How can parents request an evaluation for their child suspected of having autism? 

When parents begin to notice that their child is struggling with social communication, routines, or behaviour, it can be both worrying and confusing. Understanding how to request an autism assessment is an important first step. According to NHS and NICE guidance, parents in the UK can request an evaluation through their GP, their child’s school, or by using the NHS Right to Choose pathway. The goal of assessment is not just diagnosis, but to identify the support a child may need at home, school, and in daily life. 

Recognising when to seek an autism evaluation 

Early recognition makes a real difference. Signs of autism can appear in early childhood, but may become more noticeable once a child enters nursery or school. According to the NHS (2024), concerns might include differences in communication, social interaction, repetitive behaviours, or intense interests. Teachers, health visitors, or family members often share observations that can guide parents toward requesting an assessment. 

The NICE guidance (2023) recommends that professionals act promptly when autism is suspected. It advises that children showing signs of autism should be referred through structured local pathways, often coordinated by a specialist neurodevelopmental team. This ensures assessment and support begin as early as possible. 

How to request an autism assessment 

Parents can request an autism evaluation in three main ways: 

1. Through your GP or health visitor 

According to the NHS Right to Choose guidance (2025), parents in England have the legal right to request an NHS-funded autism assessment from any approved provider. This means families can choose between local NHS services or other qualified providers registered under the Right to Choose framework. Your GP can initiate this referral on your behalf. 

2. Through your child’s school 

Many schools now have procedures to identify and support children who may be neurodivergent. The Department for Education (2024) states that schools should work collaboratively with parents to raise concerns and record early observations through Special Educational Needs (SEN) processes. The school’s SENCO (Special Educational Needs Coordinator) can liaise directly with health professionals and local authorities to start a joint referral for assessment. 

3. Directly through local NHS pathways 

Some NHS Trusts, such as Newcastle Hospitals, allow parents to refer their child directly to autism diagnostic services. These referrals typically require a short written summary describing behaviours or developmental differences observed at home and school. Health visitors and teachers often contribute supporting information to strengthen the referral. 

The National Autistic Society (2024) recommends that parents prepare detailed notes of behaviours and social interactions, as well as examples of challenges or progress over time. Providing this evidence helps clinicians understand the full picture of your child’s development. 

What happens after you make a referral 

Once the referral is accepted, your child will usually be placed on a waiting list for a multidisciplinary assessment. This team may include paediatricians, psychologists, speech and language therapists, and occupational therapists. The WHO ICD-11 (2023) defines Autism Spectrum Disorder (6A02) as a neurodevelopmental condition requiring evaluation by qualified professionals who assess social communication, sensory behaviours, and developmental history. 

The assessment process often includes structured observation (such as ADOS-2), developmental questionnaires, and interviews with parents or caregivers. Some areas also include educational observations to see how the child interacts in different settings. 

According to Autistica (2024), delays between referral and diagnosis remain a major issue across the UK. Their research highlights long waiting times and inconsistent referral criteria between health and education systems. Autistica calls for stronger integration between schools and NHS pathways to improve early access to assessments and post-diagnostic support. 

The importance of parental input 

Parents play an essential role throughout the diagnostic process. A 2024 PubMed review found that early referrals are often driven by parent observations of speech, play, and social differences. Families who advocate early tend to access interventions sooner, which can improve developmental outcomes. NICE also advises professionals to listen closely to parental concerns, even when a child’s school performance seems typical, as autism may present differently in structured environments. 

The NAS further notes that every referral should recognise the family’s perspective, as parents often notice subtle patterns such as differences in eye contact, play preferences, or emotional responses that may not be visible in clinical settings. 

What to expect after diagnosis 

Following diagnosis, parents should receive written reports summarising findings, along with recommendations for school support, speech and language therapy, and emotional wellbeing. The NHS advises that a diagnosis can help families access tailored interventions, Education, Health and Care Plans (EHCPs), and appropriate learning accommodations. 

However, as Autistica (2024) and NICE (2023) emphasise, diagnosis itself does not automatically grant access to support. Instead, schools and local authorities use the information from the assessment to decide if a formal EHCP is required. Parents can then request this through their local council if their child’s needs go beyond what the school can provide through standard SEN support. 

Overcoming barriers to assessment 

Despite improvements, families still report challenges in obtaining timely assessments. According to NHS England data, demand for autism evaluations continues to rise, with waiting times exceeding a year in many areas. Autistica’s LeDeR Report 2025 found that improved communication between GPs, schools, and parents reduces delays and improves satisfaction with the process. 

Parents who face difficulties can contact their local SEND Information, Advice and Support Service (SENDIASS) for guidance, or seek help from charities like NAS. Many families also explore the NHS Right to Choose option to access approved assessment providers more quickly. 

Takeaway 

Parents are often the first to recognise when something feels different about their child’s communication or behaviour. You have the right to request an autism evaluation through your GP, school, or NHS Right to Choose provider. Early referral helps children access tailored education, support, and therapies that can make a lasting difference.
