What signs might I see in my child?

Autism presents differently in every child, but these are the kinds of differences parents often tell us they've noticed:

  • Difficulty communicating, delay in developing speech or understanding language
  • Difficulty understanding emotions in others, reading facial expressions or understanding tone of voice
  • Differences in use of eye contact — they might avoid it, or it may appear more intense
  • Limited and often intense interests
  • Behavioural problems such as over-reactive to seemingly small triggers, physical aggression, frequent meltdowns
  • Strong preference for routine and struggles with change
  • A preference for playing alone
  • Sensory sensitivities (strong likes or dislikes for certain sensations) including a fussy or restricted diet
  • Sleep difficulties
  • Difficulties making or keeping friendships

Should I get my child assessed?

Reasons why your child might benefit from an autism assessment include:

  • Behavioural problems at home and/or at school
  • Concerns about slow academic progress at school
  • Difficulties managing social relationships
  • Showing signs of anxiety about attending school or school refusal
  • Family functioning is being significantly impacted by behaviours at home
Gold-Standard Assessment
We use the ADOS (Autism Diagnostic Observation Schedule) — the internationally recognised gold-standard play-based assessment tool — alongside a full developmental history and observation.

What does an assessment involve?

Three clear stages, designed around you and your child.

Before the Assessment

  • We ask you and your child's school to complete questionnaires
  • Review of any relevant reports from professionals who have seen your child, e.g. speech therapists, educational psychologists
  • A screening phone call, if needed, to discuss the best assessment for your child
  • A video call to take the developmental history from you as parents in advance, if you are concerned about speaking in front of your child

During the Assessment

Approximately 2 to 3 hours face-to-face at our Wallingford clinic, including:

  • Observation of your child's communication and interaction, plus a formal play-based assessment (ADOS)
  • A full history from you of your child's health and development
  • Growth assessment and physical examination of your child where applicable
  • Verbal feedback given on the day with the results of the assessment

After the Assessment

  • Observation of your child in their school setting may be arranged
  • A comprehensive report with a detailed explanation of the results and a list of recommendations and resources
  • Recommendations for your child's school and a copy of the report (amended as necessary) made available, which may facilitate additional support or an application for an EHCP
  • Follow up as necessary, including liaison with their school and attendance at school meetings to give advice, if required
