SCOPE OF WORK RULE
For each appraisal and appraisal review assignment, an appraiser must:
1. identify the problem to be solved;
2. determine and perform the scope of work necessary to develop credible assignment
3. disclose the scope of work in the report.
An appraiser must properly identify the problem to be solved in order to determine the appropriate scope of
work. The appraiser must be prepared to demonstrate that the scope of work is sufficient to produce credible
Comment: Scope of work includes, but is not limited to:
• the extent to which the property is identified;
• the extent to which tangible property is inspected;
• the type and extent of data researched; and
• the type and extent of analyses applied to arrive at opinions or conclusions.
Appraisers have broad flexibility and significant responsibility in determining the appropriate scope of work
for an appraisal or appraisal review assignment.
Credible assignment results require support by relevant evidence and logic. The credibility of assignment
results is always measured in the context of the intended use.
An appraiser must gather and analyze information about those assignment elements that are necessary to
properly identify the appraisal or appraisal review problem to be solved.
Comment: The assignment elements necessary for problem identification are addressed in the applicable
Standards Rules (i.e., SR 1-2, SR 3-2, SR 5-2, SR 7-2, and SR 9-2). In an appraisal assignment, for example,
identification of the problem to be solved requires the appraiser to identify the following assignment
• client and any other intended users;
• intended use of the appraiser’s opinions and conclusions;
• type and definition of value;
• effective date of the appraiser’s opinions and conclusions;
• subject of the assignment and its relevant characteristics; and
• assignment conditions.
This information provides the appraiser with the basis for determining the type and extent of research
and analyses to include in the development of an appraisal. Similar information is necessary for problem
identification in appraisal review assignments.
Communication with the client is required to establish most of the information necessary for problem
identification. However, the identification of relevant characteristics is a judgment made by the appraiser that
requires competency in that type of assignment.
