Neurodevelopmental Assessments for Children and Adolescents Guide
Understanding Pathological Demand Avoidance (PDA)
A practical, neuroaffirming guide for parents and schools
Looking beyond "won't" to understand "can't, not yet, not safely, or not in this way."
Every child is unique
Children develop at different rates, and every child has their own pattern of strengths and vulnerabilities. Sometimes, however, parents, carers, educators or health professionals may notice that a child is finding certain areas of everyday life more difficult than expected. This may include learning, attention, emotional regulation, behaviour, social communication, independence, sensory processing, school participation or daily routines.
A psychological assessment can help explain why a child may be experiencing these challenges and identify the types of support that may help them thrive. Assessment is not about identifying what is "wrong" with a child. It is about understanding how they experience the world, where they may need support, and how the adults around them can respond more effectively.
A psychological assessment gives your child a voice, helping those around them truly understand how to provide the right support at the right time.
What is a psychological assessment?
A psychological assessment is a structured process used to better understand a child's developmental, cognitive, learning, behavioural, emotional, social and adaptive functioning. Assessment results are used to develop a clear profile of the child's strengths, challenges and support needs, which can then guide practical recommendations across home, school and therapy settings. It looks across:
Cognitive development: IQ testing, working memory, processing speed, fluid reasoning and crystallised reasoning, helping identify how a child learns best and informing targeted learning support and classroom strategies.
Attention and executive function: sustained attention, inhibition, cognitive flexibility, working memory, planning and organisation, often closely linked to ADHD.
Learning and achievement: standardised academic testing in reading, writing, spelling and mathematics, which can assist in identifying specific learning disorders such as dyslexia, dyscalculia or dysgraphia.
Language and communication: receptive language, expressive language and pragmatic or social communication skills, which can also contribute to autism assessment.
Emotional and behavioural functioning: anxiety, depression, trauma responses, emotional dysregulation, behavioural concerns and social difficulties.
Adaptive and daily living skills: self-care, community participation and functional independence, which may also be relevant to NDIS eligibility.

Why families seek assessment
Families may seek a psychological assessment for many different reasons. Sometimes there is a specific concern identified at school or by a health professional. Other times, parents have observed their child struggling with aspects of daily life and are looking for answers, clarity and practical guidance.
Common areas of concern include learning, reading, writing or mathematics; attention, concentration or task completion; emotional regulation, anxiety or distress; behavioural outbursts, shutdowns or meltdowns; social communication or peer relationships; transitions, routines or flexibility; sensory sensitivities or sensory seeking; daily living skills and independence; and school attendance or participation.
Assessment can also support clarifying existing or suspected diagnoses, documentation for school planning and adjustments, NDIS access or review processes, specialist medical referrals, broader therapeutic planning, uneven or unexpected developmental patterns, developmental delays across any domain, and supporting parent understanding and advocacy.
What to expect: the assessment process
Our assessment process is structured, transparent and tailored to each child, moving through intake, testing, feedback and report. The psychologist guides your family through every step, explaining what is happening and why, so nothing feels unexpected or confusing along the way.
Step one: intake and diagnostic interview
Before your child's first appointment, you will be asked to complete intake and consent forms. These help us understand your child's developmental history, current strengths, areas of concern and the reason for referral. The intake appointment, typically completed with the parent or guardian, allows the psychologist to gather detailed information about development, medical history, learning profile, behaviour, emotional wellbeing, social communication, daily living skills and current support needs, and helps determine which assessment tools are most appropriate.
Helpful documents to bring include previous psychological reports and learning support plans, paediatrician, psychiatrist or speech pathology letters, occupational therapy or behaviour support plans, school reports and teacher observations, NDIS plans or functional capacity reports, and medical or developmental history records.
Step two: testing and evaluation
The assessment process may include a combination of direct testing, clinical interview, behavioural observation, questionnaires and review of previous reports. Children do not need to study or practise before an assessment; the tasks are designed to evaluate how a child naturally approaches different types of information and problem-solving demands.
The psychologist will also carefully consider how your child presents during testing, including attention, persistence, confidence, emotional regulation, social engagement, sensory needs, fatigue and motivation. This observational information is just as valuable as the formal test scores.
Testing may include direct testing (answering questions, solving puzzles, structured cognitive and learning tasks), academic tasks (reading, spelling, writing and mathematics), social communication activities (play-based, conversation-based or structured observation), and questionnaires (standardised rating scales completed by parents, carers and teachers).
There is no pass or fail in a psychological assessment. The goal is simply to understand how your child learns, thinks and experiences the world.
Step three: feedback session and report
Once all assessment information has been gathered, scored and interpreted, parents or guardians attend a feedback session with the psychologist, who explains the results, diagnostic conclusions where relevant, and practical recommendations, with the chance to ask questions and discuss what the findings mean at home, school and in the broader community.
Following the feedback session, you will receive a comprehensive written psychological assessment report, which can be shared with schools, medical practitioners, allied health professionals, NDIS planners or other support providers at the family's discretion.
The feedback session covers your child's strengths and learning profile, cognitive and executive functioning findings, social communication and behavioural profile, adaptive behaviour and daily living results, diagnostic impressions where relevant, school, therapy and NDIS recommendations, and referrals to other professionals if required.
The written report may include the reason for referral and background history, assessment tools used and behavioural observations, detailed results and interpretation of findings, diagnostic conclusions if applicable, functional strengths and challenges, and recommendations for home, school, therapy and further medical or allied health review.
Preparing your child for assessment
The best preparation is to help your child arrive feeling rested, supported and ready to try their best. There is no need for your child to prepare or practise anything in advance. It can be reassuring to explain that they will take part in different activities designed to help us understand how their brain learns and solves problems, and that there is no expectation to be perfect.
Rest and nutrition: a good night's sleep and a proper meal help your child show what they can do more accurately. Pack a drink and a few snacks in case they're needed during the session.
Medication and health: talk with the psychologist ahead of time about your child's usual medication routine on assessment day, and let us know about any changes in medication, sleep or general health. If your child is unwell on the day, it is best to reschedule.
Assistive needs: bring any sensory aids, comfort items, communication devices or fidget tools your child uses regularly, along with glasses, hearing aids or other assistive technology.
After the appointment: assessment sessions can be tiring and emotionally demanding, even when they go well. Planning something low-key and enjoyable afterwards can help your child decompress. It is very normal for children to feel tired, quiet or emotional once the appointment is over.
Our approach
At Redefini Therapies, our assessment approach is child-centred, family-informed and neuroaffirming. We aim to understand the whole child, not just test scores or diagnostic labels, considering how a child functions across real-life environments including home, school and community settings.
Child-centred: every assessment is individually tailored, with tools selected based on the child's age, developmental profile, referral question and individual needs, and pace and environment adjusted to help the child feel comfortable throughout.
Family-informed: families are treated as the experts on their own child, with input actively sought at every stage, and observations from home, school and community valued just as highly as formal test results.
Neuroaffirming: assessment is not about finding deficits. It is about understanding how a child's brain works and identifying the supports that will help them thrive, with language in reports and feedback that is strengths-based, affirming and practical.
Transparent: the psychologist explains every step clearly and in plain language, and the feedback session is designed to be a genuine conversation, not just a delivery of results.
