The tuning of A4 to A=440 constitutes an entire section of the PTG tuning exam. When this is scored, the exam piano's A is measured relative to 440 with no consideration for the accuracy of your pitch source. Your pitch source is expected to be accurate. It is usually recommended that examinees tune their tuning fork (ahead of time) to give themselves the best advantage. However, although there are no "compensation factors" in measuring your A for the pitch section of the exam, there _are_ tolerances. If you miss 440 by up to 1.0 cent your pitch score will still be 100. A three cent error on A4 yields the minimum passing pitch score of 80. Kent Swafford
