International Society of Appraisers

The International Society of Appraisers (ISA), founded in 1979, is the largest of the professional personal property appraisal associations representing the most highly trained and rigorously tested independent appraisers in the United States and Canada. 


The ISA is a not-for-profit, member-driven association, formed to support and enhance public trust by producing qualified and ethical appraisers who are recognized authorities in personal property appraising.


An ISA education is widely regarded as the most comprehensive in the industry distinguishing the International Society of Appraisers as the leader in methodology, theory, principles, practices, and ethics with extensive professional development in specific areas of product knowledge and connoisseurship.

What is USPAP?

The Uniform Standards of Professional Appraisal Practice (USPAP) was adopted by Congress in 1989. USPAP is the recognized ethical and performance standard for the appraisal profession in the United States as well as countries worldwide.  USPAP is updated every two years and all ISA affiliated appraisers must pass requalification to remain in good standing.


Valuations for tax purposes are strongly advised by the U.S. IRS to meet USPAP standards. ISA trained appraisers are required to be fully trained in USPAP and compliant.
