Autism Assessments for Children, Young People and Adults

At Joanne Wright Psychology, we provide comprehensive, compassionate and neurodiversity-affirming autism assessments for children, young people and adults. The assessment process explores communication, social interaction, sensory experiences, routines, interests, emotional wellbeing and everyday functioning, while also recognising each person’s individual strengths and identity.

Seeking an autism assessment can bring a mixture of uncertainty, relief and important questions. Our aim is to make every stage clear, respectful and supportive, from the initial enquiry and information gathering through to diagnostic feedback, the written report and practical post-diagnostic recommendations.

What is an autism assessment?

An autism assessment is a detailed clinical evaluation used to determine whether a person’s experiences and developmental history are consistent with autism.

Autism is a lifelong neurodevelopmental difference. It can influence how a person communicates, relates to other people, processes sensory information, manages uncertainty and experiences the world around them.

Autism does not look the same in every person. Some autistic people have obvious support needs from early childhood, while others develop ways to compensate, mask or imitate expected social behaviour and are not recognised until adolescence or adulthood.

A comprehensive autism assessment considers the whole person rather than relying on a single questionnaire, observation or appointment. NICE guidance recommends gathering information about developmental history, current presentation, functioning in different settings and possible coexisting or alternative conditions.

Who may benefit from an autism assessment?

An autism assessment may be appropriate for:

children with differences in communication, play, sensory processing or social interaction;
young people who find friendships, school demands, change or emotional regulation difficult;
adults who have always felt different or found social expectations confusing or exhausting;
people who rely heavily on routines or become distressed by uncertainty;
individuals who experience significant sensory sensitivities;
girls and women whose autistic characteristics may have been overlooked;
people who mask their difficulties in public but experience exhaustion or distress afterwards;
parents seeking a clearer understanding of their child’s strengths and support needs;
individuals who have previously received diagnoses such as anxiety, depression or ADHD but feel that autism may also be relevant.

You do not need to be certain that you or your child are autistic before making an enquiry. The purpose of the assessment is to explore this possibility carefully and objectively.

Common reasons people seek an autism assessment

People may seek an assessment because they experience:

difficulty understanding social expectations or unwritten rules;
uncertainty about how to begin or maintain conversations;
feeling misunderstood by other people;
difficulty developing or maintaining friendships;
a need for predictability and routine;
distress when plans change unexpectedly;
intense or highly focused interests;
repetitive movements, actions or ways of regulating;
heightened or reduced sensitivity to sound, light, touch, smell, taste or movement;
emotional overwhelm, shutdowns or meltdowns;
difficulty identifying or expressing emotions;
exhaustion following social interaction;
masking or copying others to fit in;
anxiety linked to school, work, relationships or unfamiliar situations;
a longstanding sense of being different without understanding why.

Individual characteristics can have many possible explanations. An assessment considers whether autism provides the most appropriate overall explanation and whether other needs should also be explored.

The Autism Assessment Process

1. Initial enquiry

The process begins when you contact Joanne Wright Psychology to ask about an autism assessment.

You will receive information about:

who the assessment is for;
the stages involved;
appointment arrangements;
the likely timescale;
assessment fees;
the information and documents required;
opportunities to ask questions before proceeding.

This initial contact helps determine whether an autism assessment appears appropriate and whether any adjustments may be needed.

2. Pre-assessment questionnaires and information gathering

Before the main appointments, questionnaires may be completed by the person being assessed and, where appropriate, by parents, carers, teachers or another person who knows them well.

For a child or young person, information may be requested from:

parents or carers;
the school, college or nursery;
the SENCO or class teacher;
other professionals involved in the child’s care;
previous educational, psychological or clinical reports.

For an adult assessment, information from a parent, sibling, partner or another person who has known the individual for a long time can be helpful. However, the assessment can still be considered when childhood records or family informants are unavailable.

Questionnaires support the assessment but do not provide a diagnosis on their own.

3. Developmental history interview

A detailed developmental history is an important part of the autism assessment.

For children, this will usually involve a parent or carer. For adults, Joanne may speak with the individual and, where possible and agreed, someone who knew them during childhood.

