HSGTO Attendance Policy

We strive to create an orchestral experience for our students that is musically rewarding and challenging.  In order to achieve this, it is important for all involved to exhibit commitment to rehearsal attendance, integrity in music preparation, and proper rehearsal etiquette.  With this in mind, we would like to provide a clear attendance policy to ensure a success for the orchestra as a whole.

1. Attendance for all rehearsals and concerts is mandatory.

2. Students will be permitted one excused rehearsal absence per concert. All excused absences must be communicated by email to directors@hocoyo.org and approved by the directors at least two weeks in advance of the absence (except for sickness and emergencies). Absences due to illness must be communicated before 3pm on the day of the rehearsal.

3. Excused absences may include the following: college visits, school concerts, athletic games (not practices), school Spring trips.

4. All other absences are unexcused, including: Social activities, school homework/projects, studying for tests, etc.

5. After any absence, students may be required to play for the directors before the next rehearsal at 6:00PM.

6. After one excused absence per concert or after ANY unexcused absence, the student’s participation in HCYO will be subject to review by the directors.

It is our expectation that all students will abide by these guidelines, thus creating a more positive and productive musical experience for everyone.
