Autism Assessments
for Adults and Children

Autism looks different in every person it touches, whether that's a child, an adult or a whole family navigating life together. It quietly shapes how we build relationships, express ourselves, process the world and manage the demands of daily living. For some, social settings can feel bewildering or draining, leaving little energy for anything else. Sensory experiences, whether it's noise, light, texture or crowded spaces, can tip quickly from manageable to overwhelming. Routine often becomes a source of real comfort and safety, while sudden change can bring genuine distress rather than mere inconvenience.

Seeking an autism assessment is rarely a simple administrative step. It can be the beginning of real understanding, both for the individual and for those around them. It offers language for experiences that may have felt confusing or isolating for years, and it can reveal strengths, talents and ways of thinking that had been overshadowed by struggle. Many families tell us the process brings not just answers, but relief.

With the right understanding, compassionate guidance and appropriate support in place, individuals and families can move from uncertainty toward genuine clarity. Diagnosis is not an endpoint but a foundation, one that allows you, your child or your loved one to feel truly seen, and to build a life shaped around their strengths rather than their struggles.

What to expect from your autism assessment

What is an autism assessment?

An autism assessment is an opportunity to better understand how you experience and interact with the world. It is a supportive process designed to explore your unique strengths, communication style, social experiences, sensory preferences, and patterns of thinking and behaviour. Many adults seek an assessment after recognising autistic traits in themselves, following a recommendation from a healthcare professional, or after a family member has been diagnosed. For some, an assessment can provide clarity and validation for experiences they have had throughout their life.The aim of the assessment is not simply to determine whether you meet the criteria for Autism Spectrum Disorder (ASD), but to develop a fuller understanding of your individual profile, identify strengths and challenges, and provide personalised recommendations that may support your wellbeing.

What is included in an adult's autism assessment?

Clinical interview (45 minutes)
Developmental history interview (60 minutes)
ADOS assessment (60 minutes)
Psychiatric evaluation (60 minutes)
Multidisciplinary team meeting
Feedback Session (30 minutes)

Understanding your assessment, Who will carry out the assessment?

Your assessment will be completed by a multidisciplinary team of professionals with expertise in autism and neurodevelopmental conditions.Following current clinical guidelines, the assessment brings together information from several sources to ensure a thorough and balanced understanding of your experiences. Depending on the assessment pathway, this may include psychologists, psychiatrists, psychotherapists, speech and language therapists, occupational therapists, and assistant psychologists. Each professional contributes their specialist knowledge to ensure that the assessment considers all relevant aspects of your development, communication, behaviour, sensory experiences, and mental health.

What is the client interview and why is it important?

The client interview is often the first appointment in the assessment process. This meeting allows the clinician to learn about your reasons for seeking an assessment, your current experiences, and any concerns or questions you may have. The interview also helps the clinician understand your communication style, social experiences, sensory preferences, daily functioning, and mental health history. Many people feel nervous before an autism assessment. This appointment provides an opportunity to build rapport with the clinician and create a supportive environment before the formal assessment process begins.

What is developmental history taking?

Understanding early development is an important part of any autism assessment. Autism is a lifelong neurodevelopmental condition, so clinicians seek information about childhood experiences as well as current functioning. The developmental history interview explores areas such as: Early social development, Communication and language development, Friendships and relationships, Interests and hobbies, Sensory experiences, Repetitive behaviours and routines and Educational experiences.

For adult assessments, there are several ways this information can be gathered. If a parent, caregiver, sibling, or another family member who knew you well during childhood is available, they may complete the developmental history interview on your behalf.

However, we recognise that this is not always possible. If no suitable informant is available, you may complete the developmental history interview yourself. Adults are often able to provide valuable insight into their childhood experiences, and clinicians will also consider information from educational records, previous reports, and other relevant sources where available.

What is an ADOS-2 assessment?

The ADOS-2 (Autism Diagnostic Observation Schedule, Second Edition) is considered one of the most widely used autism assessment tools internationally. The ADOS-2 involves a series of structured conversations and activities designed to help clinicians observe social communication, interaction style, imagination, and behavioural patterns.

For adults, the assessment feels more like a guided conversation than a test. There are no right or wrong answers, and the purpose is simply to understand how you naturally communicate and interact. The ADOS-2 is only one part of the assessment process and is always considered alongside developmental history, clinical interviews, questionnaires, and professional judgement.

Why does the assessment include a psychiatric evaluation?

Many autistic adults experience other conditions alongside autism, such as ADHD, anxiety, depression, obsessive-compulsive difficulties, eating disorders, or sleep difficulties. The psychiatric evaluation helps provide a broader understanding of your mental health and wellbeing. It also assists in identifying any co-occurring conditions that may require additional support or treatment. This holistic approach helps ensure that recommendations are tailored to your individual circumstances and needs.

What is a multidisciplinary team meeting?

Once all assessment information has been gathered, the clinicians involved meet to review the findings together. This multidisciplinary discussion allows different professional perspectives to be considered before reaching diagnostic conclusions. By combining information from interviews, observations, questionnaires, developmental history, and psychiatric evaluation, the team can develop a comprehensive understanding of your profile.This collaborative approach helps ensure that conclusions and recommendations are robust, balanced, and individualised.

What will be included in my written report?

Your assessment report will provide a detailed summary of the information gathered throughout the assessment process. The report typically includes background and developmental history, clinical interview findings, ADOS-2 observations, and psychiatric evaluation findings. It will also provide diagnostic conclusions, consideration of co-occurring conditions such as ADHD or anxiety where applicable, and individualised recommendations.The report is designed to provide a clear and compassionate understanding of your experiences and can be shared with healthcare professionals, educational providers, or employers if you choose to do so.

What can I expect from my feedback appointment?

The feedback appointment is the final stage of the assessment process. During this meeting, the clinician will explain the assessment findings, discuss whether you meet diagnostic criteria for Autism Spectrum Disorder, and answer any questions you may have. The clinician will also talk through any recommendations, discuss potential next steps, and provide guidance on available support and resources.Many people find this appointment helpful in making sense of their experiences and understanding how the assessment findings relate to their everyday life. Our aim is for you to leave the process with greater clarity, a deeper understanding of yourself, and practical guidance to support your future wellbeing.

What is an autism assessment?

They are not a requirement following your assessment, and you are free to decide whether, when, and with whom you take them forward. Some people choose to begin follow-up support straight away, while others prefer to take time to process their report first, or to explore support through other services, including the NHS or community organisations.
