Ethics and Professional Practice accounts for 4-6 of the 110 questions on the FE Civil exam. These are the cheapest points available, because they require no calculation and no handbook lookup, and candidates still lose them by answering with instinct rather than with the code of ethics the question is testing.
The problems below are scenario-based, the way NCEES writes them: an engineer receives a gift, discovers a defect, is asked to seal work they did not supervise, or is offered a job outside their competence. The solutions explain which specific obligation controls the answer and why the plausible-sounding alternative fails.
Exam weight: NCEES lists Ethics and Professional Practice at 4-6 questions of the 110-question FE Civil exam. Work each problem below on paper first, then reveal the worked solution — reading a solution you have not attempted builds recognition, not recall.
What NCEES Tests in Ethics and Professional Practice
The specification covers codes of ethics, professional and technical societies, and ethical and legal considerations including agreements and contracts. Questions test the hierarchy of obligations: public health, safety and welfare comes first, then the client and employer, then the profession, then yourself. When two obligations conflict in a scenario, the ranking is the answer. Expect items on conflicts of interest, gifts, confidentiality, and truthful public statements.
You will also see licensure and professional practice content drawn from the NCEES Model Law and Model Rules: the difference between an engineer intern and a licensed PE, what a seal signifies and who may apply one, practicing only in areas of competence, and continuing education. Contract questions stay at the concept level, covering the elements of an agreement, breach, and basic professional liability rather than legal detail.
5 Free Ethics and Professional Practice Practice Problems
Each ethics problem below comes from the FEExamClick FE Civil question bank, with worked solutions, and matches the style, difficulty and format of the real exam. Attempt each one under a three-minute limit — roughly the pace the exam demands.
Problem 1 — A. Codes of ethics (professional and technical societies)
An engineer is offered a geotechnical design assignment but has no training/experience in soil mechanics. What is the best ethical response?
Answer: C) Undertake assignments only when qualified by education or experience in the specific field
Step 1 – Identify the ethical issue: An engineer with no training in soil mechanics is offered a geotechnical design assignment. This tests the rule on professional competence before accepting work.
Step 2 – Relevant rule: NCEES Model Rules §240.15(B)(1): "Licensees shall undertake assignments only when qualified by education or experience in the specific technical fields involved." This is distinct from general engineering competence — it requires qualification in the specific field of the assignment.
Step 3 – Apply the rule: Geotechnical engineering is a specialized discipline. An engineer without education or experience in soil mechanics is not qualified to perform geotechnical design, regardless of their general engineering background. Accepting such an assignment could endanger the public and constitutes a violation of the competence rule.
Step 4 – Why other options are wrong:
(A) Accepting work as a learning opportunity is not the same as being qualified — the rule requires prior qualification, not on-the-job training at the client's expense.
(B) Having another engineer review the work does not make the original engineer qualified; the review engineer should be the one performing the work.
(D) Informing the client of your inexperience may be honest, but it does not fulfill the requirement to be qualified before undertaking the assignment.
Correct answer: (C)
Problem 2 — A. Codes of ethics (professional and technical societies)
A PE learns that a subcontracted surveying firm is falsifying field notes. What is the most ethical next step?
Answer: B) Report the suspected violation to the board and cooperate as requested
Step 1 – Identify the ethical issue: A PE has discovered that a subcontracted firm is falsifying field notes. This tests the duty to report violations of professional rules or laws.
Step 2 – Relevant rule: NCEES Model Rules §240.15(A)(8): "Licensees who have knowledge or reason to believe that any person or firm has violated or is violating any of the provisions of the rules of professional conduct shall report such knowledge or reason to believe to the appropriate licensing board and shall cooperate with the licensing board in furnishing such further information or assistance as may be required."
Step 3 – Apply the rule: Falsifying field notes is a clear violation of professional conduct rules. The PE is not excused because the violator is a surveying firm rather than an engineering firm — the duty to report applies whenever the PE has knowledge or reason to believe a violation has occurred. The PE must report to the board and cooperate fully.
Step 4 – Why other options are wrong:
(A) The misconduct is not strictly "engineering," but the PE still has knowledge of a professional rules violation and has a duty to report it.
(C) A private warning does not satisfy the duty to report to the licensing board and allows the violation to continue.
(D) Waiting until after the project finishes delays the report unnecessarily and could allow further violations or public harm.
Correct answer: (B)
Problem 3 — A. Codes of ethics (professional and technical societies)
An engineer's spouse owns stock in a supplier being considered for the engineer's project. What is the ethical requirement?
Answer: B) Disclose known or potential conflicts of interest that could influence or appear to influence judgment
Step 1 – Identify the ethical issue: An engineer's spouse holds stock in a supplier under evaluation for the engineer's project. This tests the conflict-of-interest disclosure requirement.
Step 2 – Relevant rule: NCEES Model Rules §240.15(B)(6): "A licensee shall disclose to employers, clients, or other affected parties all known or potential conflicts of interest or other circumstances which could influence or appear to influence the licensee's judgment or the quality of services."
Step 3 – Apply the rule: Even though it is the spouse's investment, a financial interest in the household that could benefit from the engineer's recommendation creates a real or apparent conflict. The rule covers circumstances that "appear to influence" judgment, not just those that actually do. The engineer must proactively disclose this situation to the client or employer so an informed decision can be made about the engineer's role.
Step 4 – Why other options are wrong:
(A) A spouse's financial interests can create an apparent conflict of interest that must be disclosed — the rule is not limited to the engineer's personal holdings.
(C) Full withdrawal from engineering is far more drastic than necessary; disclosure is the required first step.
(D) Waiting to be asked transfers the burden to the client, but the rule places the proactive duty to disclose on the licensee.
