Best school depends very much on the student.  And most importantly what teacher they get! To get a top technique: Cuba (virtuosity, fearlessness) for boys rather then girls Paris Opera (french technique), girls rather then boys? Zurich I believe Stuttgart I believe Kirov Academy (Washington) - not sure how it is now Vaganova (how is it now under Tsikaridze though?) girls Ellison Ballet NY More artistic maybe Hamburg   in UK (always 'careful') probably ENBS   Very good idea to do
