How Much Does an ADHD Assessment Cost in Sydney?

There is no single fee that applies to every ADHD assessment. The overall cost can depend on the person being assessed, the information that needs to be gathered, and the level of assessment and reporting required.

For children and adolescents, PsychWell begins with an initial screener consultation with a parent or guardian. This helps us develop a clearer understanding of the presenting concerns, the child’s history and current difficulties, and whether ADHD or other factors may be contributing.

For adults, PsychWell also begins with an initial screener consultation. This provides an opportunity to explore current concerns, relevant history and symptoms, and how these may be affecting everyday life, relationships, study or work.

The screener is an important first step because difficulties with attention, concentration, organisation or emotional regulation do not always have one explanation. For both adults and children, ADHD symptoms may overlap with, or occur alongside, anxiety, stress, trauma or PTSD, autism, learning difficulties, mood-related concerns, or other psychological or developmental factors.

Psychometric Assessments


Following the screener, our Educational and Developmental Psychologist can discuss the findings and recommend the most appropriate next steps. Further assessment is not always the only pathway. Depending on the individual’s needs, recommendations may include an ADHD assessment, a broader cognitive or academic assessment, psychological therapy, ADHD coaching, practical strategies and supports, or another appropriate pathway. In some circumstances, a combination of assessment and ongoing support may be recommended.

Where further assessment is appropriate, the pathway can be tailored to the questions that need to be answered. This may include an ADHD assessment, an ADHD and cognitive assessment, or an ADHD, cognitive and academic assessment where broader learning, educational or developmental concerns are also present.

We understand that accessing an assessment can be a significant financial commitment for individuals and families. Payment plan options are available to help make the assessment process more accessible. Please speak with our team if you would like to discuss the options available.

When comparing assessment providers, it can therefore be helpful to look beyond the initial price. Understanding what is included in the assessment, the level of reporting provided, and whether the assessment and recommendations address your particular concerns can help you compare services more meaningfully.

What is Included in an ADHD Assessment?​

A comprehensive ADHD assessment is designed to bring together different sources of information rather than relying on a single test. The exact process can vary depending on the individual’s age, circumstances, and assessment requirements.

1. Initial Screener 

For children and adolescents, the process begins with an initial screener consultation with a parent or guardian. This allows the psychologist to explore developmental history, current concerns and everyday functioning, and consider whether ADHD or other factors may be contributing to the child’s presentation.

A Mental Health Care Plan and referral from your GP can be used for the initial screener consultation, allowing eligible families to access a Medicare rebate.

Following the screener, the psychologist will discuss whether further assessment is recommended and which assessment pathway may be most appropriate.

For adults, the assessment process explores current concerns and developmental history, including how attention, organisation and related difficulties may affect everyday functioning, relationships, study or work.

2. Questionnaires and Assessment Tools

Questionnaires and standardised assessment tools provide further information about attention, behaviour and everyday functioning.

For children and adolescents where ADHD is the primary concern, the ADHD assessment includes a structured DIVA interview, Conners-4 questionnaires and a feedback session.

Where there are additional concerns regarding thinking, learning or memory, cognitive assessment using the WISC-V may also be recommended.

Where there are broader learning or school concerns, the assessment may also include the WIAT-III to assess academic skills such as reading, writing, spelling and mathematics.

This means the assessment can be tailored to the questions that need to be answered rather than applying the same testing process to every child.

3. Written Diagnostic Letter or Report and Recommendations

A diagnostic letter or report brings together the information gathered throughout the assessment. Rather than simply presenting test results, it can help explain the findings in the context of the individual’s everyday experiences.

The letter or report may also include personalised recommendations and practical strategies that might be considered at home, school, or work, depending on the person’s circumstances.

PsychWell offers different reporting options depending on the individual’s needs.

A Diagnostic Letter provides a concise summary of the assessment findings, diagnostic outcome where appropriate, recommendations and next steps.

A Comprehensive Diagnostic Report provides more detailed assessment findings and interpretation of results, diagnosis where appropriate, and recommendations for home, school and treating professionals.

4. Feedback Session

A feedback session allows you to discuss the assessment findings, ask questions, and understand the recommended next steps. This can be an important part of the process, particularly if you have spent a long time trying to make sense of difficulties with attention, organisation, time management, or other aspects of everyday life.

Why Does a Comprehensive Assessment Matter?

When considering ADHD assessment cost in Sydney, it can be tempting to compare providers based solely on price. However, it is also important to understand what is actually included in the assessment.

Difficulties with attention and concentration may sometimes occur alongside cognitive or learning difficulties. For some children, an ADHD-focused assessment may be appropriate. For others, broader cognitive or academic assessment may provide important information about their strengths, challenges and learning needs.

At PsychWell, the assessment pathway is therefore guided by the individual’s presentation rather than assuming that every person requires exactly the same assessment.

This can provide more meaningful insight into a person’s strengths and challenges while helping identify practical strategies and support options for the future.

Does the Assessment Process Differ for Children and Adults?

Yes. While the overall aim is to develop a clearer understanding of attention, focus, and everyday functioning, the information gathered may differ depending on age.

When it comes to children and adolescents, parents, caregivers, and teachers may provide valuable information about development and behaviour across different environments. Adult assessments however place greater emphasis on developmental history and the ways attention, organisation, and executive functioning affect work, relationships, and everyday life.

PsychWell takes a personalised approach, tailoring the assessment process to the individual rather than applying the same process to everyone.

Frequently Asked Questions

The cost varies depending on the individual and the assessment requirements. PsychWell does not list one fixed ADHD assessment fee, so the best way to find out the current cost is to contact the practice and discuss your circumstances.

The length of an assessment may vary depending on the individual and the required assessment components. PsychWell can explain what the process involves and how much time it may take when you enquire.

A GP referral is not required to contact PsychWell or arrange an ADHD assessment.

However, for the initial screener consultation, a Mental Health Care Plan and GP referral can be used to access a Medicare rebate for eligible clients.

The subsequent ADHD assessment is separate from the Mental Health Care Plan.

Both a Diagnostic Letter and a Comprehensive Diagnostic Report provide valuable information following an assessment. The right option will depend on your individual needs, what has been identified during the assessment, and what you need the documentation for.

A Diagnostic Letter provides a clear and concise summary of the assessment findings, diagnosis where appropriate, recommendations and next steps. It has a lower reporting cost than a Comprehensive Diagnostic Report and may be suitable when a summary of the diagnosis and assessment outcome is all that is required.

A Comprehensive Diagnostic Report provides a more detailed understanding of the assessment findings, including interpretation of results, diagnosis where appropriate, and more extensive recommendations. It may be recommended where assessment needs are more complex or where greater detail would be helpful for treatment, educational planning, school supports or other services.

Which option is right for you really depends on what you need the documentation for. If the assessment is being requested by a school, treating professional or another service, it can be helpful to check what type of documentation they require. Our Educational and Developmental Psychologist can also talk you through the options and help you decide which type of report best meets your needs.

A Mental Health Care Plan and GP referral can be used for the initial screener consultation for eligible clients, allowing a Medicare rebate to be claimed.

Medicare eligibility depends on the particular service, referral arrangements and individual circumstances. Our team can explain this when you enquire.