The discussion may cover:

pregnancy, birth and early development;
early communication and language;
play and imagination;
friendships and social interaction;
interests and preferred activities;
routines and response to change;
sensory experiences;
behaviour and emotional regulation;
experiences at school;
family life and relationships;
independence and daily living skills;
current strengths and support needs.

Autism is developmental, so the assessment considers both current experiences and whether relevant differences were present from an early age, even if they were not recognised at the time.

4. Clinical interview with the person being assessed

The individual will have an opportunity to describe their own experiences, concerns and reasons for seeking an assessment.

Depending on their age and communication preferences, the appointment may explore:

social communication;
friendships and relationships;
sensory needs;
interests;
routines;
experiences of change;
emotional wellbeing;
education or employment;
masking and coping strategies;
areas of strength;
what support would be most helpful.

The appointment should feel collaborative rather than like a test. Clear explanations, breaks and communication adjustments can be provided where needed.

5. Autism-focused observation or assessment activity

The assessment may include a structured, autism-focused observation or interaction.

This is used to understand aspects of:

verbal and non-verbal communication;
reciprocal conversation and interaction;
social understanding;
imagination or flexible thinking;
interests and patterns of behaviour;
how the person approaches the assessment situation.

No single observation can confirm or rule out autism. Some people may mask strongly during appointments or present differently in unfamiliar environments. The findings must therefore be considered alongside developmental history, questionnaires and information from everyday settings.

6. Information from home, education or work

Autistic characteristics may be expressed differently in different environments.

A child might appear quiet and compliant at school but experience distress, exhaustion or meltdowns at home. An adult may perform well professionally while finding social interaction, sensory demands and organisation extremely draining.

The assessment therefore considers functioning across settings such as:

home;
school or college;
employment;
friendships and relationships;
community activities;
independent living.

NICE advises that parents’ and carers’ concerns should be taken seriously even where those concerns are not shared by other people or settings.

7. Consideration of masking

Masking involves consciously or unconsciously hiding autistic characteristics or adopting behaviours that help a person appear to fit social expectations.

Examples may include:

rehearsing conversations;
copying facial expressions or gestures;
forcing eye contact;
suppressing movements used for regulation;
imitating friends or colleagues;
carefully studying social rules;
appearing composed while experiencing significant internal distress.

Masking can make autism more difficult to recognise, particularly in girls, women, academically able individuals and people diagnosed later in life.

A thorough assessment considers the effort required to cope, not simply how the person appears during one appointment.

8. Consideration of other possible explanations and coexisting needs

The assessment also explores whether the person’s experiences may be explained or influenced by other developmental, psychological, educational or medical factors.

These may include:

ADHD;
anxiety or depression;
trauma;
speech and language differences;
learning disabilities or specific learning difficulties;
sensory-processing differences;
obsessive-compulsive difficulties;
attachment and early-life experiences;
intellectual disability;
physical-health conditions;
sleep difficulties.

Autism can coexist with other conditions, including ADHD. A previous ADHD diagnosis should not automatically prevent or delay consideration of an autism assessment.

9. Clinical review and diagnostic decision

Once the appointments and information gathering have been completed, Joanne and the assessment team review all the available evidence.

This may include:

developmental history;
clinical interviews;
autism-focused observations;
questionnaires;
school or workplace information;
previous professional reports;
evidence of strengths and support needs;
the effect on everyday functioning;
possible coexisting or alternative conditions.

The diagnostic decision is based on the overall pattern of evidence rather than any single score.

Possible outcomes include:

the evidence supports an autism diagnosis;
the evidence does not support an autism diagnosis;
further information or assessment is needed before a conclusion can be reached.

The reasons for the conclusion will be explained clearly and sensitively.

10. Feedback appointment

Following the assessment, a feedback appointment will be arranged.

This provides an opportunity to discuss:

the findings;
whether the diagnostic criteria have been met;
the person’s individual profile;
recognised strengths;
areas where support may be helpful;
possible coexisting needs;
recommendations and next steps.

Questions are welcomed, and information will be explained in clear, accessible language. NICE guidance emphasises involving people in decisions about their care and ensuring that explanations are understandable.

