Autism Diagnosis

Autism Diagnosis for Children under 18

Berkshire Healthcare NHS Foundation Trust’s CAMHS service manages the Autism Assessment Pathway, which assesses whether a child or young person has an autism spectrum condition.

Click here for full details of the Pathway process and the Trust’s Autism Assessment Team.

The wait for an assessment is 18 to 24 months. Parents and carers are welcome to attend our workshops once their child has been accepted on the CAMHS waiting list.

Berkshire CAMHS has produced this short video outlining the assessment process, to help parents and children

If you have concerns that a child may have autism, speak to your GP, health visitor or, if the child is attending school, a teacher. All these professionals will be able to refer you for further advice.

If your child is on the Berkshire CAMHS waiting list for an autism assessment appointment, you can attend our NAS Autism Seminars for Families, which provide practical advice and strategies to use while you wait. These workshops are free of charge to participants, thanks to funding from the Berkshire NHS clinical commissioning groups.
