NICE-Guidance recommended assessment

By the time a parent searches for an autism assessment for their child their journey has already been going on for some time. You likely have already done your research, heard from school and had advice from well-meaning others. It can feel like a bit of a minefield. The reality is you are searching because you want to help your child get the support they need to be the best version of themselves, now and for the future. That support often starts with, or can even require, an evidence-based multi-disciplinary autism assessment and diagnosis. Our team have many years experience in specialist autism services in the NHS. They offer a gold-standard comprehensive assessment privately using the most up-to-date tools and findings.

Further or ongoing support

Our focus is on helping your child, and on helping you to steer them along their way as they continue to develop. The process of growing up is full of challenges, but also opportunities. We are here whether your child has an official diagnosis or not, to help guide you both along that path. We work with our extended team of specialist child and adolescent clinical psychologists several of whom are experienced at offering therapy to children and young people with autism. We can offer specific ‘blocks’ of sessions around a particular tricky time or we can see you on a more ad-hoc basis as the need arises to pre-empt important transitions (e.g. the move to secondary school) or migrate skills previously learnt to newer situations as your child ages.

What’s involved

We use National Institute for Health and Care Excellence (NICE) guidelines to provide a multi-disciplinary autism assessment, using direct observation of your child’s behaviour and information from those individuals who know your child well, including you as parents.

  • Stage 1 - The assessment process will start with a screening telephone call lasting an hour, from one of our Clinicians. This screening process will help us to understand your child’s difficulties and whether we feel a full autism assessment is required. If not, we will discuss this with you.
  • Stage 2 - Should we feel that your child does require a full autism assessment, we will seek information from nursery or school, and conduct a formal interview with you.
  • Stage 3 - A formal observation of your child will also take place, using an Autism Diagnostic Observation Schedule, Second edition (ADOS-2). This is likely to take place in our clinic and may last up to an hour.
  • Stage 4 – Should we require further information, we may also conduct an observation of your child either in their nursery setting or at school (depending on your child’s age).
  • Stage 5 – The team will meet to discuss the information collated, and a decision will be made as to whether your child meets the criteria for a diagnosis of Autism Spectrum Disorder.
  • Stage 6 – You will be invited to attend a feedback session with both Dr Nikkita Osiadacz and Melissa Dean to discuss the assessment findings and to think about recommendations for your child and support going forwards.
  • Stage 7 – A full report of the assessment and findings will be produced.

Ongoing support and check-ins

Our support and involvement does not need to end when the assessment is over. We are fortunate to have a team of additional specialist child and adolescent clinical psychologists working right here with us who can join to offer individualised support for your child or family either straight after the assessment or at helpful times in the future (or both). We are your back-up support as time goes by, using our in-depth familiarity with your child and your family to help navigate future challenges and opportunities. Meaning you don’t need to start from scratch.
