The reason for the loss of rural kindergarten teachers

Their qualifications to enter the kindergarten are low, and there are few fresh blood supplements.

The kindergarten could not provide them with learning opportunities. 3. ** Teacher's personal factors ** - ** Personal influence **: A teacher's age, professional title, and length of service are negatively related to the turnover rate.

It is difficult for kindergarten teachers to form a positive and lasting professional identity. 4. ** Education resource factor **: Although the education resources in rural areas have improved, they are still not as good as those in the county. Many teachers choose to go to the county for the sake of their children's education. 5. ** Financial factors **: The salary in the county is higher, and you can earn extra income by tutoring students during the summer vacation (such as the transition period). 6. ** Social factors **: Working in the county can allow you to come into contact with a wider social circle. Building relationships with parents can bring convenience to your career and life. 7.