11. Written autism assessment report

A detailed written report will normally be provided after the assessment.

The report may include:

the reason for referral;
developmental and background information;
the assessment methods used;
a summary of the evidence;
the diagnostic conclusion;
the person’s strengths and needs;
recommendations for home, education or work;
suggested reasonable adjustments;
guidance about post-diagnostic support.

With appropriate consent, the report can be shared with schools, universities, employers, healthcare professionals or other relevant services.

Autism Assessments for Children

A child autism assessment considers the child’s development, communication, play, relationships, sensory needs, behaviour and emotional regulation.

Children may show autistic characteristics in different ways. Some may have clear communication or developmental differences, while others may appear socially confident but struggle to understand friendships, manage uncertainty or cope with sensory demands.

Possible signs may include:

differences in eye contact, gestures or facial expression;
difficulty with reciprocal conversation or play;
highly focused interests;
repetitive play or movement;
distress around change;
sensory sensitivities;
literal interpretation of language;
difficulty understanding social situations;
shutdowns, meltdowns or emotional overwhelm;
appearing to cope in school but becoming distressed at home.

The assessment is not intended to judge the child’s behaviour. Its purpose is to understand how the child experiences the world and what support may help them feel safe, included and able to thrive.

Recommendations may include:

predictable routines;
visual information;
sensory adjustments;
support with transitions;
clearer communication;
emotional-regulation strategies;
reasonable adjustments in school;
support with friendships and social understanding;
reduced demands during periods of overwhelm;
staff awareness and training.

The role of parents and schools

Parents and carers bring essential information about development, behaviour, communication and everyday life.

Schools and education settings can also provide valuable evidence about:

learning and participation;
communication with adults and peers;
sensory responses;
behaviour during transitions;
social interaction;
emotional regulation;
support already being provided.

Differences between home and school are common and will be explored carefully. A child’s ability to remain quiet or compliant in school does not necessarily mean they are coping comfortably.

Autism Assessments for Adults

Many adults seek an autism assessment after years of feeling different, misunderstood or exhausted by social expectations.

Some recognise autistic characteristics after:

their child is diagnosed;
experiencing workplace burnout;
struggling with relationships;
receiving treatment for anxiety or depression;
learning more about masking;
finding that everyday demands have become harder to manage.

Adults may describe:

rehearsing conversations;
difficulty interpreting other people’s intentions;
feeling socially disconnected;
becoming exhausted after interacting with others;
sensory overwhelm;
a strong need for routines;
distress when plans change;
intense interests;
difficulty identifying emotions;
consciously copying other people to fit in;
needing significant recovery time after work or social events.

A later-life diagnosis can provide an explanation for longstanding experiences and help the person develop a more compassionate understanding of themselves.

Autism Assessments for Girls and Women

Autistic girls and women may be overlooked because their characteristics do not always match traditional stereotypes of autism.

They may:

imitate peers successfully;
have interests that appear socially typical but are unusually intense;
force themselves to make eye contact;
appear quiet, shy or highly compliant;
prepare scripts for conversations;
experience perfectionism or high anxiety;
maintain friendships through considerable effort;
release accumulated distress at home;
receive earlier diagnoses of anxiety, depression or eating difficulties.

The assessment considers both outward behaviour and the internal effort required to manage social, sensory and emotional demands.

What happens after an autism diagnosis?

An autism diagnosis may bring relief, validation, sadness, uncertainty or a combination of emotions. There is no correct way to respond.

Following diagnosis, support may include:

post-diagnostic consultations;
learning more about autism and personal identity;
understanding sensory and communication needs;
identifying reasonable adjustments;
support for parents or partners;
psychological therapy adapted for autistic people;
school or workplace recommendations;
SEND and EHCP guidance;
signposting to relevant services;
developing strategies for emotional regulation and preventing burnout.

Autism is not an illness that needs to be cured. The focus should be on understanding the individual, reducing unnecessary barriers and providing appropriate support.

A Neurodiversity-Affirming Assessment

At Joanne Wright Psychology, autism assessment is approached with respect for neurodiversity.

