies, tax exemptions and other preferential policies to teachers who hold teaching qualification certificates. For specific circumstances, please refer to relevant local policies.
