Under Federal and State regulations, the highest technical and professional levels of therapeutic assessment and clinical treatment are restricted to accredited Clinical Psychologists.

Psychological assessment and diagnosis
Clinical psychologists have specialist training in the assessment and diagnosis of major mental illnesses and psychological problems. Through their specialist training, clinical psychologists are qualified to provide expert opinion in clinical and compensation areas.

Treatment
Clinical psychologists are trained in the delivery of a range of techniques and therapies with demonstrated effectiveness in treating mental health disorders. They are specialists in applying psychological theory and scientific research to solve complex clinical psychology problems requiring individually tailored interventions.

Research, teaching and evaluation
Research, teaching and evaluation are all integral to the role of clinical psychologists. Research is often conducted on prevention, diagnosis, assessment and treatment. Clinical psychologists are involved in the design and implementation of treatment strategies in various settings (such as primary care, psychiatric and rehabilitation) and in the subsequent evaluation of treatment outcomes.
