NCCD Explained for Victorian Parents: How It Affects Your Child's School Support

Every year, your child's school submits data to the Australian government recording whether your child has a disability and, if so, what level of educational adjustment they are receiving. This is called the Nationally Consistent Collection of Data on School Students with Disability (NCCD). Parents rarely hear about it by name, but it directly shapes how much funding flows to schools and how your child's needs are classified in the system.

What Is the NCCD?

The Nationally Consistent Collection of Data on School Students with Disability (NCCD) is an annual census, collected in August each year, across every Australian school — government, Catholic, and independent. It records:

• Whether each student has a disability (using a functional, educational definition)
• The level of adjustment the school is providing to that student

The data goes to the Australian Department of Education and feeds into the federal loading for students with disability that is distributed to states, sectors, and eventually schools. In 2024, 1,062,638 Australian school students — 25.7% of total enrolments — were recorded on the NCCD as receiving an educational adjustment. This figure has risen steadily from 18.0% in 2015, reflecting both increased awareness and improved identification processes.

In Victoria, the NCCD data also feeds directly into the Disability Inclusion (DI) funding model. A student's placement at a particular NCCD adjustment level is the basis on which the school reports to DET and, for students with complex needs, informs the Disability Inclusion Profile process.

The Four NCCD Adjustment Levels

The NCCD categorises support into four levels. Each represents a progressively higher intensity of adjustment. Understanding these levels matters because they determine how the school is describing your child's needs in official data, and because the DIP process uses these levels to assess whether Tier 3 individualised funding is warranted.

1. Quality Differentiated Teaching Practice (QDTP)

This is the baseline. QDTP describes the adjustments a skilled teacher makes for a broad range of students as part of good, differentiated classroom practice. Examples include:

• Preferential seating at the front of the room
• Providing written instructions alongside verbal ones
• Breaking tasks into shorter steps
• Allowing brief movement breaks

Students coded at QDTP level on the NCCD are receiving adjustments, but nothing beyond what a well-resourced classroom teacher provides as standard practice. A student at this level is unlikely to qualify for Tier 3 Disability Inclusion funding.

2. Supplementary Adjustments

Supplementary adjustments are targeted supports provided at specific times, beyond normal classroom differentiation. Examples include:

• Extra time on formal assessments
• A visual schedule personalised to the student
• Intermittent integration aide support for specific subjects or tasks
• Scheduled check-ins with the learning support coordinator

Students coded at Supplementary are receiving support that is clearly beyond standard classroom practice, but this support is occasional or targeted rather than constant.

3. Substantial Adjustments

Substantial adjustments involve frequent, specialised support on most days. Examples include:

• Heavily modified curriculum materials
• Regular therapeutic intervention delivered within school (e.g., weekly speech pathology sessions during school time)
• An active behaviour support plan with specific staff training
• Daily aide support for multiple subjects

Students coded at Substantial typically have significant functional barriers to learning. This level is relevant to the Disability Inclusion Profile process — a student who has required Substantial adjustments for at least 10 weeks is potentially eligible for the DIP meeting.

4. Extensive Adjustments

Extensive adjustments are constant, pervasive, and highly individualised. This level is for students who cannot function in a school environment without continuous, specialised support. Examples include:

• Full-time one-on-one physical assistance for self-care and mobility
• Constant supervision for severe behaviours of concern
• Full-time AAC (Augmentative and Alternative Communication) support
• Continuous medical monitoring during school hours

Students coded at Extensive almost always require Tier 3 Disability Inclusion funding.

Why NCCD Coding Matters for Your Child

The NCCD is not just a data collection exercise. It has practical consequences:

Funding implications: Federal government funding for students with disability is distributed partly based on NCCD data. Schools that accurately identify and record their students with disability receive more funding than those that under-identify.

DIP eligibility: To be eligible for a Disability Inclusion Profile meeting (which determines Tier 3 funding), DET policy requires that the student has been recorded at Supplementary, Substantial, or Extensive adjustment level for at least 10 consecutive weeks. If your child is only being coded at QDTP, they may not meet the DIP eligibility threshold even if their needs clearly warrant individualised support.

Evidence for VCAA: For VCE students seeking Special Examination Arrangements, the NCCD adjustment level and the school's documented history of providing adjustments forms part of the evidence base the VCAA reviews.

How Schools Determine NCCD Coding

The NCCD is moderated within each school, typically by the principal and learning support coordinator. For each student with a disability, the school must determine:

1. Does this student have a disability under the functional, educational definition? (This is broader than a medical diagnosis — it includes any condition that substantially limits participation in the same way as peers.)
2. What is the highest level of adjustment the school is currently providing or planning to provide?

Critically, NCCD coding is meant to reflect the actual adjustments being provided, not the student's diagnosis. A student with ASD who only needs preferential seating should be coded at QDTP. A student with the same diagnosis who requires a full-time integration aide and a modified curriculum should be coded at Extensive.

What to Do If You Believe Your Child Is Being Under-Coded

Under-coding is a real problem. Some schools inadvertently code students at QDTP when the actual support being provided (or that should be provided) clearly meets the Supplementary or Substantial threshold. Under-coding has two negative consequences: it reduces the school's funding allocation and it may prevent your child from becoming eligible for the DIP process.

If you believe your child's support needs are being under-represented in the NCCD:

1. Request a copy of your child's NCCD classification from the school. Schools should be willing to share this with parents.
2. Review the four levels and assess which most accurately reflects what your child requires.
3. Raise it at the SSG meeting. Bring a written description of your child's current support needs and ask whether the NCCD classification reflects those needs. Frame this as a collaborative review, not an accusation.
4. Reference the NCCD data collection guidelines, which are publicly available from ACARA (the Australian Curriculum, Assessment and Reporting Authority).

The Victoria Disability Support Blueprint includes a plain-language NCCD explanation and a guide to preparing for SSG discussions about adjustment levels and DIP eligibility — essential context for any parent navigating the Victorian school funding system.
