WA School Psychology Assessment and the CDS Waitlist: How to Get Support While You Wait

If you have tried to access the WA Child Development Service recently, you already know the situation. As of July 2025, there were 25,320 children on the CDS waitlist, with families facing wait times of up to 3.5 years to see a paediatrician. The 2024–25 State Budget committed $39 million to expand the service, but the immediate reality is that tens of thousands of WA children are waiting for the formal diagnoses their schools require to unlock targeted funding and accommodations.

This waitlist is not just an inconvenience. For many families, it functions as a systemic gatekeeper — schools routinely use the absence of a formal diagnosis as a reason to delay developing Documented Plans, applying for Individual Disability Allocation funding, or implementing the kind of structured adjustments that could be making a meaningful difference right now.

Here is what parents actually have available to them while they wait, and how to use those options effectively.

The Child Development Service: What It Is and What It Covers

The WA Health Child Development Service (CDS) provides free, multidisciplinary assessment for children in the Perth metropolitan area. The team includes paediatricians, speech pathologists, occupational therapists, and clinical psychologists. For families who can access it, the CDS produces the kind of comprehensive assessment documentation that schools need for IDA funding applications — a paediatrician's report, allied health reports detailing functional impact, and diagnostic conclusions that use the clinical language the Department of Education's rubrics require.

Regional access is provided through the WA Country Health Service, which operates Child Development Services in regional areas. However, specialist shortages in the Pilbara, Goldfields, Kimberley, and other remote areas mean that regional families often face even longer effective wait times than the already-extended metropolitan figures suggest.

The CDS is the right long-term goal for families who need a formal diagnosis and cannot access or afford private assessment. But the wait cannot be an excuse for zero interim support at school.

The School Psychology Service: A Different Pathway

Western Australia's School Psychology Service (SPS) operates as part of the Department of Education, with approximately 253 full-time equivalent psychologists across more than 800 public schools. These are not the same as the CDS. A school psychologist is an employee of the Department, based within the school or regional office structure, and their role spans a range of functions: whole-school wellbeing programs, critical incident response, individual student assessment, and support for teachers implementing Documented Plans.

This means their availability for individual cognitive and educational assessments — the kind that would inform an IDA application or support the development of a detailed IEP — is often stretched. Schools draw on school psychologists for many purposes, and one family's request for a formal educational assessment joins a queue of competing demands.

Despite this, requesting a school psychology assessment is a legitimate and underused tool. Making the request in writing, addressed to both the principal and the Lead School Psychologist at your WA regional office, creates a formal record and requires a formal response. The assessment does not produce a medical diagnosis, but it can:

• Establish the child's current functional capacity in cognitive and academic domains
• Provide documented evidence of significant discrepancy between ability and achievement
• Support the development of a detailed IEP with specific, measurable goals
• Provide interim documentation for an EAA-funded support package while the CDS waitlist runs its course

A school psychologist assessment will not, on its own, satisfy the IDA application requirements that require a formal medical or clinical psychology diagnosis. But it is not nothing — it is evidence that the school can use to justify support funded through EAA, and it is documentation that forms part of your overall evidence record.

Your Rights While Waiting: No Diagnosis Does Not Mean No Support

This is the central point many WA families do not know: schools are not permitted to use "waiting for a diagnosis" as justification for providing no support at all.

The WA Department of Education's Students at Educational Risk (SAER) policy applies to students who are performing significantly below their peers, or who present with substantial attendance or behavioural concerns — regardless of diagnostic status. If your child is visibly struggling in class, displaying behaviour that teachers recognise as atypical, or failing to access the curriculum on the same basis as their peers, the school has an obligation under SAER to respond.

That response should take the form of a Documented Plan — an IEP focused on academic adjustments, an Individual Behaviour Plan, or a Risk Management Plan depending on the presenting concerns. Demanding a Documented Plan does not require a diagnosis. It requires observed functional need, and in the meantime, schools can fund interim support through EAA.

The Educational Adjustment Allocation does not require a formal IDA application. Principals have discretion to deploy EAA funds to hire additional EA hours, purchase assistive technology, or access specialist consultants — and they can do this based on observed need rather than a completed diagnostic assessment. If the school is resisting interim support on the basis that your child does not yet have a formal diagnosis, that resistance is not well-founded in policy.

Private Educational Psychologists: When You Have the Financial Means

For families who cannot wait and can afford it, private educational psychologists are the fastest pathway to the kind of documented assessment that unlocks school support. Private psychologists in Perth — including services like Perth Evaluation and Consultancy Services (PECS) and Clear Health Psychology — provide WISC-V and WIAT-III assessments that produce clinical reports in the format that schools and the Department of Education recognise.

Regional families are not entirely without options either: organisations like In3Minds in Geraldton provide psychology services in the Mid West region, and telehealth has expanded access to some forms of assessment for remote families.

The cost is significant — comprehensive psycho-educational assessments from private practitioners typically run to several hundred to over a thousand dollars depending on the scope — and for families already under financial pressure this is not a realistic option. But if you have NDIS funding, check whether "assessment and reports" can be funded through your child's plan as a support that enables reasonable and necessary supports to be identified. This is worth a conversation with your NDIS planner or Local Area Coordinator.

Making the Waitlist Work for You Strategically

The CDS waitlist, for all its frustrations, is not completely passive time. Use it strategically:

Document everything now. Teacher comments, behavioural incidents at home, things your child says about school — all of this becomes evidence. A dated journal of functional observations, written consistently from today, will be valuable both for the eventual assessment process and for any formal advocacy conversations with the school.

Engage the school in writing. Request the SSG meeting, request the school psychology assessment, request a Documented Plan. Every request in writing and every response (or non-response) from the school becomes part of your record.

Ask for telehealth specialist access. For children in regional WA who are still waiting, the school can be asked to use EAA funds to access telehealth speech pathology or occupational therapy while the CDS waitlist runs. The WA Country Health Service also coordinates visiting specialists in regional areas.

Seek an interim Documented Plan. Ask the school explicitly to develop an IEP or IBP based on current observed needs, with an agreed review date once the formal assessment is complete. This is consistent with SAER policy and ensures your child is not in a support vacuum for three years.

If you are navigating the WA assessment maze and the school system simultaneously, the Western Australia Disability Advocacy Playbook covers the specific documentation required for IDA applications, the SAER-based interim support request process, and the escalation pathway when the school is not responding appropriately to observed need.
