ADHD & ASD Assessment Inclusion/Exclusion Criteria 

General Criteria (applies to both Adults & Children) 

  • The individual must be registered with a GP to ensure follow-up care and communication. 
  • The referral can come from self-referral, a parent/carer, GP, school, or another healthcare professional. 
  • The individual should not have significant unmanaged mental health conditions that would impact the accuracy of assessment (e.g., acute psychosis, severe depression with active suicidal intent). 
  • The individual must not have a previous formal diagnosis, unless seeking reassessment due to significant concerns about the original outcome. 

Child & Adolescent ADHD and ASD Assessment (Ages 7-17) 

  • The child must be aged 7 years or older for remote ADHD/ASD assessment (as per NICE Guidelines). 
  • The child should not have a severe learning disability (i.e., IQ below 50), as this may require a specialist neurodevelopmental team. 

Adult ADHD and ASD Assessment (Ages 18+) 

  • The individual must be aged 18 or older at the time of referral. 
  • If the individual has complex co-existing mental health conditions (e.g., severe PTSD, schizophrenia), they should be stable on treatment before undergoing assessment to ensure diagnostic accuracy. 

Exclusion Criteria (when an assessment would not be suitable) 

  • Individuals with a current crisis, acute suicidal risk, or severe unmanaged mental health disorder requiring urgent intervention. 
  • Individuals with ongoing substance misuse that could significantly impact the reliability of assessment outcomes. 
  • Individuals already diagnosed with ADHD or ASD and seeking only a reassessment for medication or benefits purposes without clinical justification. 
  • Children under 7 years old. 
  • Individuals seeking an assessment for court/legal purposes, as we do not provide forensic assessments. 
  • Individuals with a known acquired brain injury or severe neurodevelopmental conditions (e.g., profound intellectual disability, genetic syndromes) where standard diagnostic tools may not be appropriate.
