​Contact Information Updates

Please notify the school office immediately with any changes of address, telephone numbers (home, business and/or cell), email address or emergency contact numbers. It is critical that we have a current record of contact information on file so we can reach you or other emergency contacts.

Concerns & Complaints

We know that the success of your student is dependent on a strong partnership between families and the CBE. If you have a concern, it can usually be addressed at the classroom level. Your first step is to arrange to speak privately with your child’s teacher. If you feel your issue is still unresolved, please contact your principal. If you and the school are unable to find a resolution, please see our Concerns & Complaints​ page for additional information, including the process to contact your Area Director. ​​​​
