Advanced Personal Property Appraisal Course (APPA)

The APPA is an advanced home-study program in personal property appraising. The three-part complete program offers a new level of professional training for personal property appraisers.

The Advanced Personal Property Appraisal program is especially appropriate for those who currently practice or who are interested in practicing personal property appraising. While the program is applicable to jewelry appraisal, it teaches all aspects of personal property appraising. APPA I includes topics on ethics, values, authentication and confidentiality; APPA II includes report writing, insurance, warranties, bailment, contracts and disputes; and APPA III chapters address estate settlements, trusts, tax liability, criminal and civil litigations, sales and barter, and divorce, resolving any doubt about how to render an appropriate appraisal in the context of its assigned use and controlling law. The home study student submits lessons to AGS for grading via U.S. Mail or fax.Upon successful completion of all three parts and the proctored final exam, an Advanced Personal Property Appraisal Certificate will be sent from the Jewelers Education Foundation of the AGS.

The APPA course was developed by AGS Appraisals Chair, Cos Altobelli, and researched and written by William Hoefer with support from specialists on the AGS Appraisals Committee. While the American Gem Society underwrote it, the program is available to all appraisers and is intended to increase professionalism among the broad appraisal community.

The APPA course is an online PDF and cost $795.
