GPPA is different from NAA’s other designations in two ways: It’s longer (five days), and it’s not about auctions. GPPA is designed to give auctioneers both more skill and acumen in appraising personal property and also another potential revenue stream as a professional appraiser. Attendees learn to appraise all types of personal property, from art to antiques, heavy equipment to general household goods, vehicles to collectibles. The class focuses on process rather than asset class: attendees complete a minimum of three appraisals in class. GPPA teaches attendees to appraise according to USPAP (Uniform Standards of Professional Appraisal Practice), which is a two-day class also offered by NAA.
