The APPA course stared in 1998 and was offered through The Jewelers Education Foundation of the American Gem Society (AGS) as developed by Cos Altobelli, ECGA AGS. The author of the course was William D. Hoefer, Jr. GG (GIA), FGA.
Cos, in his latest book, The Practical Guide to Jewelry Appraising published in 2022, stated: "It is the most through, far-reaching formal appraisal course offered in the world today and is available in a home-study format." In explaining the difference between the AGS' CGA program and the APPA course, he detailed: "The CGA and APPA programs are not at all in conflict with one another. The CGA program is a basic appraisal course, the APPA is a formal, more complete approach to appraising. There are some minor overlapping, however, the two programs truly compliment one another."2
