The waiting time standard recommended by the National Institute for Health and Care Excellence (NICE) is for a maximum waiting time of 13 weeks between a referral for an autism assessment and a first appointment. NICE guidelines on attention deficit hyperactivity disorder (ADHD) do not recommend a maximum waiting time standard from referral for an assessment of ADHD to assessment.

The Government has recognised that, nationally, demand for assessments for autism and ADHD has grown significantly in recent years and that people, including children, are experiencing severe delays for accessing such assessments. The Government’s 10-Year Health Plan will make the National Health Service fit for the future, and reforms to the Special Educational Needs and Disabilities (SEND) focus will improve early intervention and support.

It is the responsibility of integrated care boards (ICBs) to make available appropriate provision to meet the health and care needs of their local population, including provision of autism and ADHD services, in line with relevant NICE guidelines.

Through the NHS Medium-Term Planning Framework, published 24 October 2025, NHS England has set clear expectations for local ICBs and trusts to improve access, experience, and outcomes for autism and ADHD services over the next three years, focusing on improving quality and productivity. The framework was explicit that ICBs and providers are expected to optimise existing resources to reduce long waits for ADHD and autism assessments and improve the quality of assessments by implementing existing and new guidance, as published.

In December 2025, my Rt Hon. Friend, the Secretary of State for Health and Social Care, launched the independent review into the Prevalence and Support for mental health conditions, ADHD, and autism. The review is chaired by Professor Peter Fonagy, with Vice Chairs Professor Sir Simon Wessely and Professor Gillian Baird.

The review’s interim report, published at the end of March, sets out the evidence reviewed so far on prevalence, describes the impact of rising demand for diagnosis and support, identifies where the evidence is uncertain, and outlines the key questions for the next phase. It does not offer final conclusions or recommendations.

The final report, due in the summer, will make recommendations on how the Government, the health system and wider public services can respond to increasing demand for support more fairly and effectively so that people receive the right support, at the right time, in the right place.
