Will Barker’s Statement on Private Autism & ADHD Assessments
In recent years, some UK media outlets have raised concerns about the quality and reliability of private autism and ADHD assessments. These narratives often suggest that private clinicians diagnose too readily, or that assessments outside the NHS lack rigour. While these stories can understandably create worry for families seeking timely support, they rarely reflect the reality of high‑quality independent practice.
At Will Barker Assessments, we want to be absolutely clear: our assessments are thorough, evidence‑based, and fully compliant with NICE guidelines. We follow the same clinical standards, use the same gold‑standard tools, and uphold the same professional responsibilities as NHS services. The difference is not in the quality of assessment—it is in the accessibility and timeliness of care.
Our Commitment to NICE‑Compliant Practice
Every assessment we deliver adheres strictly to the National Institute for Health and Care Excellence (NICE) guidance for autism and ADHD. This includes:
-
Use of validated, gold‑standard diagnostic tools such as ADOS‑2, ADI‑R, and 3Di
-
A multidisciplinary approach, incorporating developmental history, behavioural observation, and collateral information
-
Consideration of co‑occurring conditions, including mental health, physical health, and sensory needs
-
Holistic formulation, not just symptom checklists
-
Clear, evidence‑based recommendations for support, intervention, and onward referral
NICE compliance is not optional—it is foundational to safe, ethical, and accurate neurodevelopmental assessment. We are proud to uphold these standards in every case.
Dispelling Misconceptions About Private Assessment
Private assessment is sometimes portrayed as rushed or overly generous in diagnosis. In reality, high‑quality independent clinicians often have more time, more flexibility, and greater capacity to explore a young person’s needs in depth. Our assessments are:
-
Comprehensive, often lasting several hours across multiple sessions
-
Collaborative, involving parents, schools, and other professionals
-
Holistic, considering the whole child—not just diagnostic criteria
-
Transparent, with clear reasoning and evidence behind every conclusion
A diagnosis is never given lightly. It is given when the evidence is clear, consistent, and meets NICE‑defined thresholds.
Why Families Choose Independent Assessment
Many families turn to private assessment not because they want a shortcut, but because they want clarity, understanding, and support without years of waiting. Long NHS waiting lists can leave young people struggling without guidance, affecting their mental health, education, and family life. Private assessment offers a timely, ethical alternative that still meets the highest clinical standards.
Our Values: Integrity, Accuracy, and Young‑Person‑Centred Care
We believe neurodivergent young people deserve assessments that honour their individuality, strengths, and lived experience. Our work is grounded in:
-
Clinical integrity
-
Evidence‑based practice
-
Compassionate communication
-
Holistic understanding
-
Respect for neurodiversity
We do not diagnose to satisfy demand. We diagnose to provide clarity, support, and a pathway forward for young people who genuinely need it.
