Sample Ethics and Professional Practice questions
Try each one before opening the answer. Original questions written to the official exam objectives.
Question 1
An engineer is hired as an expert witness in a product-liability case. Under engineering ethics rules, the engineer's opinions on the stand should be:
- Alimited to the facts the hiring attorney has supplied and marked as relevant
- Bbased on adequate knowledge of the facts and a competent evaluation of the subject
- Cin line with the hiring party's position wherever the technical evidence is unclear
- Dwithheld on any point where an opposing expert has already given a contrary view
Show answer and explanation
Answer: B) based on adequate knowledge of the facts and a competent evaluation of the subject
Expert opinions must rest on adequate knowledge of the facts and a competent, honest evaluation. They must not be limited to what the client supplies or slanted toward the hiring party.
- AIncorrect. The engineer must have adequate knowledge of the facts, which may mean investigating beyond what the attorney chose to supply.
- BCorrect. The NCEES Model Rules say a licensee may give a professional opinion publicly only when it rests on adequate knowledge of the facts and a competent evaluation of the subject matter. Society codes add honest conviction.
- CIncorrect. Testimony must be objective and truthful. When the evidence is unclear, the engineer should say so, not settle the doubt in favor of whoever is paying.
- DIncorrect. A disagreement with another expert is no reason to stay silent. The engineer should give an objective opinion on every point within their competence.
Question 2
Partway through a feasibility study, a consulting engineer concludes that the client's planned waste-heat recovery system will probably not reach the energy savings the client is counting on. The design poses no safety hazard. What is the engineer's most appropriate action?
- AFinish the study as scoped without comment, since the client chose the system
- BTell the client about the concern and give the supporting analysis objectively and truthfully
- CPut the concern in an internal memo to protect the firm, but leave it out of the client report
- DReport the client's plan to the state licensing board before discussing it with the client
Show answer and explanation
Answer: B) Tell the client about the concern and give the supporting analysis objectively and truthfully
Engineers must be objective and truthful and include all relevant and pertinent information in their professional work. When a project probably won't meet the client's goals, the engineer should tell the client and explain why.
- AIncorrect. Holding back a significant conclusion leaves the study incomplete. Licensees must include all relevant and pertinent information in their professional documents and statements.
- BCorrect. The Model Rules require licensees to include all relevant and pertinent information in an objective and truthful manner in professional documents, statements and testimony. Telling the client is how the engineer meets that duty.
- CIncorrect. Keeping a material finding inside the firm protects the firm but leaves the client's report incomplete and misleading, which goes against the duty to be objective and truthful.
- DIncorrect. The plan poses no safety hazard and no one has broken a rule, so there is nothing to report to the board. The engineer's duty is to inform the client honestly.
Question 3
After a facility is built, a licensed engineer discovers an error in her sealed design calculations that could lead to a structural failure in service. Consistent with the NCEES Model Rules, her most appropriate first action is to:
- AReport the error to her firm's liability insurer and wait for counsel to approve any disclosure
- BPromptly inform the client and, as appropriate, the responsible authority so the hazard is addressed
- CRun a detailed failure-probability study first so that no one is alarmed by an unconfirmed concern
- DCorrect the calculations in the project file and apply the fix to future designs without notifying anyone
Show answer and explanation
Answer: B) Promptly inform the client and, as appropriate, the responsible authority so the hazard is addressed
Public health, safety, and welfare come first. An engineer who finds a dangerous error must promptly notify the client and appropriate authorities rather than delay, hide, or quietly fix it.
- AIncorrect. She may involve her insurer and counsel, but she can't hold back disclosure of a public safety hazard to limit liability. The public's health, safety, and welfare come first.
- BCorrect. A licensee's first responsibility is to safeguard the public. The Model Rules call for notifying the employer or client and other appropriate authorities when public safety is at risk.
- CIncorrect. Further analysis may be needed, but holding off notification while people may be at risk puts study ahead of public safety. The responsible parties need to know promptly.
- DIncorrect. Quietly changing records leaves the built hazard in place and misrepresents the design history. That breaks both the safety obligation and the duty to be truthful.
Question 4
While competing for a design contract, Engineer A tells the prospective client, without any specific evidence, that the rival firm's lead engineer "routinely cuts corners." A hopes the remark will win A the contract. Under the NCEES Model Rules of Professional Conduct, A's conduct is:
- APermitted, because statements made during proposal competition are treated as ordinary business speech
- BA violation only if the rival engineer actually loses the contract because of the remark
- CA violation of A's obligations to other licensees, regardless of who wins the contract
- DOutside the scope of licensure rules, because no public health or safety issue is involved
Show answer and explanation
Answer: C) A violation of A's obligations to other licensees, regardless of who wins the contract
The NCEES Model Rules forbid licensees from injuring or attempting to injure another licensee's reputation or prospects, maliciously or falsely. Making an unsupported attack on a competitor to win work breaks this obligation to other licensees.
- AIncorrect. Competing for work is no exception. The Model Rules forbid licensees from trying to injure another licensee's reputation or prospects maliciously or falsely, in any setting.
- BIncorrect. The rule covers attempts to injure as well as actual harm, so A's conduct is a violation whatever the outcome.
- CCorrect. Model Rules 240.15 C forbid injuring or attempting to injure, maliciously or falsely, the professional reputation or prospects of other licensees. They also forbid indiscriminate criticism of other licensees' work.
