The NICE guideline NG87 sets the standard for ADHD diagnosis and management across all ages in England and Wales. For commissioners responsible for designing or procuring ADHD services, understanding this pathway is essential. Without a clear grasp of each step, from referral through to ongoing monitoring, it becomes difficult to specify services, evaluate provider bids, or secure funding. This step by step guide explains the NICE ADHD diagnostic pathway for commissioners and highlights the workforce challenges that specialist recruitment can solve.
What is the NICE ADHD Diagnostic Pathway
The NICE ADHD diagnostic pathway, formally known as NG87, outlines the clinical steps required to identify, assess, and manage attention deficit hyperactivity disorder in children, young people, and adults. It was published by the National Institute for Health and Care Excellence and is the recognised standard in England and Wales. The pathway covers everything from initial recognition of symptoms to post-diagnostic support and ongoing monitoring.
Commissioners must align local services with NICE recommendations to secure NHS funding and meet regulatory expectations. Services that deviate from NG87 risk poor outcomes, increased complaints, and difficulty demonstrating value for money. Understanding the pathway allows commissioners to identify gaps, write effective service specifications, and hold providers accountable for clinically appropriate care.
Why Commissioners Should Understand the Pathway
Commissioning ADHD services without a detailed understanding of the NICE diagnostic pathway is like building a house without a blueprint. You need to know each room's purpose before you can fill it. Here are three specific reasons why commissioners should invest time in learning the pathway.
First, understanding the pathway helps you identify gaps in local service capacity. If your area has long waiting times for assessment, the bottleneck is often at step two or three of the pathway. Knowing which step is failing allows you to target your procurement accordingly.
Second, it enables informed procurement of assessment services from independent providers under Right to Choose or block contracts. When you understand the clinical requirements for each step, you can evaluate whether a provider can deliver assessment, diagnosis, and post-diagnostic support to the standard NICE expects. This is particularly relevant given the rise of Right to Choose referrals, which we have covered in our guide on Right to Choose ADHD explained for UK commissioners and providers in 2026.
Third, knowledge of the pathway builds credibility with clinical leads. When you speak the same language as your consultant psychiatrists and nurse specialists, you can have more productive conversations about service redesign, capacity planning, and outcome measurement.
Step by Step Guide to the NICE ADHD Diagnostic Pathway
The NICE ADHD diagnostic pathway can be broken down into five core steps. Each step has specific clinical and workforce requirements that commissioners must consider.
Step 1: Recognition and Referral
ADHD is often first suspected in primary care or school settings. NICE recommends that recognition should be based on validated screening tools and questionnaires, not on informal observation alone. In children and young people, the Strengths and Difficulties Questionnaire (SDQ) is commonly used. For adults, the Adult ADHD Self-Report Scale (ASRS) is a starting point.
Once a patient screens positively, a referral should be made to a specialist service. Commissioners need to ensure that referral pathways are clear and that patients are not lost between services. GPs must know where to send referrals, and the receiving service must have capacity to triage them promptly.
Step 2: Specialist Assessment
This is the most resource-intensive step. A trained clinician must conduct a comprehensive assessment using DSM-5 or ICD-11 diagnostic criteria. The assessment includes a structured clinical interview, collateral history from family or school, and validated rating scales. For autism co-morbidity, NICE recommends that the assessment should also consider the use of ADOS-2, though ADOS-2 is not mandatory for every ADHD assessment.
The workforce challenge here is acute. There are not enough clinicians trained in ADHD assessment, particularly those skilled in ADOS-2 for neurodevelopmental overlap. This is where specialist recruitment agencies such as Vantis can source ADHD assessors who are familiar with NICE guidelines and Right to Choose requirements. We cover this in more detail later.
Step 3: Diagnosis and Communication
Once the assessment is complete, the clinician makes a diagnosis and communicates it clearly to the patient and to the GP. This communication should include a shared care agreement template if medication is to be initiated. The shared care agreement must be agreed by the GP, the specialist, and the patient before any prescription is handed over.
Commissioners should ensure that their commissioned providers have standardised shared care templates to reduce GP pushback. A poorly drafted template can delay treatment by weeks or months.
Step 4: Post-Diagnostic Support
Diagnosis is not an endpoint. NICE recommends that all patients receive psychoeducation about ADHD, its management, and the implications for education or employment. This may include group sessions, written resources, or one-to-one coaching.
Medication initiation, if appropriate, should be carefully managed by a specialist. Titration of stimulants or non-stimulants requires close monitoring for side effects and efficacy. The workforce here includes specialist nurses and prescribing clinicians. Without enough of these professionals, services can cap the number of new patients entering the treatment phase, even if assessments are completed.
Step 5: Ongoing Monitoring and Review
After titration is complete, patients on medication require regular monitoring, typically every six months or annually, to check blood pressure, heart rate, weight, and mental health. This monitoring can be delivered under shared care arrangements with the GP, provided the GP has accepted the shared care agreement.
Commissioners should build annual review capacity into their service specifications. If the shared care agreement is not accepted, the specialist service may need to retain responsibility for monitoring, which increases demand on their workforce.
Common Challenges Commissioners Face and How to Overcome Them
Even the best designed ADHD pathway can fail if the workforce is not there to deliver it. The most common challenges are:
- Workforce shortages. There is a national shortage of ADHD assessors (including ADOS-2 trained clinicians), ADHD specialist nurses, and prescribing clinicians. These professionals are in high demand and short supply.
- Long waiting times. In many areas, waiting times for initial assessment stretch beyond 18 months, sometimes to two or three years. This is largely due to insufficient assessment capacity.
- Shared care agreement complexity. GPs are increasingly refusing to accept shared care because the templates lack standardisation or because they perceive the risk as too high. Commissioners must work with providers to produce clear, legally sound templates.
- Poor data collection. Without consistent data on referral rates, assessment times, and outcomes, it is impossible to evaluate whether commissioned services are meeting targets.
How can commissioners overcome these challenges? One proven approach is to commission independent providers who have existing clinical capacity and experience with Right to Choose pathways. A recent article on how private ADHD providers can cut NHS waiting lists provides practical examples of how block contracts and spot purchasing can rapidly reduce wait times. Another approach is to use specialist recruitment to fill the gaps in your own commissioned service.

Frequently asked questions
What is the NICE ADHD diagnostic pathway?
The NICE ADHD diagnostic pathway, defined in guideline NG87, is the recognised standard for diagnosing and managing ADHD in England and Wales. It covers the steps from initial recognition through specialist assessment, diagnosis, post-diagnostic support, and ongoing monitoring. Commissioners use it to ensure local services meet clinical and regulatory requirements.
How can commissioners reduce ADHD waiting times?
Commissioners can reduce waiting times by increasing assessment capacity. This can be done by commissioning independent providers with proven experience in ADHD assessment, particularly those operating under Right to Choose frameworks. Another effective method is to use specialist recruitment agencies to deploy ADOS-2 trained assessors and ADHD specialist nurses directly into existing services.
What are the steps in the NICE ADHD assessment process?
The assessment process includes five key steps: recognition and referral from primary care or schools; specialist assessment using DSM-5 or ICD-11 criteria; diagnosis and communication of the outcome to the patient and GP; post-diagnostic support such as psychoeducation and medication initiation; and ongoing monitoring and review under shared care or specialist-led management.
Why do commissioners need to understand ADHD pathway?
Understanding the ADHD pathway allows commissioners to identify capacity gaps, write accurate service specifications, and evaluate provider bids against clinical standards. It also helps commissioners build credibility with clinical leads and ensure that commissioned services deliver safe, effective care that meets NICE recommendations.
