Unexcused absences are instances when a student is absent from school without a valid reason or permission from a parent or guardian. These absences are not approved by the school and are typically considered to be a violation of school attendance policies.

It is important for students to communicate with their school and provide valid reasons for any absences to avoid being marked as unexcused. **

It is important to prioritize attendance and communicate any issues or concerns that may be causing frequent absences. **

Excused absences are not inherently bad, as they are typically granted for valid reasons such as illness, family emergencies, or religious observances. However, excessive excused absences can still have negative consequences, such as falling behind in school or work, missing important information or opportunities, and impacting one's overall performance. It's important to communicate with teachers, employers, or supervisors about excused absences and make efforts to catch up on missed work to minimize any negative impact. **

Unexcused absences, on the other hand, may result in a deduction of points or a lower grade, depending on the specific policy in place.
