* School policy: Each school has its own attendance policy, often with specific consequences for exceeding a certain number of absences (excused or unexcused). Check your school's handbook. Missing even a few days can impact your academic standing in some schools.
* Reason for absences: Excused absences (doctor's appointments, family emergencies) are generally viewed more favorably than unexcused absences (skipping school).
* Impact on academics: Even a few absences can significantly affect your ability to keep up with coursework, particularly in demanding junior year. Missed classes mean missed assignments, tests, and opportunities for participation.
* Your individual situation: Some students can handle missing a few more days than others, depending on their organizational skills, study habits, and the support they receive from teachers and family.
Generally, aiming for the absolute minimum number of absences is best. Anything above 5-10 absences (total, excused and unexcused) starts to become a concern, especially if they disrupt your academic progress. More than 10-15 is a significant issue in most high schools.
In short: Consult your school's attendance policy and strive to attend every day possible. If you must miss school, communicate with your teachers proactively and arrange to make up any missed work.
