About ISA


 Background and Mission Statement

The International Society of Appraisers (ISA) was established in 1979 as a for-profit corporation focused on the education and professionalism of personal property appraisers.  It became a not-for-profit corporation in 1994; and remains committed to the same goals. ISA has been a leader in rationalizing practices, theory, methodology and report writing standards directed to the appraisal of personal property. Our members include many of the country’s most respected personal property appraisers, consultants, estate liquidators, auctioneers, gallery owners and dealers.

ISA offers a comprehensive professional development program designed to build and enhance performance in the area of personal property appraisal practice as well as specialty studies.  Our four main divisions are comprised of:  1) antiques and residential contents; 2) fine art; 3) gemstones and jewelry; and 4) machinery and equipment. ISA’s professional development and credentialing programs, along with its strong code of ethics and professional conduct, serve as the foundation of the organizational mission—to advance the professionalism and effectiveness of personal property appraisers.


The ISA Commitment

The ISA philosophy embraces the protection of the public’s right to expect appraisals that reflect the utmost in accuracy, competency and integrity.
