These professional status categories are awarded to individuals, not to corporations or other business organizations. Only Senior Appraisers may use the designation “ISTAT” after their names. An Appraiser Fellow may use the designation “FISTAT.” The category of “Candidate” is established to formalize the status of applicants wishing to join the program.
“Appraiser” status requires a minimum of five years employed full time in aviation-related business, of which no less than two years shall have been spent in accomplishing aircraft appraisals.
Ethical practices and conduct required of the appraisers accredited by the Society are clearly defined in the ISTAT publication, Principles of Appraisal Practice and Code of Ethics.
