NDIS vs School Funding in WA: What Each System Pays For (and What It Won't)

One of the most persistent misconceptions among WA parents is that the NDIS and school funding are interchangeable — that if the school won't provide an Education Assistant, the NDIS will, or that if the NDIS funds a therapist, the school doesn't need to.

Neither is true. The NDIS and the WA school system are legally separate, funded from separate pools, and designed to cover different parts of a child's life. Confusing them leads to parents chasing the wrong system for support — and children falling through the gap.

The Core Principle: Jurisdictional Boundaries

The National Disability Insurance Scheme (NDIS) was designed to fund disability supports that are the responsibility of the NDIS — community participation, therapy services, assistive technology for daily living, and supports for independent living.

The NDIS is explicitly prohibited from funding supports that are the statutory responsibility of another system — including education. This principle is called the "reasonable and necessary" test combined with the boundary-setting principle in the NDIS Act. Under this framework:

• A school Education Assistant is an educational support — it is the school's responsibility under the Disability Standards for Education 2005 and WA departmental policy. The NDIS does not fund EAs.
• A modified desk or accessible classroom is an educational adjustment — the school funds it.
• A school-based behavior support program is an educational intervention — the school funds it.
• Speech therapy delivered to support communication within school is generally the school's responsibility if it is required to access the curriculum.

This boundary frustrates families, and it is sometimes contested by schools who argue that certain supports fall in gray areas. But the principle is clear: if the support is required for a child to access education, it is the school's obligation to provide it.

What the NDIS Does Fund (That Helps at School)

While the NDIS doesn't fund school-based supports directly, NDIS-funded services create crucial inputs to the school process.

Allied health assessments and reports. A comprehensive occupational therapy (OT), speech pathology, or clinical psychology report funded through the NDIS is the primary evidentiary document parents use to force WA schools to draft rigorous Documented Plans and to substantiate IDA applications. In practice, the NDIS funds the report that makes the school move.

School holiday and after-school supports. NDIS funds can pay for therapy, community participation, social skills programs, and support workers outside school hours. These supports can significantly reinforce skills developed during school time.

Assistive technology for home and community. AAC devices, communication apps, and specialized technology funded through an NDIS plan can be used by the student at home and in community settings. The school may then adopt the same technology as a classroom adjustment — but the school must fund its own setup, not rely on the NDIS device.

Transition supports. For students in their final years of school, NDIS can fund supports that build toward post-school independence — employment preparation, life skills programs, and community access planning. This complements (but does not replace) the school's Individual Transition Plan obligations.

The Private Assessment Problem

Many WA families rely on NDIS funding to cover the cost of private diagnostic assessments. This makes practical sense — private autism and ADHD assessments in Perth cost between $1,900 and $3,100, and the NDIS Capacity Building budget can sometimes be used to fund assessments through registered providers.

The critical point is that a report funded by NDIS and provided to the school is still the school's input for its own planning purposes. The school cannot refuse to accept or act on an assessment report on the grounds that it was funded by NDIS rather than the school's own psychologist. Under the DSE 2005, the school is legally bound to consider private assessments provided by parents, cross-referencing them with internal data before applying for systemic funding.

However, WA DoE and Catholic Education WA (CEWA) have specific requirements around the format and professional signatories of reports they will accept for IDA applications. A report produced by a psychologist alone may not meet the specialist conferral requirement that CEWA, in particular, enforces. Check the specific requirements before commissioning a private assessment with NDIS funds.

The NDIS-at-School Gray Zone

There are specific scenarios where NDIS-funded supports operate within a school environment, and understanding them prevents misunderstandings.

NDIS-funded support workers on school grounds. An NDIS plan can sometimes fund a support worker who accompanies a child into school for activities that fall outside the school's responsibility — for example, supporting community-based learning activities or assisting with personal care needs that exceed what the school's EA is resourced to provide. This is complex, requires formal arrangements between the NDIS, the family, and the school, and is not a substitute for adequate school-funded support.

Therapy on school grounds (funded by NDIS). Speech therapists, OTs, and behavior support practitioners funded by NDIS may visit a school to deliver therapy. This requires a formal arrangement and the school's cooperation. Schools must allow NDIS-funded therapists access to the school environment to deliver supports the NDIS is paying for. However, the school is not required to integrate NDIS-funded therapy into the school's own funded program.

The NDIS does not pay for an EA. This is the specific question that comes up most frequently, and the answer is unambiguous. Education Assistants are an educational support, funded by the WA Department of Education through the student-centred funding model and the IDA. The NDIS will not fund an EA, and a school cannot direct a family to use NDIS funding to supplement the school's EA capacity.

Navigating Both Systems Simultaneously

The practical skill for WA parents is learning to manage both systems in parallel without letting either use the other as a deflection.

The school's argument — "your child's therapist should address that through their NDIS plan" — is sometimes legitimate and sometimes a budget deflection. The test is whether the support relates to accessing the curriculum. If yes, the school owns it. If no, it may be NDIS territory.

The NDIS planner's position — "school supports are the school's responsibility" — is correct, but sometimes used to exclude supports that genuinely sit in NDIS territory because they are being conflated with educational adjustments.

Document both systems separately. Keep your child's NDIS plan goals and the school's Documented Plan goals in separate documents, with clear notes on which system is responsible for each goal. When one system attempts to shift responsibility to the other, that documentation lets you push back with precision.
