* Your school's policy: Each school and school district has its own attendance policy. Some are stricter than others. They may have specific numbers of absences allowed before consequences occur, or they may use a more flexible system that considers excused vs. unexcused absences.
* Your age/grade level: Policies might differ for elementary, middle, and high school students.
* The reason for the absences: Excused absences (due to illness, family emergencies, etc.) are generally treated differently than unexcused absences (truancy).
* State laws: Some states have laws regarding compulsory attendance and the number of allowable absences.
To know how many school days *you* can miss, check your school's student handbook or contact the school administration directly.
