My daughter has been excluded from her ONLY ever primary school graduation due to a suspension. The school will not even consider her attending the ceremony only and then we her parents take her home. 
My daughter has an official diagnosis of ADHD and ODD and now believes she has been punished not once but twice. 
The staff members involved in the incident that lead my daughter to be suspended are also brother and sister which I believe to be a huge conflict of interest they have acted unprofessionally and have made comments such as your mother needs to take you all out of this school. 
I believe the school and education QLD should be supporting her right to attend the ceremony for social developmental reasons and overall mental health and well being as this is a monumental moment in her life that she will never get again! 

My 11 year old child has been treated unfairly to have her right to graduate primary  school removed.
