Our assessments are delivered using the 'Gold Standard' ADIR and ADOS instruments. 

We can start your assessment within 2 weeks of you contacting us.  

Following your assessment a report will be produced which will contain a detailed analysis of our finding.


If an ASC is diagnosed we will provide recommendations of which interventions are most likely to improve the management of an ASC.

Our interventions include:

  • Psychological Support
  • Counselling
  • Coaching
  • Educational Support
  • Behavioural Strategies
  • Speech and Language Therapy


Our Practice has the expertise of  psychologists, counsellors and speech and language therapists, all of whom have experience with autistic spectrum conditions.

We can offer a range of support packages that are tailored to your individual needs, aims and ambitions.


We also offer payment plans to help spread the payments of your assessment over an agreed duration.  We do not charge interest for this arrangement.

Benefit of an assessment

Children who have been assessed by us have been offered additional support and help with learning.  We have engaged schools and offered face to face meetings to discuss the interventions ensuring we give the best level of service possible.

For their families it can improve understanding of their child’s behaviour, giving them the answers to a lot of questions.

As part of the report following the assessments we put forward helpful strategies and interventions with new ways to engage and communicate with your child.

For adults it can open the door to further support and funding from the local authority* It can help employers understand and support them more effectively particularly with the legislation that covers how they should treat employees with disabilities. 

Finally it can lead to understanding some of the difficulties they had holding down a job or making relationships in the past and help them more forward.
