Free sample problem

A licensed professional engineer is asked to apply a seal to a structural connection design package prepared by an unlicensed designer employed at a different firm. The engineer did not direct or control the preparation of the design but has since reviewed the calculations and found them technically acceptable. Under the NCEES Model Rules, applying the seal is:

  1. (A)Permissible, because the calculations were reviewed and found acceptable
  2. (B)Permissible, provided the originating designer is credited on the drawings
  3. (C)Permissible, provided the engineer accepts liability for the design in writing
  4. (D)Not permissible, because the work was not performed under responsible charge
Show worked solution

Answer: (D)

The seal certifies work prepared by the licensee or under the licensee's responsible charge, and after-the-fact review establishes no such direct control.

Sealing is a certification that the documents were prepared by the licensee personally or under the licensee's responsible charge, which requires direct control and personal supervision while the work is being performed.

Review conducted after completion supplies no control over the assumptions, load paths, and detailing decisions already made, so the responsible-charge test fails even though the reviewer is competent in the subject matter.

Attribution on the title block and a written assumption of liability are contractual devices that never create the supervisory relationship the seal represents, leaving the package unsealable by this engineer.

Why the other choices appear

  • (A)Substitutes technical review for responsible charge, treating a competence check as equivalent to supervision of the work.
  • (B)Assumes credit to the originating designer cures the defect, but disclosure of authorship does not transfer supervisory control to the sealing licensee.
  • (C)Assumes liability may be purchased by contract, whereas the seal attests to how the work was produced, not to who pays for its failure.

When a safety judgment is overruled

An engineer identifies a credible structural hazard in equipment to be opened to the public. The employer overrules the engineer's documented recommendation to correct it. Under NCEES Model Rules 240.15 A, what is the most appropriate next action?

  1. (A)Accept the employer decision because the employer owns the equipment.
  2. (B)Notify the employer or client and an appropriate authority about the danger.
  3. (C)Remain silent until an accident demonstrates the hazard.
  4. (D)Publish confidential drawings on social media before contacting anyone.
Show worked solution

Answer: (B)

Notify the employer or client and an appropriate authority when public safety is endangered by an overruled professional judgment.

The scenario establishes a credible public hazard and an overruled professional judgment. Section 240.15 A.1 makes public health, safety, and welfare the foremost duty.

Section 240.15 A.3 requires notification to the employer or client and an appropriate authority in this circumstance. Document the engineering facts and follow applicable jurisdiction procedures.

The model rule supplies the exam reasoning. It does not justify indiscriminate release of confidential drawings; actual legal duties depend on the jurisdiction and facts.

NCEES Model Rules, August 2025: 240.15 A.1 and A.3; B.4 confidentiality.

Why the other choices appear

  • (A)Ownership does not remove the public-safety duty.
  • (C)Waiting for harm disregards the known hazard and notification duty.
  • (D)Notification to an appropriate authority is not a general license to expose confidential project material.

A financial interest in a vendor

An engineer is evaluating two vendors for a client. The engineer owns a substantial financial interest in one vendor. Both bids meet the technical specification. Under NCEES Model Rules 240.15 B, what should the engineer do before advising the client?

  1. (A)Disclose the financial interest and its potential influence to the client.
  2. (B)Keep the interest private because both bids satisfy the specification.
  3. (C)Choose the other vendor so disclosure is unnecessary.
  4. (D)Accept an undisclosed commission if the favored vendor offers the lower price.
Show worked solution

Answer: (A)

Disclose the known or potential conflict of interest; satisfying the specification does not eliminate the appearance of influence.

The vendor ownership could influence, or appear to influence, the recommendation. The disclosure duty does not require proof that the engineer has already made a biased decision.

Section 240.15 B.6 calls for disclosure to employers or clients of interests or circumstances that may affect judgment or service quality.

Selecting another vendor alone does not communicate the existing interest. An undisclosed commission also introduces a separate gratuity issue under B.5. The question asks for the required first disclosure, not a blanket permission to proceed with every conflict.

NCEES Model Rules, August 2025: 240.15 B.5–B.6.

Why the other choices appear

  • (B)Technical compliance does not remove a financial conflict.
  • (C)Changing the choice without disclosure conceals the known interest.
  • (D)Price does not justify undisclosed vendor compensation.

Three free question types · two 110-question forms

What FE ethics practice questions test

The current NCEES FE Mechanical specification, effective July 2020, assigns 4–6 of the 110 questions to Ethics and Professional Practice. Its listed scope is codes of ethics, public health and safety, intellectual property, and societal considerations. The free responsible-charge question above tests the first two of those topics; it is not a complete review of the whole range.

Use the current NCEES Model Rules and the FE Reference Handbook available through MyNCEES as the official references. The sample answer applies the rule that a licensee may seal only competent work prepared under the licensee's responsible charge. Actual licensing law is set by the relevant jurisdiction; this page is exam practice.

A three-part check for each answer choice

  1. Name the duty. Identify whether the facts concern public welfare, competence, responsible charge, truthful reporting, confidentiality, or a conflict.
  2. Locate the trigger fact. In the free problem, reviewing finished calculations is not the same as directing and controlling the work while it is prepared.
  3. Reject the substitute. Technical acceptability, attribution, or a private liability agreement does not create responsible charge after the fact.
