Intellectual Disability and School Support in Australia: NDIS, NCCD, and Reasonable Adjustments

Two Systems, One Student: How Australian School Disability Support Works

Australian families navigating school support for a child with an intellectual disability face a system split across two frameworks that don't always communicate: the school's obligations under the Disability Standards for Education 2005 (DSE), and the student's individual National Disability Insurance Scheme (NDIS) plan.

The DSE, enacted under the Disability Discrimination Act 1992, requires schools to provide reasonable adjustments so that a student with a disability can participate in education on the same basis as a student without a disability. The NDIS provides individually funded supports — therapy, allied health, assistive technology, capacity building — that sit alongside what the school provides but don't replace it.

Understanding what falls on each side is essential. Schools are responsible for curriculum adjustments, teacher aide time, modified assessments, and the educational components of support. The NDIS funds therapy (speech, OT, psychology), equipment, and capacity-building supports that aren't part of the school's core educational obligation. The overlap zone — where a therapy goal supports an educational outcome — is where confusion and gaps appear.

The NCCD: How Funding Follows Adjustments

Every Australian school, government and non-government, participates in the Nationally Consistent Collection of Data on School Students with Disability (NCCD). The NCCD categorises each student's level of adjustment into four tiers:

1. Support provided within quality differentiated teaching practice (QDTP) — universal adjustments available to all students.
2. Supplementary adjustments — targeted adjustments beyond standard classroom practice, such as modified tasks, additional teacher aide time, or specialised resources.
3. Substantial adjustments — significant modifications requiring considerable staff time and resources, often including individual learning plans and regular specialist input.
4. Extensive adjustments — high-level, individualised supports often involving full-time aide support, specialised curriculum, and intensive allied health input.

The NCCD level is based on the adjustments a student receives and the functional impact of disability, not on diagnosis alone. The NCCD counts students by category and adjustment level to inform school funding; it does not set an earmarked amount for an individual child. If the school records the wrong level or fails to document adjustments, ask what evidence supports its NCCD record and whether it should be reviewed.

Parents can ask the school what NCCD level their child has been classified under. If the level doesn't match the intensity of support the child needs, that's a conversation to have with the school and, if necessary, the education department.

Reasonable Adjustments: What Schools Must Do

Under the DSE, a school must make reasonable adjustments unless doing so would impose unjustifiable hardship on the school. The adjustment must be related to the student's disability and aimed at ensuring the student can participate in education on the same basis as other students.

For a student with an intellectual disability, reasonable adjustments typically include:

• Modified curriculum content aligned with the student's learning level while maintaining access to the same learning areas as peers
• Individual Learning Plans (ILPs) or equivalent documents that set specific, measurable goals
• Additional teacher aide time, particularly during literacy and numeracy instruction
• Modified assessment tasks that assess the same learning outcomes through different methods
• Assistive technology such as text-to-speech software, AAC devices, or visual supports
• Environmental adjustments — seating, noise management, visual schedules

Schools cannot refuse to enrol a student with an intellectual disability based on disability alone. The DSE requires access and participation on the same basis as peers, with reasonable adjustments unless they would impose unjustifiable hardship; it does not impose a nationwide mainstream-first placement test. Ask the school how the proposed setting will meet the student's access and participation needs.

Thriving Kids: What's Changing for Younger Children

The first phase of Thriving Kids supports began on 1 October 2026 for children aged 8 and under with developmental delay and/or autism and low-to-moderate support needs. Supports are rolling out nationally and across states and territories, with full rollout scheduled by 1 January 2028. NDIS access and eligibility rules do not change until 1 January 2028, so children are not transitioning out of NDIS packages under the October 2026 launch.

Children with permanent and significant disability or high support needs can continue to access the NDIS, subject to usual eligibility arrangements. An intellectual-disability diagnosis or a school's NCCD adjustment level alone does not establish NDIS eligibility.

For parents, this means:

• A child with developmental delay who currently receives NDIS-funded speech and occupational therapy remains subject to the current access rules until 1 January 2028; after the new arrangements begin, eligibility will be assessed under those arrangements.
• A school adjustment level or intellectual-disability diagnosis does not by itself determine whether a child meets NDIS access criteria; use the NDIS eligibility process and the child's individual evidence.
• The national rollout is gradual, with all supports planned to be in place by 1 January 2028. Check what is available in your state or territory.

State and Territory Variations

Education is primarily a state and territory responsibility in Australia, so the implementation of disability support varies:

New South Wales: The Department of Education operates Integration Funding Support (IFS) for government schools, with staffing allocations based on assessed need. The Disability, Learning and Support section provides specialist guidance.

Victoria: The Disability Inclusion funding and support model is now in place in all Victorian government schools. It includes school-level and student-level funding informed by the Disability Inclusion Profile. The department no longer accepts PSD applications, although existing PSD eligibility continues to be processed.

Queensland: State schools use Reasonable Adjustment Resourcing (RAR), phased in from 2023 to 2025 as the Education Adjustment Program (EAP) was phased out. RAR bases resourcing on the level of adjustment a student needs to participate in education, rather than requiring verification under a fixed list of disability categories.

Western Australia: Public schools receive Individual Disability Allocation (IDA) funding for eligible students. Education Support Centres and Schools provide specialised settings for students with significant intellectual disabilities. The DSE does not impose a nationwide mainstream-first placement test.

South Australia and Tasmania operate similar models with varying terminology and funding mechanisms.

Regardless of state, the DSE applies nationally. A school in any jurisdiction that refuses to make reasonable adjustments for a student with an intellectual disability may be in breach of the Disability Standards for Education, and a complaint can be lodged with the Australian Human Rights Commission.

Getting Help With Your Child's School Plan

The Intellectual Disability IEP & Placement Playbook includes a cross-jurisdictional framework covering Australian DSE obligations alongside US, UK, and Canadian equivalents. The core strategies — challenging low expectations, demanding evidence-based instruction, securing access and participation, and monitoring progress through data — translate across systems, while placement tests differ by jurisdiction.

Whether you're questioning your child's NCCD level, pushing back on a recommendation to move from mainstream to a special school, or making sure the school's adjustments align with the NDIS plan, the playbook gives you the organised approach to advocate effectively. Get the complete playbook.
