The teachers recruited by the Education Bureau belong to the teachers in preparation, and the Education Bureau is the competent authority of the school. Therefore, the personnel right is in the Education Bureau, and only the teachers recruited by the Education Bureau will have a formal establishment. However, the teachers recruited by the school may be temporary teachers, which are not included in the establishment, or they may be established. The teachers who are openly recruited with the approval of the Education Bureau are also formally established. Teachers' examinations are generally organized by the Education Bureau, but there are also separate career recruitment examinations conducted by schools, and the specific examination contents may be different in different regions.
