Real estate is one of the basic sources of wealth in the global economy. Therefore, those who own, manage, sell, purchase, invest in, or lend money on the security of real estate must have ready access to the services of individuals who provide unbiased opinions of value, as well as sound information, analyses, and advice on a wide range of issues related to property economics. For these reasons, the services of valuers are vital to the well-being of our society and the global economy, and foster economic growth, stability, and public confidence.

Because of this vital role and a commitment to professionalism, the Appraisal Institute has adopted a Code of Professional Ethics and Standards of Professional Practice to establish requirements for ethical and competent practice. These requirements also serve to promote and maintain a high level of public trust and confidence in Appraisal Institute Members, Candidates, practicing Affiliates, and Affiliates.

In addition, the Appraisal Institute has developed a sophisticated peer review system through which it enforces its Code of Professional Ethics and Standards of Professional Practice. Violations of the Code of Ethics or Standards can result in remedial or disciplinary actions.
