Autism and ADHD assessments for children, teens and adults
Assessment for autism, for ADHD, or for both in a single process. Conducted personally by a clinical psychologist in consulting rooms on the Northern Beaches and the Lower North Shore. There is no current waitlist.
AHPRA Registered · Clinical Psychologist · Medicare rebates availableNo current waitlistWe assess for autism and ADHD, separately or together, for children, teenagers and adults. An autism assessment is $2,500. An ADHD assessment is $1,800. A combined assessment covering both is $3,500. There is no current waitlist and a first appointment is usually available within one to two weeks, and your written report follows about four weeks after that. You don't need a referral to get started.
Not sure which assessment you need?
Most people are not, and that is a reasonable position to be in. Autism and ADHD share a good deal at the surface — difficulty holding focus, finding the social side of things hard, feelings that arrive quickly, the ordinary demands of a day taking more out of someone than they seem to take out of everyone else.
Working out which of those is doing what is the assessment, not a prerequisite for booking one. Tell us what you have been noticing when you enquire and we will work out together what fits, including telling you if we do not think an assessment is the right next step.
What we assess
Three assessments, one process each
Autism assessment
$2,500
A comprehensive assessment of social communication, interaction, sensory experience and developmental history, using the ADOS-2 and the ADI-R. It runs across several appointments and draws on information from home and from school or work. You receive a detailed written report and a feedback session to go through what it means and what to do next.
ADHD assessment
$1,800
A structured assessment of capability, attention, focus, activity and impulsivity across the settings a person actually lives in - home, and school or work - using standardised measures alongside information from the people who see them every day. You receive a full written report and a feedback session. We don't prescribe medication; the report gives a paediatrician or psychiatrist what they need if that becomes the next question.
Both, in one process
$3,500
Where both are in question, we assess for both in one process rather than putting someone through two separate assessments. One set of appointments, one clinician, and one report that answers both questions - including how the two presentations interact, which is the part two separate reports can miss. For a child who finds new people and new rooms hard, going through it once instead of twice matters.

What every assessment here includes
One clinician throughout. Dr Halaina Winter conducts every assessment, writes every report and delivers every feedback session. You will not be handed between people.
A comprehensive written report setting out what was assessed, what was found, the reasoning behind it, strengths as well as difficulties, and specific recommendations.
A feedback session to go through the report properly - what is says, what it means, what to do first, and what to tell the school.
Practical next steps, including referrals to occupational therapy, speech pathology or paediatric care where they would help.
What happens, in order
Initial appointment
We talk through what you have been noticing, take a developmental history, and agree what the assessment needs to focus on.Direct assessment
The standardised instruments, administered across one or more appointments depending on which assessment you are having.Information from elsewhere
Questionnaires, and input from teachers and any other professionals already involved.Report and feedback
A detailed written report about four weeks after the first appointment, then a session to talk it through.
How long it takes
There is no current waitlist. A first appointment is usually available within one to two weeks of getting in touch. Your written report follows about four weeks after that first appointment, and the feedback session is booked at the first appointment.
Many Sydney practices currently quote six to twelve months just to begin. It's worth asking any practice you contact about both - the wait to start, and the wait for the report after that.
Where assessments happen
In consulting rooms
Assessments are conducted in our consulting rooms on the Northern Beaches and the Lower North Shore. We can schedule your in-person appointments for a location that works for you and the address for your appointments is confirmed when you book.
By arrangement, where there is a clinical reason
Where there is a clinical reason to assess someone in their own environment, we can arrange to come to you - at home, at daycare or at school. The instruments and the report are the same; only the setting changes. Travel is charged in addition to the clinic fee, and quoted when you enquire. Read about mobile assessment.

Assessments are private pay. NDIS funding cannot be used for a diagnostic assessment, whether you are seeking access to the NDIS or already have a plan, diagnostic assessment is not capacity building. If you are applying for the NDIS, this assessment that evidences your application is paid for privately.
There is one exception. For a person under 25 with a referral from a paediatrician or consultant psychiatrist, Medicare provides a partial rebate towards an autism assessment under its complex neurodevelopmental disorder items. There are no Medicare rebates for an ADHD assessment.
Fees are current as at August 2026.
FAQs before you get in touch
-
No. You can contact us directly. A referral only becomes relevant if you're seeking a Medicare rebate for an autism assessment, which requires a referral from a paediatrician or consultant psychiatrist for a person under 25.
-
You don't have to know. Tell us what you're noticing and we'll work it out together before anything is booked - including telling you if we think an assessment isn't the right next step.
-
No. Diagnostic assessment isn't capacity building, so it can't be funded through an NDIS plan unless you have a specific budget for assessments. Assessments are usually always private pay. NDIS funding can be used for psychological therapy.
-
A first appointment is usually available within one to two weeks. Your written report follows about four weeks after that.
-
No. Dr Halaina Winter is a Clinical Psychologist, not a medical practitioner, and does not prescribe. Where medication is a question, the assessment report gives a paediatrician or psychiatrist what they need to consider it.
-
Yes. We assess adults for autism, for ADHD, or for both together.