- DIncorrect. The Rules of Professional Conduct set out obligations to other licensees as well as to the public. Unfairly damaging a competitor's reputation is regulated conduct even when safety isn't involved.
Question 5
Offering a gift to a client's purchasing agent to win a contract is:
- ARequired for competitive bids
- BAcceptable if it's modest and customary
- CProhibited
- DFine if disclosed afterward
Show answer and explanation
Answer: C) Prohibited
- AIncorrect. It's prohibited.
- BIncorrect. Gifts to secure work are improper.
- CCorrect. Engineers may not offer gifts to secure work.
- DIncorrect. It's prohibited.
Question 6
A licensed engineer finds that a pressure-relief design her employer has approved could endanger the public. Management overrules her objection to keep the project on schedule. Which response best matches the NCEES Model Rules?
- ARecord her disagreement in the project file and then follow management's direction
- BNotify her employer or client, and any other appropriate authority, that her judgment was overruled
- CResign quietly, so she is not personally linked to the unsafe design
- DHold off on any action until the employer's legal department rules on the issue
Show answer and explanation
Answer: B) Notify her employer or client, and any other appropriate authority, that her judgment was overruled
Under the NCEES Model Rules, a licensee's first and foremost responsibility is to safeguard public health, safety and welfare. If her judgment is overruled where the public is endangered, she must notify the employer or client and any other appropriate authority.
- AIncorrect. Writing down her disagreement does not meet her duty. When her judgment is overruled where the public is endangered, she must notify the employer or client and any other appropriate authority.
- BCorrect. The Model Rules require licensees whose judgment is overruled where public health, safety or welfare is endangered to notify their employer or client and such other authority as may be appropriate.
- CIncorrect. Resigning without telling anyone leaves the hazard in place and does not meet the notification duty. Her first and foremost responsibility is to safeguard the public.
- DIncorrect. Leaving a safety-critical decision to the employer's legal department puts the employer's interests ahead of the public's. The duty to notify does not depend on the employer's legal review.
Question 7
After changing jobs, an engineer uses a former employer's confidential designs for the new employer. This is:
- AA breach of confidentiality
- BAcceptable if the designs aren't patented
- CStandard knowledge transfer
- DFine after six months
Show answer and explanation
Answer: A) A breach of confidentiality
- ACorrect. Confidential information must be protected.
- BIncorrect. Confidentiality still applies.
- CIncorrect. It's a breach.
- DIncorrect. It's a breach.
Question 8
An engineer is writing a design report and includes a stress analysis done by a coworker at the same firm. What should the engineer do about the coworker's contribution?
- AAcknowledge in the report that the coworker performed the stress analysis
- BLeave out any acknowledgment because work done by employees belongs to the firm
- CAcknowledge the coworker only if the coworker holds a professional engineering license
- DAcknowledge the coworker only if the client asks for a list of contributors
Show answer and explanation
Answer: A) Acknowledge in the report that the coworker performed the stress analysis
Ethics codes require engineers to give credit to the people who did the work. That duty applies no matter who owns the work, whether the contributor is licensed, or whether the client asks.
- ACorrect. Engineering ethics codes require that credit for professional work go to the people who actually did it.
- BIncorrect. Who owns the work and who gets credit are separate questions. Even if the firm owns the analysis, the person who did it should still get credit.
- CIncorrect. The duty to give credit doesn't depend on whether the contributor is licensed. Work by interns or unlicensed engineers gets credit too.
- DIncorrect. Giving credit is the engineer's own ethical duty. It doesn't wait for the client to ask.
Question 9
An engineer has a financial stake in a supplier being considered for a client's project. The engineer should:
- AAsk the supplier to lower its price quietly
- BRecommend the supplier without saying anything
- CSell the stake after the contract is signed
- DDisclose the interest to the client
Show answer and explanation
Answer: D) Disclose the interest to the client
- AIncorrect. That doesn't address the conflict.
- BIncorrect. That hides a conflict.
- CIncorrect. The conflict exists now.
- DCorrect. Conflicts must be disclosed.
Question 10
An engineer is being paid by an owner to design a plant expansion. The construction contractor offers to pay the engineer separately to prepare installation details for the same project. Under the NCEES Model Rules, the engineer may accept the contractor's payment:
- Aonly if the two fees together don't exceed the usual fee for the services
- Bonly if the contractor's work is a separate scope the engineer won't review
- Conly if it is fully disclosed to and agreed to by all interested parties
- Donly if the engineer reports the arrangement to the state licensing board afterward
Show answer and explanation
Answer: C) only if it is fully disclosed to and agreed to by all interested parties
Under NCEES Model Rules 240.15, a licensee may accept pay from more than one party on the same project only when the circumstances are fully disclosed and agreed to by all interested parties.
- AIncorrect. The rule is about the conflict of interest, not the size of the fees. A reasonable total doesn't remove the conflict.
- BIncorrect. Splitting the work into separate scopes doesn't satisfy the rule. The pay is still for services on the same project, so disclosure and agreement are still required.
- CCorrect. The NCEES Model Rules bar pay from more than one party for services on the same project unless the circumstances are fully disclosed and agreed to by all interested parties.
- DIncorrect. The interested parties (here, the owner and the contractor) must know and agree. Telling the board afterward doesn't meet that requirement.
