At ADAP, we believe an assessment that combines the knowledge of assessors across both speech pathology and psychology disciplines is critical to an accurate assessment and the best outcome and recommendations for the children and young people we see.
We accept referrals for an Autism assessment from Paediatricians and Psychiatrists. Currently, ADAP will also accept referrals directly from parents where concerns are evident and supported by another professional, such as a day care educator, teacher, school psychologist, general practitioner, other medical specialist or therapist working with your child (e.g., speech pathologist, psychologist, occupational therapist, social worker physiotherapist).
We understand that seeking an assessment can feel overwhelming. Our process is designed to be thorough, respectful, and as straightforward as possible. We collect information from multiple sources to build a clear picture of your child’s strengths and needs.
Much of this information is collected before your appointment. In many cases, we’re able to provide feedback on the day. If this isn’t possible, and additional information is needed, a feedback session will be scheduled within a few days or this occurring. If needed, additional cognitive or language assessments may be included.
You’ll receive a written report within 10–15 working days.
Here is a guide to what you can expect:
Intake and Information Gathering
The assessment begins before we meet your child. Gathering background information helps us understand them in the context of their everyday life.
Parent/Caregiver Questionnaires: You’ll be asked to complete detailed questionnaires about your child’s development, behaviour, and daily life at home.
Questionnaires from Other Settings: With your permission, we’ll send questionnaires to your child’s daycare and/or school, to understand how they interact and function in those environments.
Reviewing Existing Reports: We will request relevant reports from other professionals involved in your child’s care (such as paediatricians, speech pathologists, or occupational therapists).
In-Person Assessment
This is when you and your child meet with our clinicians. The session is tailored to your child’s age and needs, using well-established assessment tools.
Direct Interaction: We spend time working directly with your child using one of the following assessments:
Additional Assessment (if needed): In some cases, we may also complete a school or daycare observation, or include cognitive and/or language assessment, to build a more complete understanding of your child’s profile.
We will accept referrals directly from parents where concerns are evident and supported by another professional, such as a day care educator, teacher, school psychologist, general practitioner, paediatrician or psychiatrist, or other medical specialist or therapist working with your child (e.g., speech pathologist, psychologist, occupational therapist, social worker, physiotherapist). If a diagnosis of autism is made, this is in line with the National Guidelines for the Assessment and Diagnosis of Autism in Australia and meets WA Education and NDIS requirements.
In some instances, your child may have seen a paediatrician or psychiatrist first who refers for the assessment. While children and young people can now be diagnosed with autism without seeing a paediatrician or psychiatrist at the time, many children will continue to have (and need) the valuable input of these medical specialists, particularly where the child may have more complex medical and/or developmental concerns. If we feel your child may benefit from their input, we will discuss this with you.
Our assessment process allows us to collect information about the child across different environments and includes:
Working directly with the child, typically using the Autism Diagnostic Observation Schedule-2 (ADOS-2) and/or Monteiro Interview Guidelines for Diagnosing the Autism Spectrum, Second Edition (MIGDAS-2)
If required, cognitive and/or language assessment may also form a part of the assessment.
In the two weeks before the appointment, the information you’ve provided is carefully reviewed. On the day, your child attends a morning session, followed by time for the team to discuss observations. Parents then meet with the team via telehealth in the afternoon. Most families find it helpful to put aside the whole day (usually a Tuesday) for the assessment.
Much of the information collection is completed prior to your appointment with the assessors. As such, we are able to provide you with feedback within a few days of the assessment appointment. Sometimes, we may be waiting on additional information from other sources (e.g., a teacher questionnaire or therapy report) or need to conduct a daycare/school observation, and this can delay the feedback for a few days.
We can do feedback sessions via phone, or telehealth (e.g., Zoom, Microsoft Teams) at a time that is convenient to you.
We aim to provide full diagnostic reports to families and the referring medical specialist within 10-15 business days of the final assessment appointment. We are able to provide a letter confirming the outcome prior if this is required for school or to commence NDIS applications.
Children aged 3 and under with a pediatrician/psychiatrist referral- $2660
Should cognitive and/or formal language assessment or a school visit be required the additional fees added will be charged at a rate of $190 per hour.
Should an additional parent interview for separate parents be required, this will be charged at $500 (including report writing).
A $400 non-refundable deposit is required to secure your booking and the remaining fees are due on the day of the appointment and can be paid via EFT (HICAPS available), credit card, or via bank transfer. Please note paying via credit card will incur a 1% fee.
The assessment fees include the direct assessment with the child, a parent interview, administration of questionnaires, a full diagnostic report, review of all reports and consultations with your child’s paediatrician/psychiatrist, teacher/s and any therapists they may be seeing/have seen.
Children who have not been seen by a paediatrician or psychiatrist will also be screened and/or assessed for other developmental concerns such as global developmental delay, developmental language disorder and ADHD. This extra requirement accounts for the additional cost.
Cognitive (i.e. IQ) and/or language assessment may be required as part of your child’s assessment. The need for this will be discussed with you and is dependent on what services your child has already accessed and your specific concerns. If these assessments are required, there will be additional fees.
There are a few options that may reduce the out-of-pocket costs for families. These include:
We encourage you to consider the best funding source for your family and inform staff at AAP about any rebates you may be eligible for so we can ensure receipts reflect the funding you would like to use.
