School Visits

Child Education Psychologist - School visitsWherever possible, Dr Dyer conducts visits to a child’s current educational setting to observe and assess the teaching and learning context, and to assess the suitability of the provision for the child. Visits always include professional discussions with relevant school staff.

Visits are scheduled for 2-3 hours, and a written report with recommendations is provided. You should allow between 3 and 4 hours of time costs in total for this work.

Where parents are seeking a change of placement, Dr Dyer visits both the current school placement and parents’/LA preferred placements. This will incur about 2-3 hours of additional time costs per school visit and 1-2 hours for the report of the visit.

Diagnoses and specialist assessments for Pathological Demand Avoidance Syndrome

PDA AssessmentsDr Dyer has extensive experience and expertise in the diagnosis and assessment of Pathological Demand Avoidance Syndrome (PDA).

Her robust assessments include:

  1. The review of existing professional reports
  2. Observation and assessment of the child in the home setting
  3. Observation and assessment of the child in their educational setting
  4. Discussions with school staff
  5. Parental Interview

Detailed reports set out her professional opinion in relation to the current diagnostic criteria for the condition.

Dr Dyer can assess children from 4 to 16 years who may have this condition. There may be a pre-existing diagnosis of Autism, or Atypical Autism, which does not match the child’s presentation. If you think your child is presenting with PDA, please read the article by Margo Duncan, which you can download here or on my resources page, for more information.


This extensive assessment takes several hours usually over two days. Please contact me to discuss your individual requirements.
