For families and individuals across the UK, pursuing a diagnosis for Autism Spectrum Condition (ASC) or Attention Deficit Hyperactivity Disorder (ADHD) can be both an empowering and overwhelming process. As NHS services continue to experience significant delays, many people are turning to private diagnostic providers. However, the quality of assessments can vary widely.
At Clinic Autism, we are committed to delivering rigorous, ethical, and evidence-based neurodevelopmental assessments that are fully compliant with UK standards and tailored to the needs of each individual.
Why Is Diagnostic Quality So Important?
A high-quality diagnosis can open doors to essential support in education, employment, and healthcare. For children, it can enable access to an Education, Health and Care Plan (EHCP) and specialised support at school. For adults, it can provide legal protection under the Equality Act 2010 and eligibility for workplace adjustments and therapeutic services.
An assessment that lacks clinical depth or fails to meet national guidelines, however, may not be accepted by local authorities, schools, or NHS practitioners. It is therefore crucial to understand what sets a robust, professional diagnostic service apart.
Essential Features of a High-Quality Autism & ADHD Assessment
1. Conducted by a Multidisciplinary Team (MDT)
The National Institute for Health and Care Excellence (NICE) recommends that ASC and ADHD assessments be carried out by a multidisciplinary team. At Clinic Autism, our MDT includes:
Clinical and Educational Psychologists
Speech and Language Therapists (SLTs)
Occupational Therapists (OTs)
Psychiatrists
Paediatricians
This collaborative approach ensures that each assessment considers communication, sensory processing, attention, learning style, and mental health.
2. Use of Gold-Standard Assessment Tools
Clinic Autism uses a range of internationally recognised diagnostic tools, including:
ADOS-2 (Autism Diagnostic Observation Schedule, Second Edition)
3Di-5 (Developmental, Dimensional and Diagnostic Interview)
ADI-R (Autism Diagnostic Interview – Revised)
DIVA-5 (for adult ADHD diagnosis)
Conners 4 and QbCheck (for assessing ADHD traits in children and adolescents)
Sensory and functional assessments conducted by our OT team
These tools are administered in line with UK and international best practice, ensuring the diagnosis is evidence-based and suitable for formal use.
3. UK-Relevant Terminology and Clinical Reporting
While diagnostic manuals such as DSM-5 and ICD-11 still use the term "Autism Spectrum Disorder," there is a strong movement within the UK to adopt the more affirming term "Autism Spectrum Condition (ASC)." Clinic Autism uses inclusive, neurodiversity-informed language in all communications and reports.
Our diagnostic reports:
Clearly reference DSM-5 and/or ICD-11 criteria as required
Use ASC/ADHD language where appropriate
Include detailed recommendations for education, health, and daily functioning
Are accepted by NHS GPs, local authorities, schools, and workplaces
4. Ethical, Transparent, and Person-Centred Process
Every step of the assessment process at Clinic Autism is:
Compliant with NICE guidance
Delivered by clinicians registered with UK professional bodies (e.g., HCPC, GMC, BPS, BACP)
Transparent in cost, process, and timeframes
Adapted to the age, communication style, and needs of the individual
We do not take a "one-size-fits-all" approach. Whether you are a parent, carer, or adult seeking assessment, we aim to provide clarity, support, and respect throughout the diagnostic journey.
5. Post-Diagnostic Support
We recognise that a diagnosis is not the end point. High-quality assessments must be followed by meaningful support. Clinic Autism offers:
Comprehensive feedback sessions
Written recommendations tailored for use in EHCP applications, SEN planning, and Access to Work
Liaison with schools, employers, and other professionals
Signposting to trusted therapeutic, educational, and community services
Private vs NHS Assessments: What’s the Difference?
Feature | NHS Assessment | Clinic Autism (Private) |
Waiting Time | 18–36 months | 4–6 weeks |
Access to MDT | Variable | Full team including OT & SLT |
Diagnostic Tools | May vary | Always uses ADOS-2, 3Di-5 |
Report Recognition | Accepted | Accepted by UK institutions |
Post-Diagnostic Support | Limited | Included and person-centred |
While NHS pathways are invaluable, the current system often cannot meet the urgency of need. Private assessments can offer timely, thorough alternatives when conducted by a reputable, ethical service.
