About the assessment if you are referred to the Emotional Health Service

You will be seen locally in Richmond and Kingston (assessments take place at Moor Lane and at York Street Twickenham).  The service accepts a set number of cases for ASC and ADHD assessment per month as agreed with local health commissioners.


Several pieces of evidence are collected in order for cases to be triaged and accepted onto the assessment list. These include a developmental history form from parents, a school report form, a social communication questionnaire, a strengths and difficulties questionnaire and Conners rating scales. These are all required before a decision will be made about accepting for assessment. 

The pathway for ASC assessment is in three parts:

  • An interview with parents.
  • An Autism Diagnostic Observation Schedule (ADOS) with the child or young person.  This is a semi-structured assessment between the child or young person and the clinician.    There is also usually an observer present from our clinical team. 
  • Feedback with parents and the young person (dependent on the young person’s age).

The diagnosis is made taking into account the parental interview, ADOS or BOSA assessment, school report and other evidence. A comprehensive report is written following assessment and includes the diagnosis.

For ADHD assessments the assessment is in three parts: 

  •    A school observation or interview with school staff on the telephone if an observation is not possible
  •    A face to face interview with parents and with the young person 
  •    Feedback with parents and the young person (dependent on the young person’s age).

The diagnosis is made taking into account the clinical interview, school report and observation and other evidence. A comprehensive report is written following assessment and includes the diagnosis.

Kingston and Richmond CAMHS acceptance criteria for a private diagnosis for Autism/ADHD

The following information sheet is aimed towards providing caregivers and professionals with basic information regarding gold/ best-practice standards for a diagnosis of Attention Deficit Hyperactivity Disorder (ADHD) and Autism Spectrum Disorder (ASD). If a child or young person has been given a diagnosis of ADHD and/ or ASD by a private practitioner (e.g. non-NHS clinician), their written diagnostic report should meet the same standards as a diagnosis provided by NHS assessment services. Gold standards are determined through an assessment’s compliance with the guidelines put forth by the National Institute for Health and Care Excellence (NICE).

Feedback from parents and carers

  • Great to have a quicker, more efficient service.
  • It has been a fast and straightforward process which has been a pleasant surprise.
  • We felt that we weren’t rushed and further appointments were made, rather than comprising the information.
  • It felt that proper time and consideration was given to us all.
  • The staff both listened to me, they spoke with a nice tone and were there for me and were extremely kind and put me at a lot of ease.
  • Very supportive environment established straight away.
  • My son was treated with respect and not patronised at all. Staff that are easy to talk to, sympathetic to my child’s needs and accommodating.
  • Felt informal and relaxed.