The process does not focus solely on deficits. It recognises that autistic people may also have significant strengths, including:

honesty and integrity;
strong attention to detail;
creativity;
specialist knowledge;
loyalty;
persistence;
logical or analytical thinking;
original problem-solving;
a strong sense of fairness;
deep commitment to areas of interest.

The aim of assessment is not to change who someone is. It is to promote understanding, identify helpful support and reduce the pressure to function in environments that do not meet their needs.

Frequently Asked Questions About Autism Assessments

How long does an autism assessment take?

The assessment process normally involves several stages, including questionnaires, developmental history, clinical interviews or observations, review of supporting information, a feedback appointment and preparation of the written report. The overall timescale depends on the individual and the evidence available.

Can adults have an autism assessment?

Yes. Many autistic people are not identified during childhood. An adult autism assessment considers present-day experiences alongside developmental history and evidence that relevant characteristics were present from an early age.

Do I need a GP referral for a private autism assessment?

A GP referral is not usually required to enquire about a private assessment, although relevant medical or psychological information may be requested. You should check any specific requirements if an insurer or another organisation is funding the assessment.

Can autism be diagnosed through a questionnaire?

No. Questionnaires can help gather information and identify characteristics that require further exploration, but they cannot provide a diagnosis on their own.

What assessment tools are used?

The precise assessment methods depend on the person’s age, communication profile and circumstances. They may include developmental interviews, clinical interviews, structured observations, questionnaires and information from parents, schools or other people who know the individual well.

Will my child’s school need to be involved?

Information from school is usually valuable because autism is assessed across different environments. The school may be asked to complete a questionnaire or provide information about communication, learning, sensory needs, social interaction and emotional regulation.

What happens if school does not share our concerns?

Children can behave very differently at home and school. Some children mask or use considerable effort to cope in education. Differences between accounts will be explored rather than automatically treating one setting as more reliable.

What if I cannot provide childhood information for an adult assessment?

Childhood information is helpful because autism is developmental, but many adults cannot access school reports or speak with a parent. Joanne will discuss what alternative evidence may be available and whether a reliable diagnostic conclusion can be reached.

Can someone have both autism and ADHD?

Yes. Autism and ADHD can occur together. The assessment will consider whether attention, impulsivity, activity levels or executive-function difficulties indicate additional ADHD needs.

Can girls and women be autistic?

Yes. Girls and women may be under-recognised because they can present differently, mask more extensively or have interests that do not match traditional assumptions about autism.

Does making eye contact mean someone cannot be autistic?

No. Some autistic people can make eye contact, particularly when they have learned to do so deliberately. The assessment considers the comfort, effort and meaning of communication rather than relying on one behaviour.

Can an autistic person have good friendships or relationships?

Yes. Autistic people can develop close friendships, partnerships and family relationships. Autism affects people differently, and having relationships does not rule out a diagnosis.

Will I receive a written report?

Yes. A written report will normally explain the assessment process, evidence considered, clinical conclusion, strengths, identified needs and practical recommendations.

Will an autism diagnosis help with school support or an EHCP?

An assessment report can provide useful evidence about a child’s needs and recommended provision. However, a diagnosis does not automatically result in an EHCP. Decisions are based on the child’s special educational needs and the support required.

Can an assessment be completed online?

Some parts of an autism assessment may be completed online where clinically appropriate. The format will depend on the person’s age, needs, communication profile and the assessment methods required.

Is the assessment confidential?

Yes. Personal information is handled confidentially and in accordance with professional and data-protection requirements. Information is shared only with appropriate consent, except where there is a legal or safeguarding duty to act.

What happens if the assessment does not result in a diagnosis?

The feedback and report will explain why the evidence did not support an autism diagnosis. Where possible, Joanne will identify other relevant needs, suggest alternative explanations and recommend appropriate next steps or support.

What is post-diagnostic support?

Post-diagnostic support helps individuals and families understand the diagnosis, identify personal strengths and needs, consider reasonable adjustments and develop practical strategies for home, education, work and relationships.

How do I arrange an autism assessment?

Contact Joanne Wright Psychology with a brief explanation of who the assessment is for and the main reasons for seeking support. You will then receive information about availability, fees, assessment stages and the next steps.
