Apply the due professional care standard to engagement staffing

Key idea: Due professional care means applying the care and skill a reasonably prudent auditor would use, including making sure the team has the expertise that a complex or specialized subject requires.

How to reach the answer

1. The question asks which action shows the care and skill applied to the engagement as a whole, not which test step is routine.
2. Workplace accident claims involve medical and occupational health judgments that general auditors usually lack.
3. A prudent auditor recognizes that gap and adds a specialist, which reflects due care for complexity and significance.
4. Options B and D are ordinary audit procedures, and option C is uncritical reliance, which works against due care.

Each option

• ACorrect. Adding an occupational health specialist shows the team considered how complex the subject is and made sure it had the expertise to judge the claims competently.
• BIncorrect. Checking claim classification is a standard test step and does not specifically show the prudent care and skill the standard asks for.
• CIncorrect. Accepting reports from the claimant's own doctor without question shows a lack of professional skepticism, which is the opposite of due care.
• DIncorrect. Confirming that accidents happened at work is a normal validity test, and the team cannot do it well without the right expertise anyway.

Common trap: Option D sounds rigorous and fraud-focused, so candidates may treat a thorough test step as due care, overlooking that due care starts with having the competence to judge the evidence.

In practice: When engagements cover health and safety, actuarial, IT security, or engineering areas, the CAE often brings in guest auditors or outside specialists so the team's conclusions hold up.

Remember: Due professional care includes recognizing when a subject needs specialist expertise and getting it, rather than relying on unqualified judgment.
