School Not Following the One Plan SA: What Parents Can Do
School Not Following the One Plan in SA: A Step-by-Step Response Guide
You sat through the meeting. You negotiated the goals. The One Plan was signed. Then three weeks later, nothing has changed — the adjustments aren't happening, the SSO isn't there, and the school acts as though the document doesn't exist. This is one of the most common and most frustrating experiences reported by South Australian parents of children with disabilities, and it is not something you have to accept.
A signed One Plan is not a statement of good intentions. It is a document that triggers legal obligations. When a school fails to implement it, that failure is measurable, documentable, and challengeable — and there is a clear sequence of steps you can take right now.
What the One Plan Is Actually For (and Why Schools Often Ignore It)
The One Plan replaced the old Negotiated Education Plan (NEP) as the Department for Education's mandatory personalised learning document for students with disabilities. Under departmental guidelines, it must record the student's strengths and aspirations, learning priorities aligned with the curriculum, the adjustments planned to support access, and any services provided by external agencies.
In practice, independent reviews — including stakeholder testimony gathered during the SA inquiry into suspensions and exclusions — have described the One Plan as a "tick a box sort of a procedure" where tracking outcomes between iterations is rarely undertaken. Parents are brought in, goals are written in vague language, and then the document is filed away until the next annual review.
The problem is compounded by the way support is funded. Since 2024–2025 reforms, most students at the lower funding tiers (Categories 1–3) are covered by an automated "IESP Supplementary Level Grant" delivered as block funding to the school. There is no line-item in the school's budget labelled "[Your Child's Name] — SSO hours". That opacity makes it very easy for a school to quietly dilute targeted support into general classroom use and claim everything is fine.
But "quiet" does not mean lawful. Under the Disability Standards for Education 2005 (Cth) (DSE), schools must make — and maintain — reasonable adjustments. The obligation is not to write them down once. It is to actually deliver them.
Step 1: Document the Breach Before You Raise It
The single biggest mistake parents make is approaching the school verbally while the gap is ongoing. Verbal complaints are met with verbal reassurances. Nothing changes, and there is no record.
Before you send any letter or request any meeting, spend one to two weeks building a written record. Note the date, the adjustment that should have occurred, and what actually happened instead. For example:
- Monday 28 April: One Plan requires sensory break at 10.30am facilitated by SSO. Child reports no break occurred. No SSO present in class.
- Wednesday 30 April: One Plan requires chunked written instructions. Teacher sent home full-page unmodified worksheet.
This is your evidence base. Keep it in a dated document — a simple notes file or a spreadsheet works. The more specific it is, the more difficult it is for the school to dismiss.
At the same time, gather the original signed One Plan, any allied health reports that informed the plan, and any previous emails about the adjustments. You need to be able to show exactly what was agreed and when.
Step 2: Request Evidence of Implementation in Writing
Your first formal move is an email to the classroom teacher and inclusion coordinator that does two things: signals that you are monitoring implementation, and creates an opening for the school to explain itself.
Write something along these lines: "I am writing to request an update on the implementation of [child's name]'s current One Plan, dated [date]. Specifically, I would like to understand how the following adjustments have been delivered over the past [X] weeks: [list each adjustment]. Could you please provide a written summary of how each adjustment has been implemented, along with any records showing delivery?"
This email does not accuse anyone of anything. It asks for evidence. The response — or the absence of one — tells you what you need to know. If the school provides evidence you were not aware of, you can revisit your records. If they cannot, you now have a written acknowledgement of the gap.
Under the DSE, schools are required to consult with parents as ongoing partners in the adjustment process. Requesting implementation evidence is a normal extension of that consultation right — not an aggressive act.

Step 3: Send a Formal Letter of Concern to the Principal
If the evidence of non-implementation is clear, your next step is a formal letter to the principal. This is not a complaint (that comes later if needed). It is a structured letter of concern that forces the school into an accountable response.
An effective letter of concern for One Plan non-implementation contains five components:
The legal anchor — cite the DSE 2005, specifically the obligation to make and maintain reasonable adjustments to enable the student to participate "on the same basis" as peers without disabilities. You can also cite the DfE's own inclusive education policy, which incorporates the DSE requirements.
The evidence — reference the signed One Plan (attach a copy) and your specific record of the adjustments that have not been delivered. Keep this factual and dated. Do not use language like "the school doesn't care" — use language like "the following adjustments, as recorded in the One Plan dated [date], have not been observed on the following dates."
