School Adjustments for Sensory Processing and Intellectual Disability in South Australia

The most common thing SA families tell advocates is that their school "knows about" their child's diagnosis but doesn't actually change anything in the classroom. The diagnosis is on file. The One Plan exists. But your child is still melting down at lunch, still being excluded from group activities, still falling behind on tasks every other student completes without a second thought.

Knowing a diagnosis exists and actually adjusting the environment are two completely different things. This post covers the specific, concrete adjustments that SA schools are legally required to consider for students with sensory processing difficulties and intellectual disabilities — and how to demand them using the right legislative language.

Sensory Processing Difficulties: What Schools Must Do

Sensory processing difficulties most commonly present in students with Autism Spectrum Disorder (ASD), ADHD, and developmental coordination disorder. Students with sensory sensitivities can be overwhelmed by fluorescent lighting, classroom noise, unexpected physical contact, food smells in the canteen, or fabric textures in school uniforms. The response — withdrawal, meltdown, refusal, or elopement — is frequently misread as behaviour, not disability.

The Disability Standards for Education 2005 (Cth) (DSE) requires schools to make reasonable adjustments that allow the student to participate in education on the same basis as peers. For sensory processing difficulties, this means the environment itself must be adjusted — not just the student's response to it.

Reasonable adjustments in this area include:

Environmental modifications

• A designated quiet withdrawal space or sensory room the student can access proactively (not as a consequence for poor behaviour)
• Flexibility in seating location to reduce acoustic and visual distractions
• Permission to use noise-cancelling headphones or ear defenders during whole-class instruction
• Modified uniform arrangements documented in the One Plan where standard clothing causes sensory distress

Timetable and routine adjustments

• Advance notice of changes to routine — visual schedules, daily timetable previews
• Modified participation in noisy or high-stimulus activities (assemblies, PE, excursions) with a graduated re-engagement plan rather than wholesale exclusion
• Staggered entry or exit to avoid corridor congestion

Assessment and curriculum adjustments

• Reduced group work requirements where sensory proximity or social unpredictability is a barrier
• Alternative assessment formats that do not require sustained performance in high-sensory environments

Under SA's Positive Behaviour for Learning (PBL) framework, the Department for Education explicitly recognises behaviour as a form of communication. This means that if your child's sensory environment is triggering dysregulation and the school is responding with punitive discipline — rather than proactive environmental adjustments — the school is operating in direct conflict with its own policy framework.

If the school claims no sensory supports are necessary, ask them to show you the documented Functional Behaviour Assessment (FBA) that identified the antecedents to your child's dysregulation. If no FBA has been conducted, that is the first thing to demand in writing.

Intellectual Disability: What SA Schools Are Required to Provide

The 2024 NCCD data showed that students with cognitive disability represent 53.9% of all students receiving educational adjustments nationally — the single largest group. In South Australia, this is the disability category most likely to trigger placement pressure toward special schools. It is also the category where the "babysitting effect" — where students are kept physically safe but not exposed to meaningful curriculum — is most common.

The 2026 amendments to the Education and Children's Services Act 2019 (SA) confirmed that a school cannot refuse mainstream enrolment based on intellectual disability, nor can the Department direct a student into a segregated setting solely because of their disability. The default remains mainstream inclusion with appropriate adjustments.

For students with intellectual disability in SA mainstream schools, reasonable adjustments include:

Curriculum differentiation

• Individualised learning goals aligned with the ABLES SA curriculum framework (the SA-specific tool for assessing students working below curriculum level)
• Modified assessment tasks that demonstrate the same learning in a format accessible to the student
• Chunked instruction broken into smaller steps with built-in repetition

SSO and staffing adjustments

• Targeted School Support Officer (SSO) assistance for specific tasks — not just supervision
• SSO goals documented in the One Plan with measurable outcomes (not "will support student" but "will deliver daily 15-minute phonics activity using Jolly Phonics, targeting [specific outcomes] by the end of Term 2")

Communication and social participation

• Alternative communication supports where verbal expression is limited
• Structured peer interaction programs within the One Plan, not left to ad hoc arrangements
• Physical accessibility, including for extracurricular activities and excursions

A common problem in SA schools is that One Plans for students with intellectual disability include goals about life skills and compliance rather than academic learning. This reflects a low expectation that the student can access meaningful curriculum. Under the DSE, the measure of a reasonable adjustment is whether it enables the student to participate on the same basis as peers — including academically, not only behaviourally.

How to Put This in Writing

Generic advocacy doesn't work well with SA schools. The more specific and legally grounded your written request, the more difficult it is to dismiss.

A well-structured request for sensory or intellectual disability adjustments should:

1. Name the specific diagnostic condition and cite the allied health report confirming it
2. Describe the exact functional impact in the classroom environment
3. List the specific adjustments you are requesting (named, discrete, measurable)
4. Cite the DSE 2005 obligation to make reasonable adjustments enabling participation on the same basis as peers
5. Set a 14-day deadline for a written response confirming the adjustments will be incorporated into the One Plan

If the school does not respond or claims the adjustments are unnecessary, that written non-response is the basis for the next escalation — to the principal, then the Regional Education Director, then the EOC SA or AHRC if necessary.

If you want ready-made templates for requesting sensory adjustments or intellectual disability support plans in writing, the South Australia Disability Advocacy Playbook provides structured demand letters citing the DSE and SA legislation, with fill-in fields for your child's specific circumstances.

The Wait Time Problem

Both sensory processing assessments and intellectual disability assessments typically require an educational psychologist. The SA Department for Education Student Support Services has severe wait times — 38% of students wait more than six months to see an educational psychologist, and some wait up to two years.

Do not wait for a Departmental assessment before requesting adjustments. The DSE does not require a formal Departmental assessment before adjustments are made — it requires the school to consult with you and make reasonable adjustments based on available evidence. If you have a private OT report identifying sensory sensitivities, or a paediatric report confirming intellectual disability, that evidence is sufficient to demand immediate adjustments. Submit it to the school in writing and request a One Plan meeting within two weeks.
