Professional Conduct
The NCEES Model Rules (pp. 4-5) define three tiers of obligations: to the public, to employers and clients, and to other licensees. Public safety is always the paramount duty — it overrides client wishes, budget pressures, and employer directives. The FE tests this with scenario questions where you must identify the correct course of action when obligations conflict.
Licensure & Law
The Model Law (pp. 6-10) defines who can call themselves a Professional Engineer, what constitutes the practice of engineering, the FE-to-PE licensure path, and what gets your license revoked. On the FE, expect questions about education and experience requirements, what an Engineer Intern can and cannot do, and which actions constitute grounds for disciplinary action.
Contracts & Liability
Engineering services are delivered under contracts, and engineers carry legal responsibility for their work. You should know what makes a contract enforceable (offer, acceptance, consideration), how contract types and project delivery methods allocate cost risk, and how professional liability turns on the standard of care and the four elements of negligence. The FE tests these as scenario questions on contracts, delivery methods, and liability.
Broader Responsibilities
Beyond the code of conduct, engineers must understand intellectual property protections (patents, trademarks, copyrights, trade secrets) and sustainability principles (life-cycle analysis, environmental stewardship). The handbook covers these on pp. 12-13. Expect 1-2 questions asking which IP protection applies to a given scenario or which practice qualifies as sustainable design.