Correct answer: (B)
Problem 4 — A. Codes of ethics (professional and technical societies)
A licensee sits on a government body and is also employed by a private firm seeking work from that body. What must the licensee do?
Answer: A) Not participate in decisions regarding services offered by their private concern to that governmental body
Step 1 – Identify the ethical issue: A licensee sits on a government body and is employed by a private firm that wants to provide services to that same body. This tests the rule on participation in governmental decisions affecting one's private employer.
Step 2 – Relevant rule: NCEES Model Rules §240.15(B)(8) also states: "A licensee who is a member of a governmental body shall not participate in the decisions of that body concerning the employment of or the services to be provided by the licensee's private concern to that governmental body."
Step 3 – Apply the rule: Even if the licensee only abstains from voting, "participation" in the decision-making process is prohibited. This includes discussions, recommendations, and procedural decisions — not just the final vote. The only compliant course is complete non-participation in any decisions related to the private firm's potential work.
Step 4 – Why other options are wrong:
(C) Abstaining from the vote is not sufficient — the rule prohibits participation in the full decision-making process, not just the vote itself.
(B) The firm being the lowest bidder does not exempt the licensee from the non-participation requirement; the conflict exists regardless of bid ranking.
(D) Disclosure and then voting is expressly contrary to the rule, which prohibits participation outright rather than allowing it with disclosure.
Correct answer: (A)
Problem 5 — A. Codes of ethics (professional and technical societies)
A licensee receives a "finder's fee" from a supplier for steering a client to buy their product, without disclosure. This most directly violates:
Answer: A) Disclosure of conflicts of interest / circumstances that could influence judgment
Step 1 – Identify the ethical issue: A licensee secretly receives a financial incentive from a supplier for steering a client toward that supplier's product. This is a classic undisclosed conflict of interest that compromises professional independence.
Step 2 – Relevant rule (NCEES Model Rules §240.15(A)(6)): "Licensees shall disclose to their employer or client known or potential conflicts of interest or other circumstances which could influence or appear to influence their judgment or the quality of their services."
Step 3 – Apply to the scenario: Receiving a secret finder's fee from a supplier while recommending that supplier to a client is a textbook conflict of interest. The licensee's recommendation to the client is supposed to be based on merit and professional judgment. A hidden financial incentive corrupts that judgment — or at minimum appears to corrupt it — which is precisely what this rule requires disclosure of.
Step 4 – Why the other options are wrong:
(B) Confidentiality rules protect client information from disclosure to outside parties — they do not apply to the licensee's own undisclosed conflicts of interest with the client.
(C) Reporting obligations (§240.15(B)(8)) require reporting others' violations to the board — they do not govern the licensee's own undisclosed financial arrangements.
(D) Public opinion rules (§240.15(B)(5)-(6)) govern public statements — not private financial arrangements with suppliers during client service.
Correct answer: (A)
Using the FE Reference Handbook for Ethics and Professional Practice
The Ethics section of the handbook is short and worth reading start to finish before exam day, which is not true of any other chapter. It contains the NCEES Rules of Professional Conduct (Model Rules Section 240.15) and excerpts of the Model Law. During the exam, search for licensee, seal, or conflict to jump straight to the governing language. Because these questions have no formulas, the handbook is used for confirming the exact wording of an obligation, not for finding an equation.
Four Mistakes That Cost Points
- Answering with what a good employee would do Loyalty to an employer is a real obligation, but it ranks below public safety. Scenarios are built so the workplace-friendly answer conflicts with the code. If a supervisor asks you to bury a finding that affects safety, the correct answer is never the one that keeps the peace, no matter how reasonable it sounds.
- Treating small gifts as automatically acceptable Candidates often reason that a lunch or a modest item is harmless. The code addresses gifts that could influence, or appear to influence, professional judgment, and questions usually build in a pending decision. When a vendor gift arrives while their bid is under evaluation, the value of the item is not the deciding factor.
- Confusing an EI or EIT with a licensed engineer Passing the FE and receiving the engineer intern designation does not permit sealing documents, offering engineering services to the public, or calling yourself an engineer where that title is protected. Questions probe this directly. Know what the intern designation actually authorizes under the Model Law before exam day.
- Sealing or approving work outside your competence Scenarios present an engineer offered a project in an adjacent discipline, often with the reassurance that they can learn it. The code permits taking such work only with qualified collaboration or after acquiring competence. Sealing plans prepared by someone else whose work you did not direct is a separate violation, and both appear on the exam.
Frequently Asked Questions
How many ethics questions are on the FE Civil exam?
NCEES specifies 4-6 questions from Ethics and Professional Practice out of 110. It is a small share, but these questions take under a minute each when you know the code, which banks time for the calculation-heavy areas. Treat them as points you can secure with a few hours of focused reading.
Which code of ethics does the FE exam test?
Questions are built on the NCEES Model Rules of Professional Conduct, which are reproduced in the FE Reference Handbook. Other societies publish their own codes and the underlying principles align, but study the NCEES version because that is the language the exam uses. The Fundamental Canons and the ranking of obligations within them drive most answers.
Do ethics questions require the handbook?
You can answer most of them without opening it, but the handbook is available and contains the Model Rules. Use it when two answer choices both seem defensible. Reading the exact obligation usually resolves which one applies. The habit worth building is deciding the answer from principle first, then confirming against the text only when you are genuinely split.
Are contract and agreement questions really on the FE Civil exam?
Yes, at a conceptual level. The specification lists agreements and contracts under this knowledge area. Expect the basic elements that make an agreement binding, what constitutes breach, and general professional liability ideas such as standard of care. You do not need contract law depth. Recognizing terminology and the engineer's obligations under a professional services agreement is enough.
