Which professionals are specifically cited as examples of expert witnesses?

• A. Doctors, psychologists, nurses
• B. Parole officers
• C. Security guards
• D. Substitute teachers

Answer: (A)

Expert witnesses are those with specialized knowledge beyond everyday experience who can interpret complex issues for the decision-maker. In labor relations investigations, medical and mental health issues often require such expertise. Doctors, psychologists, and nurses have formal training, licenses, and clinical experience that let them assess injuries, disabilities, treatment options, prognosis, and how these factors affect an employee’s ability to work. Their testimony helps explain causation, impairment, and reasonable accommodations in a way that lay witnesses cannot.

The other roles listed typically provide observations or facts rather than expert opinions on medical or psychological matters. Parole officers, security guards, and substitute teachers may speak to events or behavior but do not ordinarily offer specialized medical or clinical interpretation. Hence, doctors, psychologists, and nurses are the cited examples of expert witnesses.
