Royal Ballet has six ranks of dancers: Artist: the lowest rank in the company. Together with the First Artists, dancers at this level form the Corps de ballet. Ballet school graduates entering the company usually do so at this level. First Artist: Dancers at this level have the opportunity to perform some of the Corps de Ballet's more featured rôles, such as the Dance of the Cygnets in Swan Lake. First Artists will occasionally be cast in minor Soloist rôles if they are being considered for promotion. Soloist: a rank normally occupied by 15–20 dancers in the company, who perform most of the solo and minor rôles, such as Mercutio in Romeo and Juliet or one of the Fairies in The Sleeping Beauty. First soloist: the rank at which dancers are being considered for promotion to Principal. A dancer at this rank will dance a varied repertoire of the most featured soloist rôles, whilst understudying principals and so performing leading rôles when a Principal dancer is injured or unavailable. Principal character artist: the rank given to members of the company who perform important character rôles in a ballet. These rôles are normally very theatrical and often include character dance and ballet mime. Examples include Carabosse in The Sleeping Beauty or Drosselmeyer in The Nutcracker. Most Principal Character Artists in the Royal Ballet are older, long-serving members of the company who are no longer able to dance the more physically challenging roles. Principal: the highest rank in the Royal Ballet. Dancers at this level are the leading dancers in the company, and generally perform the most demanding and prominent rôles in a ballet. Many of the world's most celebrated dancers have been principals with the company. The Royal Ballet also has the special ranks of "guest artist" and "principal guest artist". The title of guest artist is given to a visiting dancer who has been cast in a role for a specific ballet or limited season. The title of principal guest artist is sometimes given to guest artists who perform with the company on a longer-term basis. The company The Royal Ballet employs approximately 100 dancers and a complete list as of 2013 is shown below. The company also has an Executive, Artistic and Music staff, including the following: Director – Kevin O'Hare, a graduate of the Royal Ballet School and former dancer with The Royal Ballet and Birmingham Royal Ballet
