What Is USPAP? A Guide to Art Appraisal Standards
Most collectors think about an art appraisal only when someone asks for one: an insurer scheduling a new acquisition, an attorney settling an estate, or a donor preparing a charitable contribution. By then, the question is not only what a work is worth, but whether the appraiser's opinion of value is credible, well-supported, and appropriate for its intended use.
What Is USPAP?
USPAP stands for the Uniform Standards of Professional Appraisal Practice. USPAP sets standards for ethical and competent appraisal practice across disciplines, including personal property appraisal, in the United States. It is written and updated by the Appraisal Standards Board of The Appraisal Foundation, a congressionally authorized organization that develops appraisal standards and qualifications.
An appraisal is an opinion of value. The appraiser develops that opinion based on the purpose of the assignment, the applicable definition of value, the characteristics of the property, relevant market evidence, and the appraiser's analysis. The opinion applies as of a specific effective date and is developed for a specific intended use.
Why Does USPAP Matter for Art Appraisals?
Fine art falls within the personal property appraisal discipline. Unlike real estate appraisal, personal property appraisers are not subject to a nationwide state licensing system. Instead, appraisers demonstrate their qualifications through professional credentials, education, experience, and adherence to appraisal standards. USPAP provides a recognized framework for ethical and competent appraisal practice across disciplines.
Personal property appraisers typically demonstrate their knowledge of USPAP by completing the 15-Hour National USPAP Course and exam, then staying current through the 7-Hour USPAP Update Course every two years. Individual credentialing organizations may impose additional education and experience requirements.
What Does USPAP Require of an Appraiser?
USPAP is detailed, but its core principles are straightforward.
Impartiality: An appraiser must act independently and without bias. Under the USPAP Ethics Rule, compensation cannot be contingent on reporting a predetermined value, reaching a specific result or direction in value, or the outcome of the assignment. A fee that depends on the appraised value would give the appraiser a financial incentive to reach a particular conclusion. This is why a reputable appraiser will not charge a percentage of what your art is worth.
Confidentiality: USPAP requires appraisers to protect confidential information obtained during an assignment. An appraiser may not disclose confidential information or assignment results to anyone other than the client, people the client authorizes, state appraiser regulatory agencies, third parties as permitted by due process of law, or a duly authorized professional peer review committee.
Competency: An appraiser must have the knowledge and experience necessary for the assignment. If they lack competency for a particular assignment, they must disclose that fact, take appropriate steps to gain competency, and disclose the steps taken. This may include consulting a qualified specialist.
Scope of work: An appraiser identifies the problem to be solved, the intended use and users of the appraisal, the definition of value, the effective date, the property being appraised, and the research and inspection necessary to produce credible assignment results.
A clear and credible report: The appraisal report should communicate the relevant characteristics of the property, the analysis performed, and the basis for the value conclusion so that the intended users can understand how the appraiser reached the result.
Prior services and other disclosures: USPAP requires disclosure of prior services involving the subject property and of other circumstances that could affect an appraiser's objectivity or create a conflict of interest.
Record keeping: Under the USPAP Record Keeping Rule, an appraiser must retain the workfile for at least five years after preparation or at least two years after final disposition of any judicial proceeding in which the appraiser provided testimony related to the assignment, whichever period expires last.
What USPAP Does Not Do
USPAP does not set the value of a work of art or guarantee a particular opinion of value. Instead, it establishes standards for how an appraisal assignment should be developed and communicated.
The opinion of value depends on the purpose of the appraisal, the definition of value being used, the characteristics and condition of the property, relevant market evidence, and the appraiser's analysis. In other words, USPAP provides the framework for a credible appraisal. It does not provide a formula for determining what a work of art is worth.
When Is a USPAP-Compliant Art Appraisal Important?
An appraisal is only as useful as the confidence others place in it. Insurers rely on a well-supported opinion of value when scheduling a work on a policy or evaluating a claim. Attorneys, fiduciaries, and courts need an appraisal that can withstand scrutiny in an estate settlement, equitable distribution, or other legal proceeding.
Charitable contributions are another important example. The IRS has specific requirements for qualified appraisals and qualified appraisers, including that the appraisal be prepared in accordance with the substance and principles of USPAP. Generally, if the claimed deduction for an item or group of similar items of donated property exceeds $5,000, the donor must obtain a qualified appraisal. Additional reporting and documentation requirements may apply depending on the amount claimed and the type of property.
Because tax requirements can change and may depend on the circumstances of a particular contribution, donors should consult their tax adviser about the requirements that apply to their situation.
For collectors, a well-supported appraisal also provides a lasting record of what you own, an opinion of value, and the basis for that conclusion.
Questions to Ask Before Hiring an Art Appraiser
A brief conversation before you engage an appraiser can tell you a great deal. We suggest asking:
Is your appraisal being performed in accordance with USPAP, and is your USPAP education current?
How is your fee calculated?
Which definition of value will you use, and why is it appropriate for my purpose?
Have you or your firm previously provided services involving this work?
Will you inspect the work in person, or will you work from photographs and documents?

The Bottom Line
USPAP provides a common professional framework for producing credible, well-supported appraisals. But the standard is only one part of evaluating an appraiser. When selecting a fine art appraiser, consider the appraiser's education, experience, professional credentials, subject-matter expertise, independence, and understanding of how the report will be used.
