The ancient Jedi scholar Karena
coined the term praxeum to describe a Jedi academy as a place for the
"distillation of learning combined with action." In the days of the Galactic Republic, well-known praxeums included those on Teya IV, Arkania, Ossus and Dantooine.
The only Jedi Praxeum during the time of the New Republic was founded by Luke Skywalker on Yavin 4 in 11 ABY to train new Jedi.
