Final answer:
The preamble of the National Association of Realtors (NAR) Code of Ethics states that the interests of the nation and its citizens require the 'highest standards of professionalism' from REALTORS. Ethics codes like NAR's ensure that professionals conduct their business with skill and integrity. Similar ethical standards are echoed in professional organizations across various fields.
Step-by-step explanation:
According to the preamble of the National Association of Realtors (NAR)'s Code of Ethics, "REALTORS should recognize that the interests of the nation and its citizens require the highest standards of professionalism." This emphasis on professionalism means that REALTORS are expected to conduct their business activities with a high level of skill, integrity, and adherence to ethical standards. Professional organizations, like NAR, put forward such codes of ethics to ensure that their members act in ways that honor the trust placed in them by the public and uphold the dignity of their profession. Similar to the code provided by the Institute of Electrical and Electronics Engineers (IEEE), which expects software engineers to commit to ethical obligations, including safety and privacy concerns, the NAR's Code of Ethics upholds the duty of real estate professionals to serve their clients and the public conscientiously and competently.
