I heard from my friends that they make the students practice 8 hours a day... (No wonder why Rachmaninoff skipped his classes...) But I don't know if this is true. The Russian and German schools are known as "pianist factories", with exaustive practice and traditional teaching and practicing methods... But we have pretty good results from it: Rachmaninoff, Glinka, Valentina Igoshina, many others...
Especially during Rachmaninoff's time, I believe that they used physical violence as part of their teaching...

. I know that in Brazil in the early 1900's they did! They would hit your hands with a stick if you missed any notes...
Well, limiting students only to practice seems like a fair method, except if the student has enough talent that he needs freedom to practice what he wishes...
Well, as Rachmaninoff said: Only the art that is free has true meaning...
I wish I could go in one of those conservatoires...
