IAAO Technical Standards

 Relationship between IAAO Code of Ethics, USPAP and Technical Standards


The IAAO Executive Board adopted the following statement in September 1995 clarifying the relationships among IAAO's standards, the IAAO Code of Ethics and Standards of Professional Conduct, and the Uniform Standards of Professional Appraisal Practice (USPAP), published by the Appraisal Foundation. 

j0409270.jpg "There are 14 different assessment standards that have been adopted by the IAAO. These range from the Standard on Assessment Appeal to the Standard on Mass Appraisal of Real Property to the Standard on the Valuation of Property Affected by Environmental Contamination.  These assessment standards are advisory in nature and their use, or compliance with them, is purely voluntary, not mandatory.  They are to be used by the reader as a tool for instruction.  They are technical advisory road maps for the IAAO member.  Therefore, they are properly called technical assessment standards."  Note: In 1995 when this statement was drafted, there were only 14 standards.
