About Us
Who we are
Founded in 1979, the International Society of Appraisers, or ISA, is the leading professional personal property appraisal association, representing the most highly trained and rigorously tested independent appraisers in the United States and Canada.
ISA is a not-for-profit, member-driven association, formed to support member needs and enhance public trust by producing qualified and ethical appraisers who are recognized authorities in personal property appraising.
In the years since its founding, the Society has grown to be the undisputed personal property association of choice. ISA's Core Course in Appraisal Studies is widely regarded as the most comprehensive in the industry, distinguishing ISA as the leader in methodology, theory, principles, practices, and ethics. We also offer extensive professional development in specific areas of product knowledge and connoisseurship, both through coursework and continuing education offerings at our annual conference.
