Why are the thresholds for teacher recruitment getting higher and higher?

In recent years, the threshold for teacher recruitment has become higher and higher. This is mainly because the government hopes to improve the social status and remuneration of the teaching profession and attract more outstanding talents to enter the education industry. At the same time, with the improvement of education level, more and more people are applying for teachers, which has also led to the recruitment threshold becoming higher. In addition, in order to improve the quality and professional level of teachers, the government has also continuously raised the requirements for teacher recruitment, such as increasing the difficulty of teacher qualification examinations and admission standards.
