Autism diagnostic assessment process

Autism diagnostic assessment process

What to do if you think your child might be autistic

Receiving support at the earliest stage without the need for a diagnosis is really important to help you and your child. If you think your child may be autistic, talk to a health, education or social care professional. They can help you consider if your child might be showing signs of autism. 

These are different from one person to another but may include any of the following:

  • difficulties with social communication
  • difficulties with social interaction
  • restrictive and repetitive behaviours
  • repetitive activities and interests since early childhood
  • disturbance of daily functions due to the above
  • other difficulties such as sensory processing and co-ordination difficulties
  • difficulties in learning, information processing and other behaviours may be apparent

The professional should work with you to think about and put in place adjustments or strategies to help meet the needs of your child. These are made as part of a graduated response of support and are a combination of academic adjustments made in an education setting and strategies to try at home to help daily life. It may also involve small adjustments made to usual school processes that make the child’s life easier, or onward referral to services that provide support. 

What this looks like is different for every young person. 

Help for you

Being a parent carer of a child or young person with additional needs can bring extra situations which are challenging to know how to handle. It can also be frustrating while you are waiting for your appointment, not knowing where to turn next. There are however a number of online resources, workshops and parent support groups that you can access while you are waiting. To help support parent and carers the resources and parenting workshops cover subjects other parents have found useful. You don’t have to wait to have a diagnosis to access these workshops for parents and carers.

Starting Well offer some specific groups and workshops, all of these are free:

offers free online autism and anxiety training for parents carers of children who have been accepted for assessment on the Autism diagnostic pathway or who have received a diagnosis of autism. 

offer 1 to 1 support, on-line workshops and podcast on useful topics.

How a child or young person is referred for a diagnostic assessment

´óÐãÊÓƵ Community Paediatric Service undertake Autism assessment and diagnosis for children age 0 to 17 years and 6 months, this pathway is also known as the ´óÐãÊÓƵ Umbrella Pathway. A referral can be made for an assessment by a GP (doctor), school or school nurse. A referral should be made only once reasonable steps have already been made to support the young person and family in line with the Graduated Response for Neurodivergent Children and Young People. For practical purposes, referrals for those over 16 will be considered in terms of whether assessment by an adult service may be more appropriate. 

It is not unusual for children to present differently at home and at nursery or school. To understand this the assessment team requires some detailed information to begin the process. The information provided forms part of the child or young person’s assessment if they are accepted for the assessment pathway. The information consists of the following 4 parts and all of these need to be completed in full before the referral can be considered:

  1. a referral form  
  2. an age-appropriate consent form (young people aged 16 and over only)
  3. questionnaire completed by parent or carer
  4. questionnaire completed by educational setting (as long as the child or young person is attending one)

Where a child or young person does not attend an education setting, it is useful but not essential, to get a report from another setting the child goes to such as an activity or sports club. This helps the assessment team to understand how the child or young person presents in different situations.

What happens next

The information provided will be assessed by a member of the assessment team. The assessment team consists of: Community Paediatricians, Speech and Language Therapists, Occupational Therapists and Clinical Psychologists. 

A decision will be made to either:

  1. continue to a diagnostic assessment. An appointment will be sent to you for an assessment
  2. ask for further information. Sometimes this happens if the information supplied by home or school is not detailed enough, in which case the team will ask for additional information
  3. decline a referral if the information doesn’t show a need for further assessment. In this case, the assessment team will suggest referral to other services that would better meet your child’s needs

Initial appointment 

Once accepted, an initial appointment will be held with you and your child and the clinician will decide if any further assessments are needed to help understand your child’s needs better. If needed, further assessments would be carried out by the appropriate professionals and tailored to the individual needs of your child. 

These could include:

  • a neurodevelopmental history
  • Clinical Psychologist assessment 
  • specialist speech and language assessment
  • observations in education settings

A follow up appointment with a professional not previously involved may also be recommended.

In some circumstances, a specific evidence based assessment for Autism such as ADOS will be recommended by the team.

The diagnostic discussion 

A minimum of 2 clinician from the assessment team will evaluate the evidence collected and a diagnosis of Autism will be considered. The final decision will always include a Senior Clinician. A diagnosis of autism may or may not be given.

Feedback appointment

An assessment report will be produced detailing your child’s strengths, areas of challenge and strategies to support daily life (home or education). Sign-posting information will also be provided.

A face-to-face appointment will be held with the child, young person and their family to go through the feedback and the assessment report. 

Waiting times

The assessment team understands that everyone wishes to be seen as soon as possible and it can be difficult to wait for appointment without an idea of timescale. Due to extremely high demands on the service, it is currently difficult to outline exact waiting times for your child’s initial appointment. Please be reassured that your child will be offered an appointment as soon as one becomes available. NHS Herefordshire and ´óÐãÊÓƵ are working with the team to bring down waiting times and provide useful information while you wait. 

Choosing a different provider

In England under the NHS you now have a legal right to choose a different provider of Autism or Attention Deficit Hyperactivity Disorder (ADHD) assessments, this is called Patient Choice and sometimes Right to Choose. This means that, should you decide the waiting time for your assessment is too long, then you can choose to leave the NHS waiting list and go to an alternative provider. The provider must supply the service to the NHS somewhere in England. Your GP can advise you on which providers are able to offer Patient Choice assessments and refer you. NHS Herefordshire and ´óÐãÊÓƵ are developing a list of quality-assured Patient Choice providers. The link to this list will be added shortly. In the meantime, some of the providers of Right to Choose Assessments for autism and ADHD can be found here: .

Statement on steps to improve support and diagnostic assessment process for Paediatric Autism and Attention Deficit Hyperactivity Disorder (ADHD)

Over recent years there has been a dramatic increase in referrals for paediatric diagnostic assessments for ADHD and Autism with referrals for assessment growing by over 300% from the pre-pandemic levels. Demand for local services currently exceeds capacity and steps are being taken to address this. NHS Herefordshire and ´óÐãÊÓƵ is working closely with:

  • local providers to reduce the waiting times and 
  • with partners organisations, children, young people and families to re-design the care pathways for Autism and ADHD, bringing them into one Paediatric Neurodevelopmental Care Pathway linked to mental health support

In the meantime, we know families need support while they are waiting for and following a diagnostic assessment. So, we are also improving information available on Autism and ADHD here through the Council’s ‘Local Offer’ website and while people wait from an appointment.
