Complex Psychological Assessment

Complex Psychological Assessment

The Complex Psychological Assessment service offers essential, in-depth psychological assessments for clients presenting with complex presentations of mental health, trauma, personality, neurodevelopmental, neurocognitive/neuropsychological, and forensic concerns. A dedicated team of highly experienced professionals, registered psychologists specialising in clinical psychology and clinical neuropsychology, will manage each assessment.

Our team of experts also actively contributes to the field through teaching and research in advanced clinical psychological assessments. What sets us apart is our commitment to a neurodiversity-affirming approach, ensuring each client receives an inclusive and well-rounded evaluation.
