What is the highest mark in a piano exam?

The highest mark in most piano exams is usually denoted as a "Distinction" or its equivalent. The exact criteria for achieving a distinction may vary depending on the specific examination board or institution, but it generally indicates an exceptional level of performance and musicianship beyond the requirements for a pass or merit grade. To obtain a distinction, candidates are expected to demonstrate advanced technical proficiency, musical interpretation, and a comprehensive understanding of the pieces they are required to perform.
