STUDENT ABSENCE: If a student can't attend the lesson it has to be canceled 24 hours in advance (or as soon as possible) via e-mail or SMS directly to the teacher. See our contact page for contact details. For long-term planned absences, the student has to apply for leave in writing to the administration. PERIODE OF BINDING AND TERMINATION: Termination of an ILP contract has to be in writing and sent to the administration 2 weeks in advance. Aurora Vocalis reserves the right to terminate any lesson and contract for lack of payment, if the student is not showing enough progression, or if regular practice is not in evidence. One two week's notice will be given in such cases. REFUNDS: There is no refund due to student absence (regardless of cause). If the lessons are canceled by the teacher, they will be rescheduled or refunded on the next invoice. TEACHING MATERIALS: Books, sheet music, and other teaching materials needed vary and are not included in the fees. Students are themselves responsible for acquiring the required materials. Aurora Vocalis has a limited stock of books available for sale if needed.
