Can a teacher exclude a child from school because their behavior arises from the loss of essential accommodations, leaving them without any alternatives or support?

I am wanting to support the family to navigate this so I am wondering if this letter I drafted would help the situation.

I am writing to formally request a SEND Assist referral for my son, [Child’s Full Name], who is currently enrolled in the special education program at ____ Primary School. Due to his neurodivergent profile, [Child’s Name] relies on a specific object ______ for emotional regulation and predictability. While I understand the school has raised safety concerns, I believe these can be addressed through reasonable adjustments and trauma-informed planning. This has worked in the past, where we have been given the opportunity to come together to work on a solution that works for everyone.
Despite previous meetings and discussions about his behaviour, no resolution has been reached, and recently [Child’s Name] has been excluded from school and left in the care of a family member because I could not meet with the teacher that day due to work commitments, but I was available the following day. This is now impacting his right to inclusive education under the Disability Standards for Education 2005.

I am requesting SEND Assist involvement to:
- Assess the regulatory role of the object and propose safe alternatives
- Support the school in implementing inclusive, neurodivergent-friendly strategies
- Ensure [Child’s Name] can return to school safely and respectfully

Please confirm that this referral will be initiated. If not, I will escalate the matter to the Department of Education and seek support through Disability Services and allied health professionals.

Thank you for your time and consideration.
