What is the name for a hula school whose goals are to preserve the hula as an art form and to teach the proper techniques of hula dancing?

   Hula halau (hula hălau)

Explanation:  It is a school that teaches, among other things, a Hawaiian dance style called hula. In translation hălau literally means "long house" and also the branches from which many leaves grow, that is, apart from dance, art is taught, culture from Hawaii in general, and the meaning is roughly an academy, or simply a school, a group. This kind of school or group is usually run by some kind of teacher, like a grand master or alike, who is responsible for transferring the tradition and even the dance as he has accepted and been taught by his teacher to all students. The curriculum of this school therefore implies not only art, tradition and dance, but also the spiritual aspect and development according to this culture. Grand master also teaches healthy lifestyles, nutrition, hygiene, exercise, etc.
