To find a right teacher online, what do we need to know in advance?
PTNA Teachers' Introduction Service, launched in 1999 to help piano learners to find teachers, increases the items of information onto the basic data - visual images and testimonies. It enables customers to make survey in detail by seeing "virtual lesson rooms".

Information of registered teachers can be viewed online; location, teaching experiences, lesson fee, teaching method, genre, number of students, etc., only their name left unidentified. Besides, photos of lesson rooms, testimonies from students and their parents, parking information, etc. could be important clues to know teachers from various perspectives.
To maintain the credibility of those testimonies, texts are excerpted from documents (STEP evaluation forms) submitted before.

Over 6,000 teachers are currently registered, and 4,140 requests of intermediation came in 2008, which is 220% increase in the last 5 years.
