Ethics & Professional Practice
The NCEES code of ethics, responsible charge, licensure and sealing rules, conflicts of interest, liability, and contract basics — the section of the exam with no calculations and the least forgiveness for a careless read.

The code of ethics in one hierarchy
The NCEES Model Law and Model Rules of Conduct are the framework behind every ethics question on the FE. The code is built as a hierarchy of duties, and the exam tests whether you know the ordering when two duties collide:
Public safety, health & welfare > employer/client > profession > colleagues
| Paramount duty | engineers shall hold paramount the safety, health, and welfare of the public in the performance of their professional duties |
| Loyalty to client | serve clients faithfully — but never by violating the paramount duty |
| Integrity of the profession | avoid deceptive acts, uphold the honour of the profession |
| Duty to colleagues | do not maliciously injure another engineer's reputation or practice |
When a question pits a client's wishes against public safety — a cheaper footing, a skipped test, a falsified report — the client always loses. If an answer choice involves endangering the public to please anyone, it is wrong.
Licensure, seals, and responsible charge
The FE exam expects you to know the machinery of professional licensing as described in the NCEES Model Law:
| Licensure by state | engineering licences are granted by individual state boards; a PE licensed in one state cannot practise in another without comity/endorsement |
| Responsible charge | an engineer may sign and seal only work performed under their responsible charge — direct personal control and supervision of the work |
| Sealing | the seal attests that the engineer takes professional responsibility for the document; sealing work you did not supervise or review is a violation |
| Competence | an engineer shall practise only in areas of their competence — a structural PE should not stamp electrical design they are not qualified in |
"Responsible charge" is the most-tested single phrase in this section. It means the engineer actually directed and supervised the work — not merely glancing at it, and certainly not signing plans drawn by someone else unseen.
Conflicts of interest
The rule is disclosure-first: an engineer with a conflict of interest must disclose it promptly to every affected party and proceed only with their informed consent. Common exam scenarios:
| Dual compensation | do not accept payment from more than one party for the same project unless all parties are fully informed and agree |
| Self-dealing | do not recommend or approve a supplier, contractor, or design in which you have a financial interest without disclosure |
| Side employment | moonlighting for a client of your employer, or work that competes with your employer's interests, must be disclosed |
| Confidentiality | do not disclose a client's or employer's confidential information to another party without consent |
Professional liability
Liability questions hinge on one concept: negligence is the failure to exercise the care that a reasonably prudent, competent engineer would exercise under similar circumstances. The exam's favourite traps cluster around this definition:
| Standard of care | measured against competent practitioners — an honest mistake is not automatically negligence, but falling below the professional standard is |
| Strict liability | rare in engineering; liability normally requires proof of negligence (a failure to meet the standard of care) |
| Statute of repose | limits how long after substantial completion a claim may be brought, regardless of when the defect is discovered |
| Indemnification | a contractual clause shifting responsibility for loss; overbroad indemnity clauses (covering another party's negligence) are an ethical red flag |
Contract basics
Engineering contracts questions test the formation and administration of contracts, not legal drafting:
| Offer + acceptance + consideration | the three elements of a valid contract — a proposal, agreement to it, and something of value exchanged |
| Consideration | the value each party gives (money, services, materials); a promise with no consideration is generally unenforceable |
| Fixed-price (lump-sum) | contractor bears the cost-overrun risk; engineer bears scope-creep risk |
| Cost-plus | owner reimburses costs plus a fee; owner bears the cost-overrun risk, and the fee structure must not reward inefficiency |
| Unit-price | owner pays per measured quantity; risk is shared — quantity risk sits with the owner, unit-cost risk with the contractor |
A written contract is not strictly required for validity — oral contracts can be enforceable — but engineering practice (and the exam) treats written agreements as the expected standard.
Worked scenario The cheaper footing
Situation: You are the engineer of record on a small commercial building. The owner, your client, asks you to shrink the footing sizes below what your calculations show is required, arguing that "the building has been standing fine in the neighbourhood for years" and that the savings matter to his budget. He implies he will find another engineer if you refuse.
Analysis:
- Identify the conflict: the client's financial interest versus the safety of the public who will occupy the building.
- Apply the ethics hierarchy: public safety, health, and welfare is paramount — it outranks loyalty to the client.
- Conclusion: you must refuse. Undersizing footings creates a foreseeable risk of settlement or failure, and no client's budget or threat changes the paramount duty.
- Professional follow-through: explain the engineering basis, document your refusal, and if the owner proceeds with another engineer who will do it, the proper course includes notifying the building authority — you do not assist, and you do not stay silent about a known danger.
Answer: Refuse the request; the paramount duty to public safety overrides client loyalty, and the refusal must be documented.
Worked scenario The seal for hire
Situation: A drafting firm that is not run by a licensed engineer offers you a monthly fee to review and seal their structural drawings. The arrangement is presented as efficient: they do the design, you "just stamp it" after a quick look.
Analysis:
- Identify the issue: sealing documents is only permitted for work performed under the engineer's responsible charge — direct personal control and supervision of the design.
- A quick review of someone else's finished work is not responsible charge. Neither is sealing as a paid formality; "plan stamping" is the textbook violation.
- Additionally, sealing work outside one's competence or licence state compounds the violation.
- Conclusion: decline the arrangement. Sealing these drawings would be a violation of the licensure rules and could cost you your licence.
Answer: Decline — a seal requires responsible charge (direct supervision of the work), and stamping another firm's unsupervised designs is an ethical and legal violation.
Worked scenario The second pay cheque
Situation: You work for a consulting firm designing a pump station for a municipality. A contractor bidding on the project offers you a "consulting retainer" to review their bid strategy. The contractor says it is unrelated to your design work and your firm will never know.
Analysis:
- Identify the issues: (1) accepting compensation from a second party on the same project without disclosure — dual compensation; (2) confidentiality — your design knowledge would give the bidder an unfair advantage; (3) undisclosed loyalty split.
- The rule: do not accept payment from more than one party for the same project unless all parties are fully informed and agree. "Nobody will know" is the opposite of disclosure.
- Conclusion: refuse the retainer, and disclose the approach to your employer. If the arrangement were genuinely appropriate, it would survive being disclosed — the secrecy is itself the tell.
Answer: Refuse the retainer and disclose the approach — dual compensation without full disclosure is a conflict-of-interest violation.
