Yes. The application process is completely open to those aged 18 and above. There is no upper age restriction for applying to the NOS. However, applicants are reminded that the Young Artists' Programme is very intensive and is intended to benefit extremely gifted singers and répétiteurs who are at the beginning of their professional operatic careers. Although it is not a formal requirement, applicants are expected to have a great deal of performance experience and to have been training, in some form, for a number of years.
