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. ​​​​

Today is the first day of spring or Motoyi in Blackfoot. It is a time of renewal and new beginnings. After a season of rest, the land comes to life with new growth, movement and sounds. #WeAreCBE https://t.co/HAOFLzXFFf

RT @NickleCBE: Grade 9 morning trip to Fish Creek Park. Students practiced building shelters, making fires, and of course enjoying s'mores together. @nickleschoolparents https://t.co/BCx7FXdm6o

RT @gale_school: Many grade 9 students have been working hard to research and create their Social Justice displays. Today, they presented them to our grade 6 students. #WeAreCBE @Area4CBE https://t.co/yb9tncl83e

RT @cmhsrams: CMHS appreciates our guest teachers. Our culinary students have been providing them with treats every morning. Substitute teachers are essential to our schools. Thank you. #WeAreCBE https://t.co/6VwZdt9i3a
