Generally speaking, the Education Bureau will examine and approve the application for suspension from school according to the school's policies and relevant laws and regulations. They may consider the students' academic situation, personal reasons, family factors and other factors to make a decision. If the application for suspension from school does not conform to the school policy or the regulations of the Education Bureau, it may be rejected. Usually, the reasons why schools refuse to apply for suspension include psychological barriers caused by heavy academic pressure, bad relationship with classmates, bullying, family problems and so on.
