As a result of the work of the school system, in Cuba there are now seven symphonies, two classical ballet companies of high international prestige, dozens of ballet and modern dance companies and more than 400 troupes at various levels. An indication of the quality of art education in Cuba is the fact that dozens of Cubans actors and actresses are working abroad under contracts almost permanently. In addition, a Cuban is currently the first dancer of the Royal Ballet Theatre of London and another islander was the principal dancer with the American Ballet Theatre of New York.
