Definition
Child and Adolescent Mental Health Services are NHS services that assess and treat children and young people with mental health difficulties. CAMHS teams typically include clinical psychologists, child psychiatrists, mental health nurses, family therapists, and assistant psychologists, and operate across four historical "tiers", though most areas now describe themselves by service pathway rather than tier.
In context for parents
Key checkpoints
- CAMHS are NHS services assessing and treating children and young people with mental health difficulties.
- Tier model (Health Advisory Service, 1995): Tier 1 universal, Tier 2 targeted, Tier 3 specialist, Tier 4 in-patient. Many areas have moved to the i-Thrive needs-based model.
- In 2024–25, 1.6 million referrals in England with around 305,000 receiving treatment (NHS Digital); routine waits 6 months to 2 years.
- CAMHS will typically not see mild anxiety, behaviour difficulties without diagnosed mental illness, or learning difficulty alone.
- For young people approaching 18, NICE NG43 (2016) sets the transition planning standard from CAMHS to adult services.
The four-tier model (Health Advisory Service, 1995) framed CAMHS for three decades. Tier 1: universal services (GP, school nurse, health visitor). Tier 2: targeted CAMHS (typically one to two practitioners working with mild to moderate need). Tier 3: specialist CAMHS (multi-disciplinary teams handling moderate to severe presentations). Tier 4: in-patient and highly specialist services (regionally commissioned). Many areas have moved to a "i-Thrive" model that replaces tiers with four needs-based groupings.
In 2026, CAMHS is the bottleneck in UK paediatric mental health. NHS Digital data for 2023–24 showed 1.6 million referrals in England, with around 305,000 receiving treatment. Routine referral waits run 6 months to 2 years. Urgent referrals (eating disorders, severe self-harm, psychosis) typically meet four-week NHS access standards.
What CAMHS will and will not see:
- Will: moderate to severe anxiety, depression, OCD, self-harm, eating disorders, ADHD assessment in some areas, autism assessment in some areas, psychosis.
- Will not (in most areas): mild anxiety, behaviour difficulties without diagnosed mental illness, sensory needs, learning difficulty without mental health comorbidity.
- Many SEND families are referred to CAMHS and discharged at first contact with the message "not severe enough".
What CAMHS contributes to the EHCP:
- Where mental health is part of the SEND picture, CAMHS clinical advice can be a Section G health provision input.
- Section F should specify the school-side response to mental health need (key adult relationship, ELSA, therapeutic input).
- The CAMHS care plan, where one exists, should be referenced.
For young people approaching 18, the transition from CAMHS to adult mental health services is a known crisis point. NICE NG43 (2016) sets the transition planning standard; implementation varies widely.

Obsessive-Compulsive Disorder(OCD)
An anxiety-related condition involving intrusive, unwanted thoughts (obsessions) and repetitive behaviours or mental acts done to reduce distress (compulsions).
Clinical Psychologist

Where parents ask about this
Parents usually find this page after a CAMHS referral has been rejected, when CAMHS has discharged the child without a plan, or before an EHCP review where mental health is a core issue. Searches include "CAMHS rejected referral next steps", "private CAMHS UK", and "CAMHS to adult services transition". A Beaakon CAMHS-experienced clinical psychologist or mental health nurse can carry out the assessment NHS CAMHS will not, deliver evidence-based therapy, and write tribunal-grade evidence where mental health is core to the SEND case.