The gap — articulate the impact. What is your child experiencing as a result of the unimplemented adjustments? Academic regression? Increased anxiety? Behavioural dysregulation at school or at home? This is where the human cost of non-compliance becomes part of the official record.
The actionable demand — state exactly what you require. A remediation meeting within seven days. A written implementation plan. Immediate reinstatement of the SSO hours. Be specific.
The deadline — impose a written response timeframe. Ten to fourteen working days is standard. State that if you do not receive a response by that date, you will escalate the matter to the regional Education Director.
Send the letter by email so you have an automatic timestamp and delivery record. Address it to the principal directly, and copy the inclusion coordinator.
If you need ready-to-use letters structured around SA legislation and DfE policy, the South Australia Disability Advocacy Playbook includes a complete non-implementation letter template with fill-in sections for each of the five components above.
Step 4: Use the NCCD Classification as Leverage
Most parents are unaware of the connection between NCCD data and school funding — but it is one of the most powerful advocacy tools available.
Schools classify each student receiving disability support into one of four NCCD levels: Quality Differentiated Teaching Practice, Supplementary, Substantial, or Extensive. These classifications are reported annually to the federal government and drive funding allocations. If your child is classified as "Substantial" — meaning frequent, highly individualised adjustments are required — you can request to see the documented evidence of those substantial adjustments being delivered.
Put it plainly in writing: "The school has classified [child's name] at the Substantial NCCD level for [year]. I request to see the documentation showing that substantial daily adjustments have been consistently delivered, as required to justify this classification."
This puts the school in an uncomfortable position. Either they produce evidence that adjustments are occurring — which means the One Plan is being followed — or they cannot, which confirms the breach. Either way, it moves the conversation from your word against theirs to an institutional record-keeping question.
Step 5: Escalate to the Regional Education Director
If your letter to the principal is ignored or met with an inadequate response, your next step is the regional Education Director. The Director oversees a cluster of schools and has the authority to mandate compliance and mediate disputes at the site level.
Your escalation letter to the Director should attach the full paper trail: the signed One Plan, your implementation request, any response from the school, your evidence record, and your letter of concern. Summarise the sequence of events in chronological order.
The Department for Education's formal complaint management policy also allows you to lodge a centralised complaint via the Customer Feedback Team (phone 1800 677 435). Doing both — emailing the Regional Director and lodging a formal complaint — simultaneously signals that you are operating within the system's own accountability framework.
If internal escalation does not resolve the matter, the next tier involves external bodies: the Equal Opportunity Commission SA under the Equal Opportunity Act 1984 (SA), or the Australian Human Rights Commission under the Disability Discrimination Act 1992 (Cth). These pathways are covered in detail in the post on external complaints against SA schools.
What a Legally Sound One Plan Actually Requires
One important tactical note: many One Plans are not legally sufficient documents even before the question of implementation arises. Vague goals like "Student will improve social skills" are essentially unenforceable because there is no measurable standard against which to assess delivery.
When you next review the One Plan, push for SMART goals — Specific, Measurable, Achievable, Relevant, and Time-Bound. A properly written goal looks like: "During recess, the SSO will facilitate a structured peer-play programme for 15 minutes, three times per week, to assist the student in initiating conversations, achieving a 70% success rate by the end of Term 2." That goal can be monitored. It can be evidenced. And non-delivery is immediately visible.
The distinction matters because if the One Plan contains vague goals, a school can claim the goals are being "addressed" without providing any specific support. Forcing SMART language into the document is the first step to making non-implementation provable.
The South Australia Disability Advocacy Playbook includes a SMART goal bank specifically designed for the SA curriculum, along with templates for requesting One Plan reviews and documenting implementation failures.
The Main Things to Remember
Schools are not automatically compliant with the documents they create. Holding them accountable requires a written paper trail, specific legal citations, and a willingness to escalate when initial requests are ignored.
The sequence is: document the breach before raising it, request evidence of implementation in writing, send a formal letter of concern to the principal with a deadline, use NCCD data as a leverage point, and escalate to the Regional Director if the principal does not respond adequately.
Throughout this process, every communication should be in writing, every request should carry a deadline, and every letter should cite the DSE 2005 by name. Schools are bureaucratic institutions that respond to statutory obligations. When you write in the language of those obligations, you change the dynamic.
