Matters needing attention in writing students' leave notes:

1. Students must obtain the parents' consent before filling out the student leave slip, and then they can take leave with this leave slip.

2. Students' leave is limited to sick leave and personal leave. Sick leave: Students can't attend classes due to injuries and other reasons. And they must rely on the diagnosis certificate issued by the doctor; Personal leave: in case of special circumstances during school study, it must be approved according to regulations.

3. Students who cannot attend classes for some reason must ask for leave in advance for approval. Leave within one day, approved by the class teacher; Leave for 2-3 days shall be signed by the class teacher and submitted to the grade for approval. Those who are absent from work without approval are regarded as absenteeism, and those who are serious will be given disciplinary sanctions.

4. After returning to school, you should cancel your leave to the class teacher in time. Otherwise, it will be treated as leave.
