Our Adult Assessment Services

Cornwall Autism and Neurodevelopment (CAN) offer two adult autism assessment options for individuals to choose from; a face to face or hybrid assessment – both of which can be tailored to fit your your needs.


      • Simply contact us via email to refer yourself or family member for a private ASD assessment from Cornwall Autism and Neurodevelopment (CAN).


      • We will email a client form to complete to provide us with examples of strength and difficulty both currently and in the past.
      • We will request copies of any other reports you have from health or other professionals.
      • We will also email a form for a family member/friend/colleague to provide us with information about the client, ideally including historical observations.
      • We will email a link for the Social Responsiveness Scale – 2 (SRS-2), an online standardised ASD questionnaire, for the client to complete.
      • If the client or informant is unable to complete forms, just get in touch, and we will make accommodations.
      • Once all this information is returned we will hold a screening meeting and then get in touch with our client with our thoughts on their presentation.
      • If at this point we do not think an assessment from Cornwall Autism and Neurodevelopment (CAN) is indicated, for instance if there is not enough evidence of ASD or if we feel alternative support would be in the best interests of the individual we will signpost you to appropriate services, including local NHS and council support. 
      • If we all agree that an independent ASD assessment could be helpful we will arrange a date and time that is convenient for the next stage of our assessment.


      • Family Member Interview We will arrange a time to meet either online via a secure video platform or face to face to gather information on the individual’s presentation and to get a detailed developmental history if possible.  This assessment can take up to 3 hours.
      • ADOS Assessment and Clinical Interview This will take place at our clinic room at the Health and Wellbeing Innovation Centre, Truro, or at Market Hall, Devonport, Plymouth. This lasts between 1 -2 hours.


      • Once both assessments have taken place we will then hold multidisciplinary diagnostic discussions during which our observations, and the information gathered are considered using the Diagnostic and Statistical Manual of Mental Disorders, 5th Edition (DSM5) to determine whether the criteria for a diagnosis of ASD have been met.


      • We will phone with the outcome of the assessment within a week of the final assessment session.
      • We will email a detailed report including recommendations and signposting.


      • Finally, we offer a feedback meeting, this takes place online with one of our experienced clinicians and is an opportunity to ask us any questions about the assessment, report, recommendations and next steps.
