Similar to medicine, law and religious ordination, engineering is considered a "profession" rather than an "occupation" because of the characteristics shared with other learned professions: special knowledge, special privileges, and special responsibilities. Because of their importance to society, professions require a large knowledge base gained from extensive training and apprenticeship.

Professions control the training and evaluation processes that admit new practitioners to their fields. They have autonomy in the workplace; they are expected to utilize their independent judgment in carrying out their professional responsibilities. Perhaps most importantly, professions are regulated by rigorous ethical standards. (Harris, Pritchard & Rabins; Engineering Ethics, Wadsworth Publishing,1995.)

In order to serve society effectively, engineers must maintain a high level of technical competence. However, a high level of technical expertise without adherence to ethical guidelines is as much a threat to public welfare as is professional incompetence. The ethical principles governing engineering professions are embodied in codes of ethics. Such codes have been adopted by state boards of registration, professional engineering societies, and private industries.

Just as individual states base their constitutions on the U.S. Constitution, state engineering boards base their ethical codes on a set of Model Rules written by the National Society of Professional Engineers (NSPE). In some cases, state boards wholly adopt the Model Rules, while in others, changes must be made to align the rules with existing state laws and court decisions.

The American Society of Legal Engineers based their model rules on the NPSE Model Rules, and will modify their rules as needed to advance the profession of Legal Engineering. As the profession gains acceptance, state boards of professional oversight are encouraged to adopt rules based on the ASLE model rules.

No code can give immediate and mechanical answers to all ethical and professional problems that an engineer may face. Creative problem solving is often called for in ethics, just as it is in other areas of engineering.

The American Society of Legal Engineers Model Code of Ethics


Engineering is an important and learned profession. As members of this profession, engineers are expected to exhibit the highest standards of honesty and integrity. Engineering has a direct and vital impact on the quality of life for all people. Accordingly, the services provided by engineers require honesty, impartiality, fairness, and equity, and must be dedicated to the protection of the public health, safety, and welfare. Engineers must perform under a standard of professional behavior that requires adherence to the highest principles of ethical conduct.

1) Fundamental Canons

Engineers, in the fulfillment of their professional duties, shall:

a. Hold paramount the safety, health, and welfare of the public.

b. Perform services only in areas of their competence.

c. Issue public statements only in an objective and truthful manner.

d. Act for each employer or client as faithful agents or trustees.

e. Avoid deceptive acts.

f. Conduct themselves honorably, responsibly, ethically, and lawfully so as to enhance the honor, reputation, and usefulness of the profession.

2) Diversity and Inclusion

a. Engineers recognize the value of diverse teams and the varied perspectives they bring.

b. To enable engineers to be fully engaged in their work, they must feel included and valued. Engineers should strive to build and nurture a culture where inclusiveness is a reflex, not an initiative. A deep sense of pride, passion and belonging transcends any role, language or country and is unified in engineer's shared commitment to excellence, innovation and social responsibility.

c. Engineers know through experience that different ideas, perspectives and backgrounds create a stronger and more creative work environment that delivers better results.

d. To support an inclusive environment where engineers and their co-workers feel empowered to share their experiences and ideas, the ASLE encourages the creation of a variety of engineer resource groups, including groups for Women, Veterans, LGTBQ (Pride & Allies), African and Minority Ancestry, Developing Professionals and more.

3) Public Interest

a. If an engineer’s judgment is overruled under circumstances that endanger life or property, they shall notify their employer or client and such other authority as may be appropriate.

b. Engineers shall not complete, sign, seal, push or post plans, specifications or software that are not in conformity with applicable engineering standards. If the client or employer insists on such unprofessional conduct, they shall notify the proper authorities and withdraw from further service on the project.

c. Engineers are encouraged to extend public knowledge and appreciation of engineering and its achievements.

d. Engineers are encouraged to participate in civic affairs; career guidance for youths; and work for the advancement of the safety, health, and well-being of their community.

e. Engineers are encouraged to adhere to the principles of sustainable operations to protect the environment for future generations.

d. Engineers shall not promote their own interest at the expense of the dignity and integrity of the profession.

e. Engineers shall accept personal responsibility for their professional activities, provided, however, that engineers may seek indemnification for services arising out of their practice for other than gross negligence, where the engineer's interests cannot otherwise be protected.

a. Engineers shall act for each employer or client as faithful agents.

b. Engineers shall disclose all known or potential conflicts of interest that could influence or appear to influence their judgment or the quality of their services.
