THE AUDITORS CODE
This code first appeared as a chapter in the book Dianetics: The Original Thesis (later retitled The Dynamics of Life) written by L. Ron Hubbard in 1947 and published in 1951.
Subsequently, many hours of auditing ministered by auditors other than Mr. Hubbard provided him with information he was able to apply to refine the code and thus improve the discipline of auditing.
The Auditors Code was revised in 1954, appearing in Professional Auditors Bulletins 38 and 39.
Over the next four years, several additions were made to the 1954 Code, one of which appeared in the book Dianetics 55! Another was released in Hubbard Communications Office Bulletin of 1 July 1957, ADDITION TO THE AUDITORS CODE, and two more items were added when the Auditors Code of 1958 was published.
