A Registered Piano Technician (RPT) has passed a series of rigorous examinations on
the maintenance, repair and tuning of pianos. Only RPTs are authorized by the Piano
Technicians Guild, (PTG), to display the logo containing the words “Registered Piano Technician.”
An Associate in the PTG is a member who has not yet passed the RPT examinations. 
Associates may be studying piano technology and working toward RPT status, or
may be piano retailers, re-builders, refinishers or other specialists in the piano business.
